About this Guide
This guide provides instructions on how to install your Cisco Catalyst Series 9105AXW and 9105AXWT access points and provides links to resources that can help you configure it. This guide also provides mounting instructions and troubleshooting information.
Note that the C9105AXW and C9105AXWT access points are referred to as the access point or the AP in this document.
About the Cisco Catalyst Series 9105AXW and 9105AXWT Wireless Access Points
The Cisco Catalyst 9105AXW and 9105AXWT series wireless access points are advanced dual-band, dual-concurrent, enterprise 802.11ax (Wi-Fi 6) APs with integrated antennas. These wall-mounted APs support 2x2:2 SS MU-MIMO applications and are designed to use both 2.4 GHz and the 5 GHz bands. The APs support full interoperability with leading 802.11ax and 802.11ac clients, along with a mixed deployment with other APs and controllers.
A full listing of the AP's features and specifications are provided in the Cisco Catalyst 9105AXW and 9105AXWT Series Access Point Data Sheet, at the following URL:
https://www.cisco.com/c/en/us/products/collateral/wireless/catalyst-9100ax-access-points/datasheet-c78-744062.htmlThe access point remains the same for both the models, the difference is in the mounting of the AP.
The Cisco Catalyst 9105AXW AP uses the wall mountable bracket (AIR-AP-BRACKET-W4) that allows the AP to be installed vertically on a wall. This model is suited for hospitality, residence halls, or other multi-dwelling units.
Note Installing the AIR-AP-BRACKET-W4 does not require redrilling as it shares the same mounting holes as the AIR-AP-BRACKET-W3.
The Cisco Catalyst 9105AXWT AP uses the cradle allowing the AP to be placed horizontally on a desk. This AP establishes a highly secured enterprise wireless and wired connection to the home, micro-branch, or other types of remote sites. This access point extends the corporate network to teleworkers, mobile workers, or micro-sites, providing experience consistent with that at the corporate office.
Cisco Catalyst Series 9105AXW and 9105AXWT Wireless Access Point Features
The C9105AXW and C9105AXWT wireless APs are wireless controller-based products and support the following features:
n Two dual-band internal antennas and one single-band internal IoT–BLE antenna in both the C9105AXW and C9105AXWT-x AP models
Note The ‘x’ in the model numbers represents the regulatory domain. For information on supported regulatory domains, see the AP Model Numbers and Regulatory Domains.
n Integrated antennas that are directional in azimuth, for both 2.4 GHz (peak gain 3dBi) and 5 GHz (peak gain 5dBi) bands.
n The following hardware external interfaces:
— 1x100/1000/2500 Multigigabit Ethernet (RJ-45)
— 3x10/100/1000 BASE-T Ethernet (RJ-45)
— RS-232 console interface through RJ-45
Note The AP may face issues while booting if you use an unterminated console cable (not plugged into any device or terminal) or a console cable that is more than one meter in length.
— Passive pass-through port (RJ-45)
— Mode button (enables partial or full system configuration recovery)
n One multi-color LED Status indicator. see the Checking the Access Point LEDs for information on the colors of the LED status indicator.
n Simultaneous 2x2 Multiple-Input Multiple-Output (MIMO) with 2 spatial streams for both 2.4 GHz and 5 GHz bands.
n Multiuser (MU) MIMO technology with 2 spatial streams for downlink.
n MIMO equalization capabilities, which optimize uplink performance and reliability by reducing the impact of signal fade.
n Orthogonal Frequency Division Multiple Access (OFDMA)-based scheduling for both uplink and downlink.
n Spatial Reuse (also known as Basic Service Set (BSS) coloring) which allows APs and their clients to differentiate between BSSs, thus permitting more simultaneous transmissions.
n New power savings mode called Target Wake Time (TWT) which allows the client to stay asleep and wake up only at pre-scheduled (target) times to exchange data with the AP. This provides significant energy savings for battery-operated devices.
n Cisco Catalyst Center support enables Cisco Spaces, Apple FastLane and Cisco Identity Services Engine.
n Cross-AP Noise Reduction, a Cisco innovation that enables APs to intelligently collaborate in real time about RF conditions so that users connect with optimized signal quality and performance.
n Optimized AP Roaming for ensuring that client devices associate with the AP in their coverage range that offers the fastest data rate available.
n Cisco CleanAir delivers proactive, high-speed spectrum intelligence across 20-, 40-, and 80-MHz-wide channels to combat performance problems arising from wireless interference.
This AP supports both lightweight deployments (using Cisco Wireless Controllers) and Cisco Embedded Wireless Controller deployments. The AP can operate in the following modes:
n Local: This is the default mode for the Cisco AP. In this mode, the AP serves clients.
In local mode, the AP creates two CAPWAP tunnels to the Cisco WLC, one for management and the other for data traffic. This is known as central switching because the data traffic is switched (bridged) from the AP to the controller where it is then routed.n FlexConnect: In FlexConnect mode (previously known as HREAP), the data traffic is switched locally and is not sent to the controller. In this mode, the Cisco AP behaves like an autonomous AP, but is managed by the Cisco WLC. Here, the AP continues to function even if connection to the controller is lost.
n Monitor: In the monitor mode, specified Cisco APs can exclude themselves from handling data traffic between clients and the infrastructure. These APs act as dedicated sensors for location based services (LBS), rogue AP detection, and intrusion detection (IDS).
When APs are in monitor mode, they actively monitor the airwaves and typically do not serve clients.n Sniffer: In the wireless sniffer mode, the AP starts sniffing the air on a given channel. It captures and forwards all the packets from the clients on that channel to a remote machine that runs Airopeek or Wireshark (packet analyzers for IEEE 802.11 wireless LANs). This includes information on the time stamp, signal strength, packet size, etc.
Note In the sniffer mode, the server to which the data is sent should be on the same VLAN as the wireless controller management VLAN otherwise an error will be displayed.
AP Model Numbers and Regulatory Domains
You need to verify whether the AP model you have is approved for use in your country. The x in the model number is a placeholder for the regulatory domain. To verify approval and to identify the regulatory domain that corresponds to a particular country, visit http://www.cisco.com/go/aironet/compliance . Not all regulatory domains have been approved. As and when they are approved, this compliance list will be updated.

Preparing the AP for Installation
Before you mount and deploy your access point, we recommend that you perform a site survey (or use the site planning tool) to determine the best location to install your access point.
You should have the following information about your wireless network available:
n Access point mounting options: below a suspended ceiling, on a flat horizontal surface, or on a desk top.
Note You can mount the access point above a suspended ceiling but you must purchase additional mounting hardware: See Mounting the Access Point for additional information.
n Access point power options: 802.3at (PoE+) (Cisco Power Injector AIR-PWRINJ6=), 802.3af (Cisco Power Injector AIR-PWRINJ5=), Cisco Universal PoE (Cisco UPOE), or hub (usually located in a wiring closet).
n Operating temperature: 32°—122°F (0°—50°C)
Note When installing the AP in an environment where the ambient temperature is in the range of 104°—122°F (>40°—50°C), the access point configuration will change from 8x8 to 4x4 on the 5 GHz radios and the uplink Ethernet will downgrade to 1GbE. However, the USB port will remain enabled.
Cisco recommends that you make a site map showing access point locations so that you can record the device MAC addresses from each location and return them to the person who is planning or managing your wireless network.
Installation Overview
Installing the access point involves these operations:
Performing a Pre-Installation Configuration
Note Performing a pre-installation configuration is an optional procedure. However, performing this procedure ensures that your access point installation and initial operation go as expected.
If your network controller is properly configured, you can install your access point in its final location and connect it to the network from there. See the Deploying the Access Point on the Wireless Network for details.
The pre-installation configuration setup is illustrated in Pre-Installation Configuration Setup .
Pre-Installation Configuration Setup
For pre-installation configuration, perform the following steps:
- Make sure that access points have Layer 3 connectivity to the Cisco Wireless Controller Management and AP-Manager Interface.
- Configure the switch to which your access point is to attach. See the Cisco Wireless Controller Configuration Guide for the release you are using, for additional information.
- Set the Cisco Wireless Controller as the primary so that new access points always join with it.
- Make sure DHCP is enabled on the network. The access point must receive its IP address through DHCP.
Note An 802.11ax Cisco AP will be assigned an IP address from the DHCP server only if a default router (gateway) is configured on the DHCP server (enabling the AP to receive its gateway IP address) and the gateway ARP is resolved.
- CAPWAP UDP ports must not be blocked in the network.
- The access point must be able to find the IP address of the controller. This can be accomplished using DHCP, DNS, or IP subnet broadcast. This guide describes the DHCP method to convey the controller IP address. For other methods, refer to the product documentation. See also the Configuring DHCP Option 43 for more information.
Note The access point requires a gigabit Ethernet (GbE) link to prevent the Ethernet port from becoming a bottleneck for traffic because wireless traffic speeds exceed transmit speeds of a 10/100 Ethernet port.
- Apply power to the access point. See Powering the Access Point.
- As the access point attempts to connect to the controller, the status LED alternates between red and green. This can take up to 5 minutes.
Note If the access point remains in this mode for more than five minutes, it indicates that the access point is unable to find the primary Cisco Wireless Controller. Check the connection between the access point and the Cisco Wireless Controller and be sure that they are on the same subnet.
- If the access point shuts down, check the power source.
- After the access point finds the Cisco Wireless Controller, it attempts to download the new operating system code if the access point code version differs from the Cisco Wireless Controller code version. While this is happening, the Status LED blinks blue.
- If the operating system download is successful, the access point reboots.
- Configure the access point if required. Use the controller CLI, controller GUI, or Cisco Prime Infrastructure to customize the access-point-specific 802.11ax network settings.
- If the pre-installation configuration is successful, the Status LED is green indicating normal operation. Disconnect the access point and mount it at the location at which you intend to deploy it on the wireless network.
- If your AP does not indicate normal operation, turn it off and repeat the pre-installation configuration.
Mounting the Access Point
Cisco Catalyst 9105AXW series access points can be mounted directly on a wall or on an electrical or network box, to numerous global wall junction standards.
When mounting the AP in areas where there is a possibility of the AP being knocked off the mounting bracket, use the lock hasp on the back of the AP to lock it to the bracket.
Mounting the AP directly on a Wall
To mount the AP on a wall, follow these steps:
If you are unable to connect a PoE cable to the port on the back of the AP, then:
- On the back of the AP, use an RJ45 jumper cable to connect the PoE port to the Pass-Through port. This jumper cable is available as part of the spacer kit (C9105AXW-KIT=).
- Connect the PoE supply cable to the Pass-Through port on the base of the AP.
This connection sends power internally from the Pass-Through port on the base, to the Pass-Through port on the back, and then though the jumper cable into the PoE port on the back.
Mounting the AP on an Electrical Junction Box
To mount the AP on an electrical junction box, follow these steps:
If you are unable to connect a PoE cable to the port on the back of the AP, then:
- On the back of the AP, use an RJ45 jumper cable to connect the PoE port to the Pass-Through port. This jumper cable is available as part of the spacer kit (C9105AXW-KIT=).
- Connect the PoE supply cable to the Pass-Through port on the base of the AP.
This connection sends power internally from the Pass-Through port on the base, to the Pass-Through port on the back, and then though the jumper cable into the PoE port on the back.

The spacer kit helps mount the AP on a wall. Use this kit when there are space constraints to mount the AP. The spacer kit (C9105AXW-KIT=) is optional and needs to be added along with the AP order or purchased separately.
To mount the AP on a wall using a spacer box, follow these steps:
- Fasten the wall-mount bracket (AIR-AP-BRACKET-W4) to the spacer box, using two M3X8mm tapping screws. Ensure that the side having the Mount Arrows Up label is facing outwards, and the bracket is oriented vertically as indicated by the arrows.
- Connect the power and network cables to the AP.
If you are unable to connect a PoE cable to the port on the back of the AP, then:
- On the back of the AP, use an RJ45 jumper cable to connect the PoE port to the Pass-Through port. This jumper cable is available as part of the spacer kit (C9105AXW-KIT).
- Connect the PoE supply cable to the Pass-Through port on the base of the AP.
This connection sends power internally from the Pass-Through port on the base, to the Pass-Through port on the back, and then though the jumper cable into the PoE port on the back.
Note The punch-out holes on the spacer box can be used for routing cables. However, an RJ45 connector will not fit through these holes. If this is required, you must first route a cable through the hole and then crimp an RJ45 connector on to the cable.
Mounting the AP on an Electrical Junction Box using the Spacer
The spacer kit helps mount the AP on an electrical junction box. This spacer avoids exposing Ethernet cable to the elements. The the pass-through Ethernet port is used to connect the Ethernet cable to the AP.

To mount the AP on an electrical junction box using a spacer box, follow these steps:
- Fasten the wall-mount bracket and spacer box assembly to the electrical junction box, using two #6-32X1.62 inch machine screws. Ensure that the side having the Mount Arrows Up label is facing outwards, and the box is oriented vertically as indicated by the arrows.
- Connect the power and network cables to the AP.
If you are unable to connect a PoE cable to the port on the back of the AP, then:
- On the back of the AP, use an RJ45 jumper cable to connect the PoE port to the Pass-Through port. This jumper cable is available as part of the spacer kit C9105AXW-KIT.
- Connect the PoE supply cable to the Pass-Through port on the base of the AP.
This connection sends power internally from the Pass-Through port on the base, to the Pass-Through port on the back, and then though the jumper cable into the PoE port on the back.
Note The punch-out holes on the spacer box can be used for routing cables. However, an RJ45 connector will not fit through these holes. If this is required, you must first route a cable through the hole and then crimp an RJ45 connector on to the cable.
Mounting the Kit C9105AXWT_COVER= to the AP
Mounting the C9105AXWT_COVER to the AP
The cover—C9105AXWT_COVER for the Cisco Catalyst 9105AXWT allows you to place the AP horizontally on the desk. This kit contains the back cover with rubber feet, RJ-45 jumper cable, and mylar cover for the screw slot at the top of the AP.
To mount the Kit C9105AXWT_COVER= to the AP, follow these steps:
- On the back of the AP, use an RJ45 jumper cable to connect the PoE port to the Pass-Through port. This jumper cable is available as part of the teleworker kit (C9105AXWT_COVER=). Bend the cable as shown in Powering the Access Point.
- Connect the PoE supply cable to the pass-through port on the base of the AP.
This connection sends power internally from the Pass-Through port on the base, to the Pass-Through port on the back, and then though the jumper cable into the PoE port on the back.
Powering the Access Point
The AP can be powered only through Power-over-Ethernet (PoE) using the following:
n 802.3at (PoE+): Any 802.3at (30.0 W) compliant switch port or Cisco Power Injector AIR-PWRINJ6=
n 802.3af: Any 802.3af (15.4 W) compliant switch port or Cisco Power Injector AIR-PWRINJ5=
Note If 802.3af is used, the USB port and LAN PSE1 port will be off.
Configuring and Deploying the Access Point
This section describes how to connect the access point to a controller. Because the configuration process takes place on the controller, see the Cisco Wireless Controller Configuration Guide for additional information.
The Controller Discovery Process
- You cannot edit or query any access point using the controller CLI if the name of the access point contains a space.
- Make sure that the controller is set to the current time. If the controller is set to a time that has already occurred, the access point might not join the controller because its certificate may not be valid for that time.
Access points must be discovered by a controller before they can become an active part of the network. The access point supports these controller discovery processes:
n Locally stored controller IP address discovery—If the access point was previously joined to a controller, the IP addresses of the primary, secondary, and tertiary controllers are stored in the access point non-volatile memory. This process of storing controller IP addresses on an access point for later deployment is called priming the access point. For more information about priming, see the Performing a Pre-Installation Configuration.
n DHCP server discovery—This feature uses DHCP option 43 to provide controller IP addresses to the access points. Cisco switches support a DHCP server option that is typically used for this capability. For more information about DHCP option 43, see the Configuring DHCP Option 43.
n DNS discovery—The access point can discover controllers through your domain name server (DNS). For the access point to do so, you must configure your DNS to return controller IP addresses in response to CISCO-CAPWAP-CONTROLLER.localdomain, where localdomain is the access point domain name. Configuring the CISCO-CAPWAP-CONTROLLER provides backwards compatibility in an existing customer deployment. When an access point receives an IP address and DNS information from a DHCP server, it contacts the DNS to resolve CISCO-CAPWAP-CONTROLLER.localdomain. When the DNS sends a list of controller IP addresses, the access point sends discovery requests to the controllers.
Deploying the Access Point on the Wireless Network
After you have mounted the access point, follow these steps to deploy it on the wireless network:
- Observe the access point LED (for LED descriptions, see Checking the Access Point LEDs ).
- When you power up the access point, it begins a power-up sequence that you can verify by observing the access point LED. If the power-up sequence is successful, the discovery and join process begins. During this process, the LED blinks sequentially green, red, and off. When the access point has joined a controller, the LED is green if no clients are associated or blue if one or more clients are associated.
- If the LED is not on, the access point is most likely not receiving power.
- If the LED blinks sequentially for more than 5 minutes, the access point is unable to find its primary, secondary, and tertiary Cisco Wireless Controller. Check the connection between the access point and the Cisco Wireless Controller, and be sure the access point and the Cisco Wireless Controller are either on the same subnet or that the access point has a route back to its primary, secondary, and tertiary Cisco Wireless Controller. Also, if the access point is not on the same subnet as the Cisco Wireless Controller, be sure that there is a properly configured DHCP server on the same subnet as the access point. See the Configuring DHCP Option 43 for additional information.
- Reconfigure the Cisco Wireless Controller so that it is not the primary controller.
Checking the Access Point LEDs
The location of the access point status LED is shown in Face of the 9105AXW and C9105AXWT Models .
Note Regarding LED status colors, it is expected that there will be small variations in color intensity and hue from unit to unit. This is within the normal range of the LED manufacturer’s specifications and is not a defect. However, the intensity of the LED can be changed through the controller.
The access point status LED indicates various conditions and are described in LED Status Indications .
Miscellaneous Usage and Configuration Guidelines
Using the Mode Button
Using the Mode button (see Ports and Connectors on the 9105AXW and C9105AXWT Models) you can:
n Reset the AP to the default factory-shipped configuration.
n Clear the AP internal storage, including all configuration files.
To use the mode button, press, and keep pressed, the mode button on the access point during the AP boot cycle. Wait until the AP console shows a seconds counter. Once the counter indicates the number of seconds the mode button is pressed, the AP status LED changes to blinking red. Then:
n To reset the AP to the default factory-shipped configuration, keep the mode button pressed for less than 20 seconds. The AP configuration files are cleared.
This resets all configuration settings to factory defaults, including passwords, the IP address, and the SSID.
n To clear the AP internal storage, including all configuration files, keep the mode button pressed for more than 20 seconds, but less than 60 seconds.
Note If the mode button is pressed for more than 30 seconds but less than 60 seconds, the FIPS mode flag is also cleared during the full factory reset of the AP. The FIPS flag when set disables console access.
The AP status LED changes from Blue to Red, and all the files in the AP storage directory are cleared.
If you keep the mode button pressed for more than 60 seconds, the mode button is assumed faulty and no changes are made.
Troubleshooting the Access Point to Cisco Controller Join Process
Note As specified in the Cisco Wireless Solutions Software Compatibility Matrix, ensure that your controller is running controller software release 8.10.105.0 or IOS-XE 17.3.x or later to support C9105AXW.
Access points can fail to join a controller for many reasons: a RADIUS authorization is pending; self-signed certificates are not enabled on the controller; the access point and the controller regulatory domains don’t match, and so on.
Controller software enables you to configure the access points to send all CAPWAP-related errors to a syslog server. You do not need to enable any debug commands on the controller because all of the CAPWAP error messages can be viewed from the syslog server itself.
The state of the access point is not maintained on the controller until it receives a CAPWAP join request from the access point. Therefore, it can be difficult to determine why the CAPWAP discovery request from a certain access point was rejected. In order to troubleshoot such joining problems without enabling CAPWAP debug commands on the controller, the controller collects information for all access points that send a discovery message to it and maintains information for any access points that have successfully joined it.
The controller collects all join-related information for each access point that sends a CAPWAP discovery request to the controller. Collection begins with the first discovery message received from the access point and ends with the last configuration payload sent from the controller to the access point.
When the controller is maintaining join-related information for the maximum number of access points, it does not collect information for any more access points.
An access point sends all syslog messages to IP address 255.255.255.255 by default.
You can also configure a DHCP server to return a syslog server IP address to the access point using option 7 on the server. The access point then starts sending all syslog messages to this IP address.
When the access point joins a controller for the first time, the controller sends the global syslog server IP address (the default is 255.255.255.255) to the access point. After that, the access point sends all syslog messages to this IP address until it is overridden by one of the following scenarios:
n The access point is still connected to the same controller, and the global syslog server IP address configuration on the controller has been changed using the config ap syslog host global syslog_server_IP_address command. In this case, the controller sends the new global syslog server IP address to the access point.
n The access point is still connected to the same controller, and a specific syslog server IP address has been configured for the access point on the controller using the config ap syslog host specific Cisco_AP syslog_server_IP_address command. In this case, the controller sends the new specific syslog server IP address to the access point.
n The access point is disconnected from the controller and joins another controller. In this case, the new controller sends its global syslog server IP address to the access point.
n Whenever a new syslog server IP address overrides the existing syslog server IP address, the old address is erased from persistent storage, and the new address is stored in its place. The access point also starts sending all syslog messages to the new IP address provided the access point can reach the syslog server IP address.
You can configure the syslog server for access points and view the access point join information from the controller CLI.
Important Information for Controller-based Deployments
Keep these guidelines in mind when you use C9105AXW series access point:
n The access point can only communicate with Cisco wireless controllers.
n The access point does not support Wireless Domain Services (WDS) and cannot communicate with WDS devices. However, the controller provides functionality equivalent to WDS when the access point joins it.
n CAPWAP does not support Layer 2. The access point must get an IP address and discover the controller using Layer 3, DHCP, DNS, or IP subnet broadcast.
n The access point console port is enabled for monitoring and debug purposes. All configuration commands are disabled when the access point is connected to a controller.
Configuring DHCP Option 43
You can use DHCP Option 43 to provide a list of controller IP addresses to the access points, enabling them to find and join a controller.
The following is a DHCP Option 43 configuration example on a Windows 2003 Enterprise DHCP server for use with Cisco Catalyst lightweight access points. For other DHCP server implementations, consult product documentation for configuring DHCP Option 43. In Option 43, you should use the IP address of the controller management interface.
Note DHCP Option 43 is limited to one access point type per DHCP pool. You must configure a separate DHCP pool for each access point type.
The C9105AXW series access point uses the type-length-value (TLV) format for DHCP Option 43. DHCP servers must be programmed to return the option based on the access point DHCP Vendor Class Identifier (VCI) string (DHCP Option 43). The VCI string for the C9105AXW series access point is:
The format of the TLV block is listed below:
n Length—Number of controller IP addresses * 4
n Value—IP addresses of the WLC management interfaces listed sequentially in hex
To configure DHCP Option 43 in the embedded Cisco IOS DHCP server, follow these steps:
- Create the DHCP pool, including the necessary parameters such as default router and name server. A DHCP scope example is as follows:
network <IP Network> <Netmask>
default-router <Default router>
<pool name> is the name of the DHCP pool, such as AP9105AXW
<IP Network> is the network IP address where the controller resides, such as 10.0.15.1
<Netmask> is the subnet mask, such as 255.255.255.0
<Default router> is the IP address of the default router, such as 10.0.0.1
<DNS Server> is the IP address of the DNS server, such as 10.0.10.2
The hex string is assembled by concatenating the TLV values shown below:
For example, suppose that there are two controllers with management interface IP addresses, 10.126.126.2 and 10.127.127.2. The type is f1(hex). The length is 2 * 4 = 8 = 08 (hex). The IP addresses translate to 0a7e7e02 and 0a7f7f02. Assembling the string then yields f1080a7e7e020a7f7f02. The resulting Cisco IOS command added to the DHCP scope is option 43 hex f1080a7e7e020a7f7f02.

The IEEE 802.11ax standard, also known as the High-Efficiency Wireless (HEW) or Wi-Fi 6, builds off of the 802.11ac and delivers a better experience in typical environments, and a more predictable performance for advanced applications such as 4K or 8K video, high-density high-definition collaboration applications, all-wireless offices and Internet-of-Things (IoT). 802.11ax is designed to use both 2.4Ghz and the 5GHz bands, unlike prior standards.
What is Cisco Multigigabit Ethernet?
Cisco Multigigabit Ethernet (mGig) is a unique Cisco innovation also available in the Cisco Catalyst 9105AXW series access point. With the increasing popularity of 802.11ax and new wireless applications, wireless devices now require more network bandwidth. Hence, there is a need for a technology that supports speeds higher than 1 Gbps on all cabling infrastructure. Cisco Multigigabit technology allows you to achieve bandwidth speeds from 1 to 10 Gbps over traditional Cat 5e cabling or newer. The C9105AXW AP supports up to 2.5 Gbps using mGig.
