Supported Cisco Aironet Access Points
This release supports the following Cisco Aironet access points in autonomous mode:
Introduction
The Cisco Industrial Wireless Access Point is a wireless LAN transceiver that acts as the connection point between wireless and wired networks or as the center point of a standalone wireless network. In large installations, the roaming functionality provided by multiple access points enables wireless users to move freely throughout the facility while maintaining uninterrupted access to the network.
System Requirements
Cisco Industrial Wireless 3700 Series Access Point supports 64 MB minimum flash.
Finding the Cisco IOS Software Release
To find the version of Cisco IOS software that is running on your access point, use a Telnet session to log into the access point, and enter the show version EXEC command.
On access points running Cisco IOS software, you can also find the software release on the System Software Version page in the access point’s web-browser interface. If your access point does not run Cisco IOS software, the software release appears at the top left of most pages in the web-browser interface.
Upgrading to a New Software Release
To upgrade your access point or bridge software, follow these steps:
Step 1
Follow this link to the Cisco home page:
Step 2 Click Support and Learn.
The Support and Learn page appears.
Step 3 Under Find Product and Downloads section, enter the product name.
For example, enter 3702 in the search field. The Product Support page and Downloads options appear.
Step 5 Click Autonomous AP IOS Software.
List of supported release software download options appear.
Step 6 Download the selected software release.
For information on Cisco IOS software, click this link to browse to the Cisco IOS Software Center on Cisco.com:
Converting a Lightweight Access Point Back to Autonomous Mode
You can convert an access point from lightweight mode back to autonomous mode by loading a Cisco IOS Release that supports autonomous mode. If the access point is associated with a controller, you can use the controller to load the Cisco IOS release. If the access point is not associated with a controller, you can load the Cisco IOS release using TFTP. The image files and their supported access points are listed in Table 1 .
Disabling Radios to Prevent Unexpected Reboots When Upgrading the System Software
It is recommended to disable the radio interfaces before upgrading the software to prevent the access point from rebooting unexpectedly.
To disable the radio interfaces using the access point’s web-browser interface, which you can access through the access point's Ethernet port, follow these steps:
Step 1 Browse to the Network Interfaces: Radio Settings page.
Step 2 Choose Disable to disable the radio.
Step 3 Click Apply at the bottom of the page.
Step 4 If your access point has two radios, repeat these steps for the second radio.
Beginning in privileged EXEC mode, follow these steps to disable the access point radios using the access point CLI:
Enters interface configuration mode for the radio interface. The 2.4-GHz radio is radio 0, and the 5-GHz radio is radio 1. |
||
If your access point has two radios, repeat these steps for the second radio. Use the no form of the shutdown command to enable the radio.

Caveats
This section lists the Open Caveats and Resolved Caveats for access points and bridges in Cisco IOS Release.
Cisco Bug Search Tool
The Bug Search Tool (BST), which is the online successor to Bug Toolkit, is designed to improve the effectiveness in network risk management and device troubleshooting. The BST allows partners and customers to search for software bugs based on product, release, and keyword, and aggregates key data such as bug details, product, and version. The tool has a provision to filter bugs based on credentials to provide external and internal bug views for the search input.
To view the details of a caveat listed in this document:
1. Access the BST (use your Cisco user ID and password) at https://tools.cisco.com/bugsearch/.
2. Enter the bug ID in the Search For: field.
Note To have a Cisco User ID and password, you need to be a registered cisco.com user, To become a registered cisco.com user, go to the following website:

Important Notes
This section describes important information about access points and bridges.
Point-to-Point and Point-to-Multipoint Bridging Support for 802.11n Platforms
The point-to-point and point-to-multipoint bridging is supported on the 802.11n Cisco Aironet series access points. The 5-GHz bands support 20 and 40-MHz channel widths, and the 2.4-GHz bands support only a 20-MHz channel width.
The following items are supported on the 802.11n platforms for bridging:
- MIMO, short-range bridging (on campus or inter-building bridge deployments), with dipole and MIMO antennas (line of sight and short range) under 1 km.
- 20-MHz and 40-MHz 802.11n support.
- Workgroup bridge (WGB) short-range support.
- SISO (single-in, single-out), MCS 0-7 and legacy bridge rates (802.11 a/b/g and 802.11n) using one outdoor antenna.
Note This is only supported using short range links and is not a replacement for the 1530 and 1570 series access points which support bridging.
Low Throughput Seen on Access Points with 16 BSSIDs Configured
If your network uses 16 BSSIDs with 1 and 2-Mbps data rates, access points might experience very low throughput due to high management traffic.
802.11n HT Rates Apply Only to No Encryption or WPA2/AES Encryption
As per the 802.11n amendment, the 802.11n HT rates apply only to no encryption or WPA2/AES encryption. They do not apply to WEP or WPA encryption. If WEP or TKIP encryption is used, the access point and any 802.11n clients will not transmit at HT rates. Legacy rates (802.11a/b/g) will be used for any clients using WEP or TKIP encryption.
