Software upgrades fail when you use the web-browser interface to install Cisco IOS Release 12.3(7)JA2 on 1200 series access points. The image size exceeds the access point's 4-MB restriction for software upgrades. Use TFTP to upgrade your access point to this release. For complete instructions on using TFTP to upgrade access point software
You can also install this release on 1200 series access points that have been converted to run Cisco IOS software. You can verify that an access point runs VxWorks or Cisco IOS software by looking at the GUI: the GUI on an access point running VxWorks has a yellow and red color scheme, and the GUI on an access point running Cisco IOS software has a green, light-green, and black color scheme.
To find the version of Cisco IOS software running on your access point, use a Telnet session to log into the access point, and enter the show version EXEC command. This example shows command output from an access point running Cisco IOS Release 12.3(7)JA2:
ap1200>show version
Cisco Internetwork Operating System Software
IOS (tm) C1200 Software (C1200-K9W7-M), Version 12.3(8)JA
Copyright (c) 1986-2006 by Cisco Systems, Inc.
On access points running Cisco IOS software, you can also find the software version 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 version appears at the top left of most pages in the web-browser interface.
Your 1200 series access point must run one of these VxWorks releases before you can convert to Cisco IOS software: 12.03T, 12.02T1, 12.01T1, 12.00T, 11.56, or 11.54T. If your access point runs version 12.04, you must downgrade to a supported VxWorks release before upgrading to Cisco IOS software.
The conversion upgrade image for 1200 series access points installs Cisco IOS Release 12.2(13)JA2 on your 1200 series access point.
