Greetings! After purchasing 4 of the Cisco Aironet 1200 G Series WAPs, I'm now running into a slight issue with them.
I received these last week with the understanding that if I didn't have the Cisco controller device, I could convert them from being the Lightweight Access Point, back to Autonomous mode with an IOS.
With this, I checked the documentation that came with the device and found the "Upgrading Autonomous Cisco Aironet Access Points to Lightweight Mode" or http://forum.cisco.com/eforum/servlet/NetProf?page=netprof&forum=Wireless%20-%20Mobility&topic=Getting%20Started%20with%20Wireless&needs_authentication=yes&CommCmd=MB%3Fcmd%3Dadd_discussion%26mode%3Dshow%26needs_authentication%3Dyes%26location%3D.ee7c7c3.
From there, I followed the instructions listed under Converting a Lightweight Access Point Back to Autonomous Mode. Before the rename of the file, I checked the device and found AIR-LAP1242G-A-K9 for the Model No.
One of the Cisco Certified admins here was able to obtain the latest build for the IOS for the device or c1240-k9w7-tar.123-8.JEB1.tar. Per the instructions, I renamed the file to coincide with the model of the device.
I followed the instructions from there, and it looked as if everything was going well. However, after the upgrade, I'm running into an issue with the following:
File "flash:/c1200-k9w7-mx.123-8.JEB1/c1200-k9w7-mx.123-8.JEB1" uncompressed and installed, entry point: 0x3000
At this point, the device just locks up. All lights are lit green on the device. According do the documentation, it should reboot and from there, I should be able to access the web interface by IP.
I've tried to perform the upgrade again using the same IOS build, but the same thing happens with the lock up.
At this point, I'm assuming the issue is with the build of the IOS that I have and I may have to look at getting an older build. However, before doing so, I thought I would post something here to see if anyone had an idea.
I may have needed to refine my searching of the forums, but wasn't able to find anything in relation to my issue. If there is something out there, I do apologize for the post and will happily refer to any current information.
If you need any further information in relation to this, please let me know. Any assistance is greatly appreciated. Thank you!
