IOS backup and Upgrade for Cisco Aironet APs

IOS Version 1130-k9w7-mx.124-10b.JA needed Internet Explorer version 6 for web configuration.

I obtained an AP-1242AG with a later IOS version 1240-k9w7-mx.124-21a.JA1. Checking the release notes for this version revealed that Firefox browser was now supported.

I then obtained a copy of 1130-k9w7-mx.124-21A.JA1 to upgrade my 1130.

Firstly I backed up the existing IOS to my tftp server using a console connection:

#archive upload-sw  tftp://

Then I uploaded the new IOS to the AP:

#archive download-sw /overwrite tftp://

Next a reload and a show version to verify the correct version.

And finally, check the browser interface with Firefox.

Aironet version check with Firefox
