I currently have an ap1200 with software version 12.2(11)JA3 installed. I am attemtping to upgrade via http to 12.3(7)JA3. The issue I get is - when in http upgrade, I click "browse" and select the .tar file then select "uprade" There are 3 internet explorer popups, a timer, one stating the progress, and a 3rd that says "Do not close this window...softwre is updating." After about 5 seconds, this window goes to the internet explorer error message of "Cannot display webpage" The error message on the ap is "HTTP INSTALL Error: firmware-var file_pathname not found" and "HTTP: error reading in file c:\c1200-k9w7-tar.123-7.JA3.tar"
Any help would be greatly appreciated.
