I'm having a problem converting lwapp ap1231 to autonoumous mode. I followed all the steps on cisco docs, and also checked on other similar posts here on this forum.
First, I tried the tftp server with ip 10.0.0.10 set and tried to upload the image file "c1200-k9w7-tar.default". I held the mode until status went red and released and watched if it received image file from the tftp server but everytime it booted off with lwapp file. It's as if it never talked to the server at all. I changed several tftp servers, different file name and nothing worked out well.
So I moved on with using the wlc. I connected ap back to wlan and did "config ap downgrade...." and I received this error message "*Nov 12 15:32:06.737: lwapp_image_proc: unable to open tar file". I tried several file names ".default", ".tar" and kept getting same error message.
Please help me with this problem. Could it be the setting on the tftp server, corrupted tar files? I'm all out of idea.
I have the firewall disabled on my pc/tftp server and file entension is not hidden since I can see extensions on other files as well. I'm not sure about the file conversion. What I did was download the image file "c1200-k9w7-tar.123-7.JA2.tar" from cisco, and changed the file name to "c1200-k9w7-tar.default". I didn't do any extract/unzip though. Please let me know if I had wrong steps on the conversion part.
I had a similar problem before, not sure if it's the same thing you're hitting.
I renamed the file c1200-k9w7-tar.default but when I checked the TFTP directory the file was actually saved as c1200-k9w7-tar.default.tar - I used the command prompt to access the directory & manually rename it.
