I have this AP displaying red-green-red. No IOS found. I have the hostname as "ap :". We were changing the IOS. I had to change the filename for my TFTP server to work. My partner left the filename as "file.tar" as the destination filename. I'm assuming this is why we can't boot. We're trying to access the flash directory to change the filename but we are having no luck. Are we on the right path? Thanks in advance.
