Can't think what else it could be. :(

I have already tried a null modem serial cable, it doesn't seem to work - no output. :( The same cable works fine with my 3com switches, and the method you recommended (2 PCs + terminal emulator). I also put together my own null serial cable together yesterday (and also reminded myself how bad I am at soldering in the process :P), but that didn't seem to work either. To me its starting to sound like the WLC is dead, although I can't find the beep codes that this WLC uses anywhere so I can confirm (it has two quick beeps, then a third beep after a few seconds). I'm not sure what else to try anymore. :(

I have tried with another cable with the same wiring, hasn't helped. :( Its really starting to sound like a dead WLC. :(

Before you give up, you might want to consider the possibility that the WLC's console has been set to some speed other than 9600 bps. I.e. you might try setting one of the other speeds: (tucson-wlc2006) >config serial baudrate ? [1200/2400/4800/9600/19200/38400/57600/115200] Enter serial speed.
