So first I did a dumb thing and I know this. I was upgrading the images on the router to the latest and greatest and also wanted to upgrade the AP inside it. I wasn't paying attention to the fact that the new AP image was LWWAP rather than autonomous which is was before. well long story short the AP is now nonfunctional and I can't even seem to get into anymore.
at first I was able to get into the unit using the "service-module wlan-ap 0 reset bootloader" command then doing "service-module wlan-ap 0 session". I wanted to wipe the flash and start over from scratch so I erased the flash and set the environment variables to my network and was able to tftp the autonomous image ( ap801-k9w7-tar.124-10b.JDA3.tar ) back to the flash. After doing that though the ap will no longer let me connect to it.
router1#service-module wlan-ap 0 session
Trying 192.168.10.99, 2002 ...
% Connection refused by remote host
I tried issuing the "service-module wlan-ap 0 reset bootloader" command again with no luck I get the same connection refused.
At this point I am at a loss on how to restore service on this thing without having a true console to it.
If anybody has any suggestions on how to fix this I would be grateful.
router#service-module wlan-ap 0 session
is equivalent to
which in other words is just a reverse telnet to the 881's internal IP address, and out its (internal) line 2.
So if you get "% Connection refused by remote host" when you try it - then this almost surely just means that line 2 is left in some busy state.
router#clear line 2
Should fix the problem for now.
As to why you got into this state ... I assume that there was a previous session left lying around.
