WIC-1AM-V2 Not Working With IOS

Unanswered Question
Jul 14th, 2008

The IOS upgrade on our 1841 routers from image

c1841-advsecurityk9-mz.124-9.T3.bin to c1841-advsecurityk9-mz.124-15.T5.bin appears to

cause problems with the WIC-1AM-V2. After the upgrade I get a line of garbage when

attaching to the modem. Is this a known issue and is there a firmware update or

configuration change that will resolve the problem?

I have tested this out on several routers that have different running configs. Also

swapped a couple modem cards out to make sure it wasn't hardware related. I then noticed

by reverting back to the old IOS they all started working again. I can only assume there

is some firmware update needed, a config change, or this might be a IOS compatibility


I have this problem too.

Currently have an open case. Just wondering if anyone else has experienced this?

Press on the TAC to have the problem reproduced.

At that point they will open a bug and eventually it will be fixed.
