I bought a WIC-1ENET to go along w/ a 1720 router. I had a pretty late IOS 12.2(5) on it but then I plug it in, WHAM!!!
%PQUICC-1-UNKNOWN_WIC: PQUICC(0), WIC card has an unknown ID
I come to find out that only a FEW IOS'es support this interface. I looked up the WIC-1ENET on the configurator ... not a single thing mentioned about a particular IOS needed. Now I'm screwed because I'm not a CCO partner. I look REALLY REALLY bad.
This bites.
