I have a problem with this issue. Dose WIC-2T(x 2) and HWIC-2FE(x 1) work together in the same C2821? Because when I installed the 2FE in to my router. Powered on, and the lights on the card are lit continuously, also the card is not detected in the router IOS. I have already installed two cards on this 2821 router(WIC-2T). Is there any limitation on these different cards?TKS!
You've just answered your issue. The HWIC-2FE doesn't work because you are using the wrong IOS version.
Please post the full output of these commands here:
