Is there a specific network module that a wic-2a/s needs to go into to be recognized on a 3640. Ive tried every version IOS that says it work, verified the operation of the wic-2a/s in a 1720, and verified my network module with a wic-1t. The network module that I have is a an NM-1E2W. Do I need a different module for the wic-2a/s Ben PS, debugging assembly takes way longer than debugging C. __________________________________________________ Do You Yahoo!?
