I have the 2801 router with a VIC3-2FXS card that is not detecting, I see it with sh diag command like Unkown WAN card.
The IOS that I´m using is:
Cisco IOS Software, 2801 Software (C2801-SPSERVICESK9-M), Version 12.4(15)T7, RELEASE SOFTWARE (fc3)
System image file is "flash:c2801-spservicesk9-mz.124-15.T7.bin"
I checked the details and It can support it.
Do you have any idea what I can do ?.
Thank you, best regards.
