I have a Cisco 1720 router with an WIC-1ENET card for the WAN connection.
I can't get the WIC-1ENET card recognized.
There are no bootup messages indicating a problem.
It's installed in Slot 0
I follow the instructions on configuring the card and go to the global configuration mode. Then go to
enter "interface Ehternet 0" and I get an unrecognized command response.
The documentation says I need IOS 12.1(3)XT1 or latter. In the show version command on the router it displays 12.1(3) only with no other letters.
How can I get an upgrade if I need it. If that's not my problem what is it?
Thanx.
