I am having a problem with a 1601 Router. The line protocol goes up and down. I installed another WIC 1T to test if the problem was on the Existing WIC but still have the same problem with the new one.
The IOS version running is 12.0 (3)T . Also when i use another Router on the same Link, it works fine, this means the link is ok, the problem must be with the router.
Anyone knows any known problems with 1601s with IOS 12.0 (3) T ? Help highly appreciated
