Hi all.
I have a weird PPP CHAP problem and was wondering whether anyone could help me. Basically I’m trying to connect a Cisco 1841 to a DSL circuit provided by Claranet inthe UK. The problem is that the router fails to authenticate thus the circuit never comes up [Vi2 is in up/down state]. Now here is the interesting part, if I copy the config [see below] from the 1841 and paste it on a 837 the 837 can authenticate successfully and I am able to use the circuit fine.
I also checked the WIC-1-DSL chipset and noise levels and all seems to be fine on both routers. Could this problem be related to an IOS issue?
Thanks in advance
