Cisco806, slow bandwidth problem

[romebaby]

I just configured and installed an 806 behind my cable modem and my bandwidth dropped from 100+ Kb to around 10. I'm also getting a lot of late collision errors when I surf. My cables and NIC are good, I had a netgear rp114 and had no problems. Any suggestions? (the CCIE at Cisco support couldn't figure it out). Thanks in advance.

Talk to your ISP about the duplex and speed settings. Manually bias your interface to match thier settings. Late collisions are almost always related to half/full duplex mismatches. The autosense feature of Cisco isn't very good. I doubt seriously you were talking to a CCIE. Let us know how that pans out.

Thank you Scott!! My nic was set to 100 and my modem was at 10. I changed my nic to 10 and problem solved. I guess I was too into the router config and overlooked the obvious.

Always glad to help.
