I have a customer that is running a Cisco 871 router. This has been in place for abotu 6 months. Last week they started to have some Internet problems. I have narrowws the problem to a DNS issues, SSH, RDP, etc work while browsing does not. Browsing goes down for a few minutes at a time multiple times a day. I have changed DNS servers, and we still have the same issue. The ISP says its the Cisco, and that is really the only thing I have not removed from the loop. Any ideas?
