I have a Dell 8250 with Windows XP Home providing internet access to an iMac running OS-X 10.2.8 via a Belkin router (F5D7230). The Dell is using Norton Internet Security 2006 for a firewall and antivirus software and accesses the internet via Comcast broadband and an external Comcast-supplied RCA modem.
This is the third Belkin router that I have had fail in two years. I just cannot believe that it is the router, that something else is causing this. (The first router worked for a year and then failed. The second router for 6-8 months, and then failed. The third router failed in only 2 weeks!)
When the router fails, neither the Dell nor the iMac have internet access. Sometimes I can restart the access by rebooting both the router and the modem by unplugging each. However, when I take the router off line (unplug it entirely from the system), I have no internet access problems on the Dell. When I include the router in the system, it works fine for a time. Then I lose internet access on both the Dell and the iMac.
What is going on? It just doesn't seem plausible that it's really been the router each time. Could it be the Norton interfering somehow (though it has not been the same version of Norton, even, this entire time)?
Any leads/suggestions are very welcome!
