I recently installed a new Win7 desktop for a client who lives in a senior living community. Connection is a cat5 feed to a d-link router-wi-fi and then cat5 to the wall. At first connectivity was fine, but on reboot, internet access stopped. In CLI, ping command resolves using DNS, but fails with "General Failure". Email and browsing also don't work. I disabled firewall and anti-virus, even took out the anti-virus program. I reconnected the old machine and found the same problem. I restarted the router (d-link wi-fi) and still no luck. What happened here? Is there something about this router I'm missing?
