Recently my house was struck by lightning. It was really damn loud, I dont think it was a direct hit, but at least one of my electronics got fried--my cable modem. Some surge protector. Anyhow I got a new cable modem today. Its a motorola sb5100 surfboard cablemodem. The problem is it no longer works with my D-link DI-604. The router is incapable of renewing the IP address. If I hook up the modem to an individual computer, however, it works like a charm. I dont think road runner has gone as far as to release router-resistant modems, and I also dont think my router was struck by lightning (it still lights up and accesses the computers fine.) Does anyone know what I should do? I already e-mailed D-link but that will take a few days and they'll probably send back pushover advice.
