D-Link DIR-615 :: Error 322 - Can't Get Any Internet Access Through The Router?

I've had my DIR 615 router for quite some time. The hardware version is C1, firmware 3.01 originally. It's been fine for the most part (asides from connection issues now and then with the internet - which we rectified by unplugging modem and/or router). A couple nights ago we had a storm and the next morning the router would not connect to the internet. I tried unplugging the router and modem a number of times but could never establish a connection. The internet globe LED was originally orange but after I cut off the power, it never came back on. I tried a number of different cables between the modem and router and could not fix the issue. I bypassed the router totally and the internet works fine. After a lot of failed attempts, I decided to reset the router and reinstall it with the disc. I followed the instructions and kept getting error 322 that the router could not be found. I tried 3 different computers and 5 different wires to fix the problem but to no avail. I kept encountering the same error on each computer. Since the router can't be seen, I must bypass it totally to get any internet access so trying the online setup doesn't work because I can't connect to the router and then to the modem since there is no internet access. So now I'm stuck. I'm not sure if my router is damaged from the storm. All other lights work (LAN and wireless icon) but I can't get any internet access through the router. I'm not sure if I should just go buy another router or not. The installation checks out fine until connecting power to the router and then it can't be found.

I am running windows 7 and vista on different computers and laptops and used setup 4.1.7141.2
