I have two computers hardwired with the wireless Linksys -G router and a Dell Inspiron E1705 laptop. I had the network set up and all was fine. My wife got a prompt to upgrade explorer to 7.0 and now the laptop will not connect. When I try to highlight my home network and click repair, it states that if cannot find my IP address. How do I get the Dell wireless card to read the IP address? I tried resetting the cable modem and router but to no avail. I'm extremely new to networking so any help would be greatly appreciated.
