I have a Linksys model # wrt54gs. I installed it and everything worked fine, got everything set up too, it was nice. Then I got a new computer. I just hooked the router up and it worked. Then i tried to set up encryption and stuff. But when i typed in the routers ip addres i get page cannot be found. So i tried using the software cd that came with it. But it said the router was not connected to the computer. So i tried resetting the router but still neither option worked. The wireless and wired connections still work but i have no encryption and can't adjust any settings.
