My father has a Linksys WRT54GS router at his house. He had his desktop PC rebuilt (hdd apparently crashed, I'm not so sure but he lives far enough away that I have to trust his "pc guy at the computer store" ). Anyway...he had the desktop rebuilt, couldn't remember the WEP key to get on his wireless connection. He logs in to the router and gets the default router page. He clicks on ANY of the links in there - to see status, to change wireless settings, anything, and gets 'Page Cannot Be Displayed" as if the router isn't serving up the page. He is connected directly to the router (cabled to his laptop). He has not upgraded or attempted to upgrade the firmware. Additionally, a firmware upgrade to resolve this problem is not possible as he can't get to any of the pages in the router that would let him do that. He's telling me he changed nothing on his laptop. I had him clear his browser cache and temporarily lower the security settings in his browser. I've googled around to find the answer to this and have come up with nothing. Anyone have any ideas of what else to check/do, or should we just replace the router? Thanks.
