I have a BEFSR41 Linksys Router and haven't had it for long. I tried to access the page today and was met by the box asking me for the username and password. The deal is, originally we set no username or password for the router, and everything I read tells me the default username and password is "admin". I typed these into the box, and it still claims it's the incorrect username and password. What do I do to access my router page if I can't even get past the username and password box?
