Why can't I edit the settings on my router?

So I just got a new FiOS router and everything set up just fine. There's a wee bit of an issue, I can't login to the IP or change the settings. The IP is the default 192.168.1.1 and I can get onto the log in page but it won't let me log in. I set the username and password for it, I've reset the router at least 3 times now. I understand that the extra characters that show up are worst security feature ever and I just ignore it but I type in the password exactly as I typed it when I set it and it tells me that I used the wrong password. If I do get past the dang login, I get a connection time out if I try to change anything, even if it's been less than 30 seconds since I log in. I can't do anything; I can't log in and if I do, it times out before I can change the settings.
