I am having trouble with my router's administrator password. I'm using a Belkin F5D7234-4. I just bought the router, logged into the router using a blank password. Then I changed the administrator password. When I log out and try to log back in it keeps telling me the password is invalid. I've hard reset the router and tried again about 10 times now. I don't know what it's changing my password to when I change it, but it's definitely not what I type in. Anyone had this problem and know how to fix it?
