Paul's UVerse router is starting to get finicky, so he got a new one and wants to use the old one in bridge mode, but it won't work. It keeps asking for a password. Leo says it's unusual for a factory to set a router with a password from default. The password should be in the manual. Paul should try doing a factory reset.
Leo thinks that the IT guy that Paul used pre-configured it with his password. So just hitting the hard reset button for about 10-15 seconds until the lights start blinking will completely wipe out any previous settings and put it back to its factory default settings. After that, if there's still a password, try "ADMIN" or "admin."
