The default regular expressions for username and password can be found here:
https://github.com/apache/guacamole-server/blob/787ae317fc2da932cd826c9df68932355258dd60/src/protocols/telnet/settings.h#L58-L68
The password regex should already match the password prompt you have there. If your router doesn't support the standard telnet mechanisms for sending the username (forcing Guacamole to rely on a regex for that, as well), that may be why you're seeing things fail. The default username prompt regex used by Guacamole looks for "Login:" or "login:", not "Username:".
