user_9umpnm If you connect a different router to a network and set it up to work with a modem it would work just fine if that is what you mean. A gateway however is both a router and a modem, and you would need to replace both to have a working connection. As long as that device is listed on your account with us, and active you could use it in place of our gateway as well. However, to get a device added to your account and active requires access to the account.
