So I am looking into replacing my families home modem (Arris TM722 leased by Comcast) with the Arris SURFboard SB6190. I have never replaced a modem before. Should it go smoothly? Just unplug it, take out the battery, disconnect all the cables, put in the new one, connect all the cables, put in the battery and plug in the power and then follow included directions to call Comcast and activate it? The odds of complications, of things not going cleanly and requiring troubleshooting low?
