Purchased this modem 4 months ago and it worked perfectly until “I moved it on the shelf.”  Seemed to go into a standby mode - has power but does not receive internet signal or reset when I tried to do that.  Called cable company to check it out, tech said it’s a modem problem and recommended I purchase an SB6190 DOCSIS 3.0 Cable Modem (which I just did).  My question ~ will ARRIS allow me to return it, and refund me for this defective modem? (I sure hope so.)  Not having internet, because of this defective modem, has put me in a difficult position as I work two days at the office, and three days from home.  

Usually its an exchange, not a refund. You can contact support and try and find out


I would suggest visiting www.arris.com/consumersupport for further assistance regarding warranty claims.


Glad to see your post to know we’re not alone - been a fan of arris for YEARS. Just bought one of these this summer for my daughter and it died today. When I lookup the serial it lists the warranty as expired on the date I bought it. Five months old and it’s dead. None of the other networking equipment plugged into that ups is broken so I can only assume the modem failed. Only path to try to get warranty honored? Pay for support; no. Thanks. 
I’m so sad to see arris quality and support tank like this. If my home or business modem fail I’ll be looking elsewhere.

best of luck to you!


@J-S if you have proof of purchase from an authorized retailer, you can always contact warranty. 

to often people buy from unauthorized sellers
