Review on 🔌 Renewed ARRIS SURFboard SB6121 4x4 DOCSIS 3.0 Cable Modem - Fast Internet Connection for Home (Black) by Joel Payne

The modem worked fine for a couple of weeks until it ran into some problems that required a reboot. Then the modem started disconnecting and reconnecting and throwing critical error codes in the device log. After a 2 hour phone argument with Arris and my cable provider, they (Arris) finally relented and sent me a replacement while my product was still under warranty. Not only did the product not last (83 days), Arris as a company completely lost my business. On top of the mostly terrible customer service, I was charged an upfront replacement. Not only do they save my credit card info to ensure they get the failed device, but unless you want to go a few weeks without a modem or buy or rent another to use in between, you have to pay them a fee to ship another device . If the replacement eventually fails, I'll buy another company's modem. I suggest that you do the same at first.
