Bests & Worsts Reviews from Amazon

I have had this modem for 3 months and it now locks up every 4-6 hours. I have to manually reboot the device to regain internet connectivity. I had my cable provider send a tech onsite to verify wiring and signal strength. With their equipment, there are no signal issues. When I put the Arris back online, they see errors coming from the Arris, and within 4-6 hours it locks up again. I contacted technical support and after a series of calls and troubleshooting steps, they agreed to send a replacement. With their standard replacement option, I have to ship my unit back, at my cost, and they will not send me the replacement unit until they receive mine. With their advance replacement options, I have to pay for them to ship the unit to me, as well as give them a credit card for the cost of the new unit, then ship my unit back within 15 days, again at my cost. Of course, there is no way I can do without a cable modem for Internet access, so I had to choose an advance replacement option and provide a credit card number for payment. Considering the cost of this unit, that it failed in just over 90 days, and is still within the warranty period, I am extremely unhappy having to pay for the shipping costs for both devices, on a warranty replacement. I am disappointed that Arris doesn't stand behind their products with a better warranty replacement policy.
