Arris is going to  send me a new unit, but here’s the catch: for no cost. I can send my defective modem back and in 7 to 10 days. I will receive a new one. Since internet service is as vital as any other utility in this day and age, a 10 day delay is not really a good solution. For $20 I can hold onto the defective modem and wait for a new unit to arrive in seven days and then send the defective one back.  For $25, same story,  but the new unit will arrive in five working days —-for those in the back of the class —-seven days and five working days are the same number of days. For $50 I can get a replacement unit overnighted to me.  This scheme on its face looks like fraud deterrence, but it’s another unnecessary fee scheme. If Arris is worried about fraud, they would charge me a refundable deposit and overnight a new unit to me, refund the deposit after I send back the defective unit and they receive it.  All for a product that’s 100% under warranty and that went defective through no fault on my end. 

Or exchange it with where you bought it. 

Those fees are pretty standard practice if you’re wanting faster times. 

Or go pickup a new modem somewhere and use that and get your unit replaced and keep it as a backup

​@Vjordai Do you have G34 or G36?  The G34 doesn’t support 2Gig service and may be causing connectivity issues.
