Tested 3 Arris routers and 2 Motorola routers.
All 3 Arris routers get 90k every 5-20 mins
Both Motorola routers never lagged out over once over 2 hrs.
Problem is the Motorola routers only support 100mbps and Arris gets me my full 300mbps.
Time warner is giving me 30$ of this next bill and said I should go buy my own router or downgrade to 100mbps.
