I purchased the Motorola MB8600 and was wondering if I made a good choice.
Currently I am running a Motorola SB6190 cable modem and a Asus RT-N66W/U and a Asus RT-AC66U.
I was using the RT-AC66U then when I tried to Upgrade it I bricked the router.
I managed to un-brick and am still using thhe RT-N66W/U
My goal is to have the perfect network running Tomato shibby with the absolute best router and modem were I don't have to keep buying new devices every 6 months.
I'm looking towered the future and plan on getting the 1GB-100GB internet connection and the fastest most reliable high speed wireless router.
What do you guy's think is a good combination?
