Just upgraded to an AC68U router from the N66U.

The N66U was good enough to cover every room of my whole 12xx square feet condo, with about 1-2 signal bars at the lift corridor and stairs room (where I smoke and play with my phone). Router in the living room, and I could get a stable 144Mbps connection on wifi in my study room. Way better than my old TP-Link wifi router.

The AC68U is even better! 300Mbps in the study room, 3-4 signal bars outside, way stronger signal and speed in the home. Well worth the almost 1K price, imho.

Anyone in Penang want a 2 year old N66U for half price?
