I am extremely disappointed with the RT-AC68U. I have only had it for a few days and it was rebooting for no apparent reason and would freeze often and was not accessible without power reset. It was running extremely hot with two wireless connections streaming 40-60Mbps a piece. The menu/software isvery slow to update setting adjustments.
This was my first Asus networking experience. I only chose it because it was in stock and the Nighthawk was not. The lan throughput was a positive point and I did reach 149.8 Mpbs throughput to my ISP's local test server which is higher than 148.1 with my previous router a Netgear AC1750 R6300 v2.
Asus support had me update to 205 firmware, which made the router even more problematic.
Wan to Lan performance was very good.
Not reliable. Crashes often.
Runs very warm.
UI is slow and sluggish
Tech support is terrible, for Europe anyway. I could not understand the man. Very heavy accent and not friendly.
I join a long list of unhappy customers of this router it seems. I will return it today for a full refund and hope to find a Nighthawk locally.
