Archer T9UH v2 - Only connects at 600mbps
I've had a few disconnects and also I have speed concerns. I expected this to connect to my TP Link Wireless Router (TP-Link AC5400) at something better than 600mbps. The router is in the very next room (very close, just the other side of the wall).
I could swear it used to connect faster than this. I have no explanation for the change. Any recommendations for what I should do?
(I did use the drivers posted on the TP Link site for Windows 10 x64)
