The Archer T9UH should be able to do at least 1300/162 Mbps (or 324?) right? But I can only get 1300/54. It doesnt say in the specification list on official site, only mentions transmit speed?

I can't find any other info that says its limits in this regard. I've spent countless hours troubleshooting over ther last couple of days. Drivers, websearching thing after thing, disconnecting all other wireless devices, configurations and options for this device and the router, nothing has helped. Maximum signal quality is indicated. I've tried different channels, auto and manual selections. etc etc. Im on win 10 pro.

But before I go replacing/firmware the router, I'd like to know if this is just the limit of this devices connection, 54Mbps receive/upload, even when at the full 1300Mbps transmit/download? This wouldnt make much sense to me and would be a shame because a faster recieve was the reason I bought this adapter, upgrading from a 433/54 adapter.

Also if anyone has advice on anything I havent tried it would be appreciated. Yes... I've turned it off and on again... many times lol. Thanks in advance for any help.
