Archer TX3000E 5GHz Link speed is limited to 173/173 Mbps
I just installed a brand new Archer TX3000E NIC. While it is working ok, my 5GHz link speed is limited to only 173/173Mbps. I've tried using a different channel and channel width but it is still limited. My router is the Archer C60 AC1350 so I'm sure it is capable way more than this.

If I connect to the 2.4 GHz wifi, my link speed is actually more:

When I use my Archer T4U, the linkspeed is very good:

I'm using the latest intel driver not the microsoft one that comes from windows:

The location of the router and my pc is right next to each other and there is nothing in between.
Thank you for your assistance.
