Does anyone else have this wireless card/adapter? (TXE75E)

I run Windows 11 and i'm connected to 6G WiFi through a TP-Link AXE16000 quad band router.

I am a little upset so far as I installed the card, downloaded the latest drivers, ran multiple speed tests just to hit peak speeds of a whopping 94 mbps. (Note: we have Windstreams fastest internet plan) and my computer is literally one wall away. 

My son reaches speeds averaging 350 MBPS (highest I seen was 780 mbps for him) and he is probably 25 feet from the router.

I spoke with TP-Link tech and they can not find the issue either. They want to access remotely, but i thought I'd jump in here and see if anyone could help first.  Please note my son's computer and mine have similar specs.

Can anyone help on this? I am not understanding what is impacting such slow speeds. It's annoying after spending $500 for a router, and then another $60 for a wifi card. I mean, the cheap $12 wifi usb dongle I had plugged in was hitting speeds of 50-70 mbps.  

Something isn't right, but I can't figure it out. 

Any help is appreciated,
