I have a Intel Lan adapter on my ROG strix b550-a mb that failed and won't assign an IP address.  

Bought a TP-Link tx201 pcie card that worked for 4 weeks then randomly stopped while I was working.  

I've done absolutely everything I can, aswell as my tech remote accessed my laptop and tested the modem and also the PC, tried to assign static IP, a whole lot of other stuff and still no success.  It's communicating properly but just will not assign an IP.

Reformatted twice yesterday to no success.

Even allowed access to the computer from router through QoS, nothing seems to work.

I know my mobo has 3x revisions for the onboard lan adapter and assuming it's cooked.  But the new pcie card now does the same thing.
