Question PC stopped connecting via 5GHz

[ScottForum]

All of a sudden, my main PC has lost its ability to connect to my router via 5GHz. I can connect via 2.4 just fine. Other devices in the house have no problems connecting via 5GHz.

I have tried the following...

• Rebooted computer
• Rebooted router
• Disabled 5GHz, rebooted router, re-enabled 5GHz
• Changed IP of PC, rebooted router
• Completely reset PC networks, ie. dns flush, reset winsock, release/renew ip, rebooted.
• Uninstalled adapter from Device Manager, including driver. Re-connected and re-installed fresh, latest driver.

My WIFI adapter: TP-Link WiFi 6 AX3000 PCIe WiFi Card (Archer TX3000E)

Is it possible for a wifi adapter to lose the ability to connect via certain frequency?

TP link... I love them and I hate them. How old is the card, They sadly have a high failure rate but TP is good about replacements.

I bought it about 5 months ago. It is possible for the card to flake out connecting to a specific frequency? I'll contact them to get feedback. Thanks for the input.

They are known for the 5g band to die in my experience.
