SOLVED: GPU under load turns off Wi-Fi adapter

[KarmaKelevra]

SOLVED: The faulty Wi-Fi card was causing the issue. Got new card and had no issues.

 

Hello there,

 

I have just built a new pc and run into a very weird issue. I have Wi-Fi/Bluetooth extension card in PCIEx1 slot. Anytime GPU goes under load gaming/stress test (Total War: Warhammer/AMD Adrenalin) my PC loses Wi-Fi connection and can't find any networks, Bluetooth is working as usual. The issue still persists after closing the game/stress test and only restarting PC restores the connection (sometimes with extra restarts, windows troubleshooting), other devices connected to the same network have no issues.

 

Things I've tried so far:

1. Re-installing latest Wi-Fi drivers - 22.150.0 for Intel Wireless adapter
2. Installing Wi-Fi card into the PCIEx1 slot above (closer to GPU) - that made it worse,  couldn't find any network even after restarting.
3. Updating BIOS to the latest version - 2803
4. Updating GPU drivers - 22.6.1
5. Disabling Bluetooth on extension card
6. Disabling "Allow the computer to turn off this device to save power"
7. Disabling "Ultra High Band (6GHz)"
8. Lowering transmitting power from Highest to Medium-High
9. Setting Channel Width for 2.4GHz - from auto - to 20MHz
10. Setting Channel Width for 5GHz - from auto - to 20MHz
11. Setting Channel Width for 6GHz - from auto - to 20MHzo
12. Changing HDMI/DP cables
13. Disabling "Radeon Chill"

System:

• CPU: AMD Ryzen 5600X
• CPU cooler: DeepCool K400
• MB: ASUS B550-A (BIOS: 2803)
• SSD: WD_BLACK 1TB SN750 SE NVMe
• Memory: TeamGroup DDR4 2x8GB - 3200MHz - installed in 2nd and 4th slot
• GPU: PowerColor - Red Devil AMD Radeon RX6700 XT  
• PSU: EVGA Supernova G+ 750W gold
• Wi-Fi card: Fenvi FV-AXE3000 AX210NGW PCI-E - based on Intel(R) Wi-Fi 6E AX210 160MHz - installed in the 3rd PCIEx1 slot, at the very bottom of the motherboard
• Case: 4000D Airflow
• Windows 10 x64 v.21H2
• No OC - just DOCP to enable 3200MHz
• PC is 3 days old and stable so far, no crashes/freezes/lags.Temps are stable CPU: <70C, GPU <78C during stress tests.
• Router: Netgear Nighthawk R6700 - AC1750 - is in another room

 

I am really at a loss here and would greatly appreciate any help and recommendations. Please let me know if there is any additional info will be helpful.

Seems you think this is a possible power draw problem.  You’ve got a lot of PSU though, so if it is a power problem it could be the motherboard.  The whole thing seems a bit unlikely though.  Maybe check the contacts on the card and slot

All of your PCI-E 1x slots are managed by the Chipset, can you try to update the BIOS, be very careful when updating the BIOS to read all BIOS update changelogs as some BIOS require certain versions of the Chipset drivers or first update to some BIOS ver before first then to that one and of course don't lose power in your house or brick the MOBO.

 

Can you check Event Viewer on your PC if any usual error regarding the slot itself or the card?

This either smells like Chipset issue on MOBO or Windows being crap itself with drivers or managing the card.
