Wifi connection drops when GPU is under heavy load

Hello there! I am hoping you can assist me with a technical issue that I have been experiencing. Whenever I run a heavy task on my GPU, such as training stable diffusion, my PCIe Wifi adapter becomes disconnected from the network. Of note I can still see available networks, but cannot connect to them.

I have a:

  • Gigabyte Aero 4080 RTX
  • Ryzen 7 3700X
  • GigaByte X570 AORUS PRO X570
  • Corsair HX850
  • G.Skill 32 GB DDR4-3200
  • SAMSUNG 970 EVO Plus, 500 GB SSD
  • Asus PCE-AC51 wifi PCIe
  • Router: Asus RT-AC66U B1 AC1750 Dual-Band WLAN Router

All with up-to-date drivers. The Wifi adapter is in the only other accessible PCIe slot, and I can connect to the wifi without any issues when I use usb-tethering with my phone. However, other devices on the same network do not experience any issues. Any suggestions or thoughts on how I can resolve this issue would be greatly appreciated. Thank you in advance!

My Guesses would be a driver issue causing a resource allocation issue if its not that the issue may be might be your motherboards stability on its PCIE lanes or interference from the new GPU.

I would try the following.

Update chipset and GPU driver, Clean install if you can take the time for the extra restarts.

If that does not work I would look at 

Try busting the GPU down to 8X speeds and Gen 3 in bios to check to see if it's more stable,, as that may help if it is one of the stranger resouce allocation issues. 


System CPU : Ryzen 9 5950 doing whatever PBO lets it. Motherboard : Asus B550 Wifi II RAM 80GB 3600 CL 18 2x 32GB 2x 8GB GPUs Vega 56 & Tesla M40 Corsair 4000D Storage: many and varied small (512GB-1TB) SSD + 5TB WD Green PSU 1000W EVGA GOLD

Thanks for the suggestions!


Noticed something while looking into your suggestion about the motherboard being the cuplrit: a mismatch in most recent chipset drivers on the download page (which were the ones I had) and the ones you can pull in through the app center from Gigabyte, the latter are more recent.


So far and a few hours into stressing the GPU with some more dreambooth training the wifi hasn't shown any issues. It is a little premature to call it fixed, but a good sign. (Will check back in after a few days
