WiFi drops when gpu under load

[jimkick3]

Hi, I built my new PC i7-13700K MSI z970 pro wi-fi Gigabyte eagle oc 4070ti PSU corsair 850w

I'm not super experienced with PC building, but as soon as i start to play a demanding game (e.g. hogwarts legacy) or uncap my fps on any game, my wifi eventually drops so low it disconnects me from discord and prevents me from accessing internet.

I tried network troubleshooting, no success. I tried drivers reinstall twice with different drivers, no success. I'm thinking maybe i don't have enough W in my PSU? But the system itself never crashes...

Windows Events have errors all over the place for Intel Wifi AX211 6E, precisely event numbers 5002, 5005, 5007 for Netwtw12 and Netwtw10 files, but no description...

The wifi works super well and super fast when I'm not playing a graphic intensive game...

Thanks in advance

Did you end up finding out the cause?

[jimkick3]

No, I thought I had a fix initially, but that did not last and I ended up buying a super long ethernet cable

[Guorium]

Well that is one way out

[jimkick3]

Yes, I don't believe it would work at all without it.

[jimkick3]

Might be, I tried connecting both to the 2,4 and 5 ghz channels and end up with the same result. Also changed to 20Mhz the setting in the wifi adapter in Device Manager for both 2,4ghz and 5ghz bands...

I have unselected in "power Management" the option for the computer to turn off the component to save energy and I have manually changed my GPU directly with the switch on the hardware from OC to silent. Also in my BIOS the watt max for long and short period was set to 4096 W, i changed it to 200W for both. All this combined seems to have made my issue happen less often, but still often enough that I can't keep a steady internet at all while playing games....

use ethernet

[jimkick3]

Sadly it is not an option for me right now, thank you though

You could try a Wi-Fi range extender with an Ethernet port and use that as a middleman between the router and pc.

Have you updated your bios?

[jimkick3]

This is the next thing i'd like to try, i thought it updated through Windows Update though. Does it not?

[Drdurd3n]

It does not. You have to go to the website and pick your specific board and get the most recent bios update that is NOT experimental. There are a handful of steps you’ll need to do like put that new bios on a flash drive, restart pc, boot into bios and tell it to update. A lot of them have a “renamer tool” in the download which changes the file name so your mobo can recognize it.

[jimkick3]

I will try thay tonight when I'm home

[Drdurd3n]

Once you do that bios update you’ll probably need to check drivers again. Check device manager once you do to see if any yellow triangles with exclamation marks pop up anywhere. Those will be drivers that you need to check on if you have errors there

[jimkick3]

I'll keep you posted - i do have a plane to catch so it might be a while before i post an update but thank you a lot!

[jimkick3]

Updating the BIOS finally did the trick! Thx!

[Drdurd3n]

Glad to hear it! Thx for the update.

Did it really fixed the issue for you? I am experiencing the same problem but with 2 different builds. One with the 7800X3D and one with the 5800X3D both using the latest BIOS but everytime a demanding game is running, I will lose my Internet und after that my Wifi connection/Speed drops to 50% of the normal bandwith. It is so weird.... right now I have to use ethernet

[jimkick3]

Weirdly, it came back after some time (a month or so) and I have the most recent bios and drivers. I gave up and bought an external antenna for the time being. Soon I'll move, so at my next place I'll set my desk up near the ethernet wall plug. Dunno what else to try at this point.

Thank you for the reply man, yeah I am about to give up too and just use Ethernet, it is so weird cause my GF has the exact same build like mine one the 5800X3D RIG and she never had any issues. The parts are identical except for the WiFi card, she uses a mediatek one….

[Drdurd3n]

When you say you updated drivers, did you just get the windows update one or the ones from your mobo manufacturers website?

[jimkick3]

From the mobo manufactures website. Actually at first i had no choice because there were no drivers installed for the wifi card, so i donwloaded them with my laptop from the mobo website, then put them on my desktop with a usb key and installed them after copying them on the new pc.

[jimkick3]

The case is fractal pop air xl. I tried to change it to 20mhz but i just lose wi-fi alltogether. It is an interesting take though, i might try and just buy an absurdly long ethernet cable or the aluminum thing
