Hey there folks! I may have a solution for the dropping of the Ethernet ports. I’m gonna paste in the solution. I say ‘solution’ as it has worked for me and I’ve been testing it for the last 2 hours. For reference I’m running Ubuntu 24.04.3 LTS. After launching STEAM and installing OR launching a game of significant size the heat would rise from the CPU and GFX card causing me to lose both my Ethernet ports. Only had WIFI would continue to operate. The only fix until now has been to shut down the computer and unplug power for about 30 seconds.
Try this… open up terminal in your Linux
STEP 1 — Edit GRUB boot options
Open the GRUB configuration file: sudo nano /etc/default/grub
STEP 2 — Modify the kernel command line
Find the line that looks like this: GRUB_CMDLINE_LINUX_DEFAULT=“quiet splash”
Change it to: GRUB_CMDLINE_LINUX_DEFAULT=“quiet splash pcie_aspm=off”
⚠️ Do not remove quiet splash. Just add pcie_aspm=off inside the quotes.
STEP 3 — Save and exit
In nano:
Press CTRL + O then
Press Enter then
Press CTRL + X
STEP 4 — Update GRUB
Apply the change: sudo update-grub
You should see output showing your kernels being updated.
STEP 5 — Reboot sudo reboot
STEP 6 — Test (Important)
After reboot:
Confirm Ethernet is working
Launch Steam
Launch any game
Play for a few minutes
Exit the game
Expected result:
Ethernet stays connected.
No disappearance. No Wi-Fi fallback. No power-cycle required.
Now I’m not running Windows 11 but I’m sure there is an equivalent. I hope this works for you.
After applying the fix I loaded and ran Cyberpunk 2077 High demand graphics. Played for 40 minutes. No drop. Then loaded Diablo4 also high demand graphics. played it for 30 minutes. No drop. Shifted to Fallout 76 and played for about 30 minutes - no drop.
Let me know if this helps! I was afraid with the issues I wouldn’t be able to run any AI projects. That’s my next test.
Good luck!
