Intel AX210/AX211/AX411 often loses access to hardware device

[k20shores]

After I boot up Ubuntu, I often lose wifi within 10 minutes. This happens because the wifi device cannot get access to the wifi hardware (see the dmesg log). Windows is installed on another NVME


What I've tried:

• sudo vim /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf and set wifi.powersave=2
• Disabling a iwlwifi driver (still disabled)
• Disabled fast startup and hybrid shutdown in windows
• When the wifi fails, restarting the network manager (sudo systemctl restart NetworkManager.service). A little red icon with a white bar appears in place of where the wifi symbol is and no output is printed to the terminal and still no wifi
• Updating my BIOS
• Installed the Intel® Wi-Fi 6 AX210 160MHz driver from this site, though it appears a different driver is still in use (specifically ty-a0-gf-a0-83.uc)

Not sure what else to do. Here's a pastebin of the wifi info

• When it works
• When it doesn't work
• And a dmesg log of when it has failed

Edit /etc/default/grub and add

pcie_port_pm=off pcie_aspm.policy=performance

so it looks

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pcie_port_pm=off pcie_aspm.policy=performance"

Save and exit then

sudo update-grub

Reboot
