I applied the fixes regarding power settings, kernel updates, system configs, still like nothing's ever changed.

Something is really messed up, what's interesting is that Bluetooth immediately interrupts the internet connection when connected to a device.

Did you blacklist rtw88_8821ce?

Try disabling ASPM. Add this to the kernel command line: pcie_aspm=off

By kernel command line, do you mean I should add it through the grub by pressing e and then editing ?

a-h-ismail commented 1 year ago

I think you can do it that way, but to make it permanent you should edit your grub config: sudo nano /etc/default/grub Add it to the end of the line starting with GRUB_CMDLINE_LINUX_DEFAULT, save the file then run sudo update-grub and reboot.

If you are on Fedora, you can simply add it using grubby: sudo grubby --update-kernel=ALL --args="pcie_aspm=off"

Thank you, I'll test it and see how it goes.. will try to report at a later time.
