WiFi disconnecting every few minutes on Linux Mint 20.1 RTL8822CE

[holwes]

I experience the same issue. When downloading a file or I heavily stress the network, the transfer stops. After some seconds, the download resumes, stops again and so on. Switch off the power management does not work.

Run following command.

Code: Select all

iw dev wlp1s0 get power_save

If output of command as following,

Code: Select all

Power save: on

Run following commands for disabling network manager's power management.

Code: Select all

echo -e '[connection]\nwifi.powersave = 2' | sudo tee /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

Code: Select all

sudo systemctl restart NetworkManager

An alternative for kelebek333's approach (there are multiple ways):

1. Check whether WiFi Power Management is "on" with:

Code: Select all

iwconfig

2. If "on", do this for turning it off (use copy/paste for transferring this complicated command to the terminal):

Code: Select all

sudo sed -i 's/3/2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

You can use copy/paste like this:

3. Reboot.

As I already wrote, turning off the power saving doesn't work.

As a quick troubleshooting step till someone else replies, boot up into Live Mint and see if the same thing happens.
Post back with the result.

As I already wrote, turning off the power saving doesn't work.

You should be more precise in your information.

"Switch off the power management does not work" can also apply to general power management for the entire system. In fact, that was what I presumed that it meant.

You should have stated that "Switch off the power management for the WiFi chipset does not work". Which would have saved kelebek333 and me some time and effort.

@holwes, If you install rtw88 module from this source , uninstall it with following command.

Code: Select all

sudo dkms remove rtlwifi-new/0.6 --all

Then, You can try to install HWE kernel 5.11 with following command and reboot. This kernel has rtw88_8822ce driver by built-in.

Code: Select all

sudo apt update ; sudo apt install --install-recommends linux-generic-hwe-20.04-edge

---

If the issue is not solved with newer kernel, You can try to install the rtl8822ce-dkms package with the following commands from PPA repository. Then reboot.

Code: Select all

sudo add-apt-repository ppa:kelebek333/kablosuz
sudo apt-get update
sudo apt install rtl8822ce-dkms
