I am getting a hard time to enable wifi on legion 530 with Ubuntu 20.04.

Things I tried so far,

sudo tee /etc/modprobe.d/blacklist-ideapad.conf <<< "blacklist ideapad_laptop"
rebooted

I could see wifi enabled but it was not able to detect any available networks.

Then I tried:

echo "options r8822be aspm=0" | sudo tee /etc/modprobe.d/r8822be.conf
sudo rmmod r8822be
rmmod: ERROR: Module r8822be is not currently loaded

I would really appreciate any help.

Details: OS: Ubuntu 20.04 Wifi: Realtek r8822be Laptop: Lenovo Legion

I have even tried following steps but that didn't made any difference

git clone https://github.com/lwfinger/rtlwifi_new.git

cd rtlwifi_new
git checkout extended
make
sudo make install
sudo modprobe -r rtl8822be
sudo modprobe rtl8822be

NOTE: Things worked perfectly over Ubuntu 18.04

I have Lenovo Ideapad 530S, after upgrading to Ubuntu 20.04 from 18.04 WI-FI stopped working.

This post helped me: https://askubuntu.com/a/1271087/972111

sudo apt install build-essential git
git clone https://github.com/mid-kid/r8822be.git
cd r8822be
./make

remove the misbehaving rtw88 module


sudo rmmod rtwpci rtw88


install the r8822be module


sudo ./make install
sudo modprobe r8822be
sudo reboot

I have a Lenovo Ideapad, Ubuntu 20.04.03 LTS with 5.11.0.27 kernel using a PCI Realtek 8822be Wi-Fi/Bluetooth adapter.

I tried Bulat's driver fix above, but it did not work long term. Finally I found a post that suggested turning off Wi-Fi power control using this command:

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

and that did the trick.
