WiFi network disconnects automatically & no WiFi networks are visible in Ubuntu

WiFi issue on Ubuntu resolved

This post is relative to all the novice as well as seasoned users on laptop specially — considering Lenovo and Dell. The common issue that I’ve heard from my friend is that my laptop connects to the Wifi fine, but after sometime it disconnects automatically, again during the same time no WiFi networks are visible in the scanning list. Also side-note:- all the software’s and drivers are up-to-date here.

Some logs seen are:

Here are the logs:

rtw_8822be failed to read ASPM
rtw_8822be failed to power on mac
rtw_8822be failed to poll offset=0x5 mask=0x2 value=0x0

Laptop model: Lenovo Ideapad

WiFi adapter: Realtek

Solutions:-

Wifi power setting ubuntu

may can try changing the power management mode of in the Network Manager here

/etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

from 2 to 3, so that it looks like this:

wifi.powersave = 3

Also, check if there is a UEFI update for your laptop.

Note:- I do not think you need to change the default kernel right away. You may toy around with UEFI and kernel if you wish but if something breaks then you should be able to fix it on your own.
