Title:
Wifi crashes on 20.04 on Lenovo Legion Y530
Status in Ubuntu MATE:
New
Status in linux package in Ubuntu:
Incomplete
Bug description:
After upgrading Ubuntu Mate to 20.04 , my wifi crashed on Lenovo legion
Y530. The strange thing is that it connects to the network, i have internet for
some time (usually between 1 and 10 minutes) and then it disconnects.
After that, the applet shows me something like device not ready and i can
only restart the computer to connect. Then it crashes again...
I also tried a fresh install with the same results.
I used 19.04 and 19.10 on the same laptop as my primary operating system and
wifi worked flawlessly.
Since I do my work on this laptop i was forced to downgrade back to 19.10 for
now.
This is my lshw -C network (from 19.10 If I remember correctly it was
RTL8822BE also in 20.04)

If you think it is necessary, I can try to install 20.04 on an
external hard drive and give you some more info from there.
