Unreliable wifi on Ubuntu - RT3290 Wireless 802.11n 1T/1R PCIe
Dear Community,
I have an HP 4340s laptop, and have been using Ubuntu since 2013.
During the years I used mainly LTS versions though the symptoms I'm describing occurred on several version. I can't recall exactly though as far as I can, 14.04 LTS and 18.04 LTS were stable in terms of the wifi, though 17.10 and 19.10 were not. I hoped that going up to 20.04 LTS will solve this phenomenon again, though unfortunately it's not the case.
Issues:
1) wifi is working for a while then suddenly the Wifi icon turns to be a (?) - question mark - and no network is available
- workarounds:
- put wifi to airplane mode, and turn it again
- run this command: sudo ifconfig wlo1 down;sleep 5;sudo ifconfig wlo1 up;
2) GIVEN wifi is on, WHEN I power off the laptop it turns off THEN restarts in a couple second 3-4 sec
- workarounds:
- put wifi to airplane mode, and power off after this
- run this command: sudo ifconfig wlo1 down;sleep 5;shutdown now
I think the problem is around the wifi driver, though before I start replacing it based on random linux forum comments I though I summarize it here perhaps someone experienced the same.
Some details:

As I found 'driver=rt2800pci' is the open source driver and "is experimental"
I tried today:

Link Quality=44/70 Signal level=-66 dBm

Wifi seems to be stable for a while let's see whether it solves the random wifi drop issue or not.
However it does not solve the restart issue.
I welcome any idea around this.
