Wireless network randomly unavailable

[noobcoder]

Hello guys,

Over the last few weeks my wireless network has been randomly shutting off and showing up as unavailable. Restarting my laptop usually works (although within the past few days I've needed to do it more than once to get it working). Its frequency was tolerable until a week ago, but it's not now. I did try solutions for the related questions on this forum but they didn't work for me.

What does this show:

 iwconfig 

[sleeper12]

You're also using the unsupported 5.0 kernel. Update to the 5.4 kernel.

So my connection is currently working but here's the output

iwconfig

lo no wireless extensions.

Ok, see if the 5.4 kernel helps.

[noobcoder]

Hi, so I did update to 5.4 but upon doing that, my wifi was permanently unavailable so I downgraded back to 5.0.

[sleeper12]

That's strange, not sure why the 5.4 kernel would be a problem on that newer machine. You could try the 4.15 kernel. Or, maybe try a live session of Mint 20.1 & see if wifi works better for you there on the 5.4.

[sleeper12]

Another thought, be sure secure boot is off. Check:

 mokutil --sb-state 

[noobcoder]

It is, also I installed virtualbox recently, could that be causing any issue by any chance ?

I'll try that, thank you.

I'm not sure about that. Are you dual booting with Windows?

[noobcoder]

No, windows in VM though

[sleeper12]

Ok, I'm not familiar enough to know if that would be a problem.

[sleeper12]

I know that in dual booting with Windows, fast boot & fast startup can cause wifi problems. Whether that means anything here, I don't know.

Ok the 4.15 kernel didn't work for me, it just showed a black screen.
20.1 had the same issue for wireless as in Mint 19
Also, my driver manager just shows this.

Not sure if this has any effect on the OP's problem or not,
but with my WiFi Hotspots, they go to sleep after a period of time.

I have to open a new tab and look for a different URL,
and then it wakes up, and all is well provided we keep accessing it regularly.
