solved Intermittently wifi doesn't work Mint 20; no problems LMDE 4 [Ralink RT5392]

Post by urdrwho »

I'm also having a wifi issue with mint 20 but not LMDE4.

When using Mint 20 I'll sit down at the computer and see that I have no wifi. It is intermittent.

Yesterday I used LMDE all day and let it run all night. In the morning I still had wifi.

This morning I started Mint 20 and within a few hours I come back and see that wifi is absent.

Below is what took place during my time away and when I returned and re-started wifi. Also I just ran iwconfig and inxi -Fxxxz

If it was happening on LMDE4 I would think hardware but I do believe this is a Mint 20 OS issue. This never happens when I am using the computer but only seems to happen when the computer is in idle state.

Oh an BTW I have /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf set to wifi.powersave = 2

Re: Intermittently wifi doesn't work Mint 20; no problems LMDE 4 [Ralink RT5392]

Post by urdrwho »

Yesterday I ran LMDE4 all afternoon and let it run all night. This morning wifi is still up and running.

Now I'll go start Mint 20 and see how long wifi stays up. The trouble is it is intermittent so it could take time.

Is the inxi query in the original post taken when running LMDE or when running Mint20? Whichever it is, please post it for the other OS so we can compare them.

Yes first one is Linux Mint 20 Ulyana base: Ubuntu 20.04 focal and this one is LMDE4 using 10.2 buster. Hm? I thought Debian was up to 10.5? Anyhow here it is for LMDE4

Not sure if there is much interest here but again I lost wifi on mint 20. Again I come down in the morning I have no wifi and I don't know why? Turn mint 20 wifi off and on then immediately I have wifi.

I'm going to use LMDE4 for a day or two and see if it happens on there.

From the lack of ideas it seems that either:

A: Few people have this issue
B: Nobody knows how to fix it

Two days of watching and this is all I got. So far my wifi has been solid.

Code: Select all

I did three things:

1. This computer can only do 2.4 off the router so I changed the 2.4 from 20 mhz to 40 mhz with auto channel
2. I changed /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf from 2 to 1. One is default
3. I changed /etc/NetworkManager/conf.d [ifupdown] from false to managed=true

Code: Select all

[main]
plugins=ifupdown,keyfile

[ifupdown]
managed=true
# managed=false

[device]
wifi.scan-rand-mac-address=no
I won't mark solved for a few days but so far so good.
