Intermittent wifi disconnects

Hello,

My Wifi setup is like the following:
- I have a Ralink dongle on my desktop
- It is capable of 2.4 GHz
- Over a period of hours, I see multiple network disconnects that last a few seconds.
- I use NM and it uses wpa_supplicant I think
- The network disconnects show up in browser loading or gaming problems

I get the following errors.

```
Nov 11 01:34:45  wpa_supplicant[567]: wlan0: CTRL-EVENT-SSID-REENABLED id=0 ssid="EE-2CQ5HC"
Nov 11 01:34:45  wpa_supplicant[567]: wlan0: BSSID 60:8d:26:e9:aa:da ignore list count incremented to 2, ignoring for 10 seconds
Nov 11 01:34:45  wpa_supplicant[567]: wlan0: Removed BSSID 60:8d:26:e9:aa:da from ignore list (clear)

Nov 11 01:34:45  wpa_supplicant[567]: wlan0: SME: Authentication request to the driver failed
Nov 11 01:34:45  wpa_supplicant[567]: wlan0: Added BSSID 60:8d:26:e9:aa:da into ignore list, ignoring for 10 seconds

```

What is happening here ?

Please post the output of

find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-40s | %s\n", $(NF-0), $(NF-1)) }' | sort -f

What is happening here ?

The AP gets ignored, immediately un-ignored, the authentication fails (but apparently because your wifi NIC doesn't respond) and then the AP gets ignored again.
If it's not concurrent services, please post your complete system journal for the boot after such disconnects

sudo journalctl -b | nc termbin.com 9999

Do I need to disable the wpa_supplicant@wlan0.service ?

The termbin paste is https://termbin.com/a9e0t

Another part that bothers me is the following line.

wlan0: cannot understand ECSA IE operating class, 4, ignoring

Re: Intermittent wifi disconnects

Yes.
There're later connection issues but those might just be the AP being too annoyed by the clients behavior.

Sanity check: is there a parallel windows installation?
=> 3rd link below. Mandatory.
Disable it (it's NOT the BIOS setting!) and reboot windows and linux twice for voodo reasons.

Re: Intermittent wifi disconnects

There is no parallel Windows installation. I only have a linux installation.

I have removed the wlan0 service. I think there might be an issue with the driver but I could be wrong.

I got the following in the journal.

Is this related or a different issue altogether ? When I first saw it, I thought may be my driver version is old. I did an upgrade to latest but the issue persists.
