Periodic WiFi shutdowns

Support Network
1

Hello! I’ve been having problems connecting to my 5G network ever since I got my new PC. Formerly I used an TPLink Archer T9UH, but I changed it for an ANDDEAR - MT761003, since it has native kernel support according to this. However, I’m still getting disconnects and “this device has limited connectivity” warnings when using my 5G network. I’ve tried deleting the network through

sudo nmcli connection add type wifi ifname wlp4s0 con-name wifi-auto ssid "Network_5G"
sudo nmcli connection modify wifi-auto wifi-sec.key-mgmt wpa-psk
sudo nmcli connection modify wifi-auto wifi-sec.psk "password"
sudo systemctl restart NetworkManager

And still no avail. I’ve checked via journalctl -fe and every time I get the warning I get the following output:

Those “CRTL-EVENT-BEACON-LOSS” apparently have something to do with distance optimization as stated here, though I’m not sure how to implement the fix (and I’m not sure that’s the problem I have anyways, since this is a desktop). I’m at a bit of a loss on what to look for or do next, so I’m recurring to you.

Maybe the PCIe card is running interference with the Anddear dongle? I was thinking on just buying a small router and just plugging it into my PC via ethernet cable as a sort of antenna, but I’d rather exhaust other options before I do that.

Quite often you need to run the latest kernel for get the adapter working properly.

I suggest you switch to Linux 6.15 then retry the adapter.

I just tried that, but it fails to start Plasma and I can’t get it to run through the command line (ctrl+alt+F2). I returned to 6.12.

That is what it looks like to me.
They are both up - and first, wlan1 (Meme_5G) is set as default, then wlan0 (Meme) is also set as default.

To add/use these driver options, create a file in /etc/modprobe.d/ with content:
options driver_name the_options_that_you_want_to_set

(three columns: 1) the keyword “options” 2) the driver name 3) the options
The name of the file is not important, but has to end in .conf)

Try this first, mac randomization and power save use to be the main cause of wifi disconnections:

Hi @TrpBandit ,

Can you tell us why you are using two wifi adapters at the same time?
I wonder whether you could disable the one you do not want and try again.

Regards,

Tried disabling wlan0 by

if=wlan0
sudo ip link set $if down

Still nothing, still get the multiple “CTRL-EVENT-BEACON-LOSS” error.

In part as a backup since I’ve had trouble getting the 5G connection to work so I figured it’d be at least nice to have something to fall back on, though mostly because I’m rather hesitant to disable it via CLI or similar since I’m a bit paranoid.

Tried it, lost connectivity still :confused: . I’ll try a live image to see if it’s because of something I did before getting the dongle.

Oh, I almost forgot: It’s not the wifi itself. I can use my cellphone as an antenna via USB tethering and it works as it should.

Hmm - but according to your log,
wlan1 reports a beacon loss - not wlan0

… you shut down the one which didn’t report a problem … :man_shrugging:

It may be the driver of the card used to connect to that wifi - as you suspected.
The other end of the connection may still work just fine …

wlan0 is the PCIe one, which has no 5G capabilities. I want to fix the dongle since it can connect to the 5G network. I can get a connection just fine with wlan0, but it’s slow as snails (in comparison).
