Can't find saved wifi network at the start of the day

General system Kernel & Hardware
1

Since (maybe) after the latest lts kernel update, I’ve run into this weird problem. I can’t find the last used wifi (which has been running continuously) after I turn on the laptop in the morning. The wifi reappers and connects properly if I turn the router off and back on. I’m not facing any such problem on my other devices. Also, I can’t easily reproduce this problem; if I turn off the laptop and turn it on again after some time, this problem does not occur. It only occurs when I turn on the laptop for the first time in the morning.

Here is my system info:

In this timeframe, I turned off and on the wifi a few times, turned on and off the airplane mode a few times, and rebooted the machine once.

Hello,
does your laptop discover any other networks and you just can’t see yours or does it not show any wifi networks at all?

3

It shows every single one except the one I use.

4

How do you usually check for your WiFi? With the systray nm-applet? Is it also not showing in the network configuration when you open it through the settings? Can/Did you try to connect via cli? Here is a instruction on how to use wpa_supplicant with cli:
https://wiki.archlinux.org/title/Wpa_supplicant

NetworkManager is a frontend and it would be able to use different backends. In your case and by default it’s wpa-supplicant. I think it’s necessary to figure out which of these is the problem.

My first thought was a power saving problem or something like this. But if all other networks are shown, your WiFi module is probably not in power saving mode.

5

I use kde’s default wifi widget, and the wifi does not show up in nmcli dev wifi either. In system settings it just shows up as a a saved network. I will look at the arch wiki tomorrow morning when the problem occurs again and report my findings

6

Another tought on this:
Do you have any other devices in your WiFi that have the same issue (not permanently connected devices)?
That’s just to make sure it’s not related to router settings e.g. for non-accessability for certain times of the day in the router firmware.

7

So just a while ago the connection randomly disappeared while I was using my laptop, and it also disappeared from my android phone. I’ve connected to another wifi.
Also, wpa_cli is spamming <3>CTRL-EVENT-BEACON-LOSS every second now.
Is my router the culprit? I’ve been using it for three years without any issue

8

The CTRL-EVENT-BEACON-LOSS spam lasted for a good 15 minutes before finally stopping, but my wifi hasn’t reappeared on laptop or my phone.
edit: Tried connecting through cli and failed.

@afschy
Have you tried turning off your router for a few minutes then start it again and wait until it’s fully synced. Then check your WiFi to see if it is working. (shown)

10

I think so. Your laptop’s wifi chipset seems to work and if you have the same or similar issues with your phone it all points towards the router.

Can you check the router’s settings in regards of power saving or accessability restrictions? Maybe you could also check if there is a firmware update available or whether the firmware got updated recently.

11

Well it does work, I wrote it in my original post. I was trying to understand if my laptop is causing the problem, since I won’t be able to restart my classroom’s wifi if it happens during class :")

12

I’ll look into it. Thanks.

13

Check if there is a Bios update for the laptop.
