Weird wifi disconnection issue with specific network

randomuser

Hi all! Recently I started to have a weird wifi issue. Basically after the boot, system connect to a wifi but then after sometime it disconnects and not only fails to connect again it stops seeing any wifi networks and only reboot helps to fix it (restarting NetworkManager changes nothing). Now to the most weird part:

It happens only with a specific (home) network. I tried many others and don't have any issues.
The issue started to manifest itself only recently, the same network worked well before
No other devices, including other laptop with Solus on it, have this issue

Any tips on how to fix it or at least find out the root cause? My main concern here is not the disconnect itself but the fact that it basically kills wifi until reboot.

Thank you!

I did have similiar issue months before. What ended up being the problem is the the wifi card I use. Switching to cheap usb wifi dongle fixed it. I am not sure if it is also your problem, but if you have usb wifi dongle lying around, try it.

Solus Budgie: i have the same issue!
if i leave the laptop switched on during night (with Firefox browser running), the wifi disconnects and does not show any wifi networks anylonger. as if the network-applet crashed.
only reboot helps.
but it does not happen every night. rather randomly: maybe one or two times a week.
i believe this happens since i had done all of those updates where the "/usr Merge" failed, and also another laptop feels slower (needs more resources?) since then.

I experienced a very similar problems a short while back.
Pressing restart on my WiFi box fixed it.
Never complain about WiFi until you have tried turning it off and on again.

BTO It might be worth checking your power settings. Some machines just don't wake up so well after sleep/hibernation.
On my own laptop I would sometimes loose all WiFi networks which could sometimes be fixed by turning off the laptop WiFi but other times only from a reboot. Also I had set my DNS server to Quad 9 in System Settings, the settings would suddenly change or not apply at boot (confirmed by using Quad 9 connection check) After rebooting my modem all of that works properly now, so a good place to start.
I have seen issues where WiFi security keys are very long or use non-standard characters.
Neighbours WiFi broadcasting on the same channel can cause unexpected behaviour.
The frequency that your machine is receiving WiFi can cause problems, 2.4Ghz has a longer range but a lower speed and 5Ghz returns higher speed at the cost of a reduced range. Being in a 'bad spot' in the house can cause your WiFi card to toggle between the two which will also make reception slow or non-existent.

Thank you for the replies! But unfortunatelly I don't think they're much applicable to my issue. As I say it only happens with one particular network and it only started to happen recently (and I'm on the same spot near the router). Also I don't think it's related to /usr merge issue as I did the update only after the issue was fixed and also I didn't have any problems after said merge.
For the reference the router is Asus TUF-AX3000 V2 running in dual-band (2.4GHz and 5GHz) with smart connect enabled. I think it started to happen when I changed a setting (completely unrelated to WiFi and later I reverted it back) and rebooted the router. But it also can be after some Solus update.
Possibly there are actually 2 separate issues here:

Either router or wifi controller (MEDIATEK MT7922 for the reference) is dropping connection
This particular kind of connection drop somehow puts wifi controller in some unrecoverable state

Obviosly I'm more concerned with the second part but I'm also interested to know what is so different with that network.

randomuser Install lshw from repo
Run (sudo lshw -C network) while its working keep copy -Run it again when it stops working
and see what it says about wifi then.

From the details in your first post, if the affected computer does not have similar problems on other networks then it sounds like there is a specific interplay between the settings on the router and the hardware of your PC.
If you can, try setting the router back to default values which is an easy way to eliminate one half of the puzzle.

Both outputs are identical

randomuser Thats good then.
I would then prob try (sudo journalctl -b 0 -u NetworkManager) when its
not working see if something show up.

Have you checked when wifi crashes does bluetooth still work? (If you can)
