Wifi disconnects randomly

laosom · 17 November 2020 13:08

My wifi connection randomly drops when in Manjaro KDE when the 5.4 LTS kernel is loaded.
I only experince this with Manjaro KDE, not with other distros .
When it brakes it displays a KDE popup window , asking for the password.
It seems kernels 5.8 and 5.9 does not produce this .
My wifi router is set to use atomatic for channel select.

I found only these related so far:

t/wifi-connection-randomly-disconnects/35520

Please advise

I checked also the arch wikis

https://wiki.archlinux.org/index.php/Network_configuration/Wireless
https://wiki.archlinux.org/index.php/wpa_supplicant

and found this:

Password-related problems
wpa_supplicant may not work properly if directly passed via stdin particularly long or complex passphrases which include special characters. This may lead to errors such as failed 4-way WPA handshake, PSK may be wrong when launching wpa_supplicant.

In order to solve this try using here strings wpa_passphrase <<< “” or passing a file to the -c flag instead:

wpa_supplicant -i -c /etc/wpa_supplicant/example.conf

In some instances it was found that storing the passphrase cleartext in the psk key of the wpa_supplicant.conf network block gave positive results (see [2]). However, this approach is rather insecure. Using wpa_cli to create this file instead of manually writing it gives the best results most of the time and therefore is the recommended way to proceed.

I use the option "Store password for this user only encrypted " in KDE Wallet.

Hi @laosom,
Please post the output of the following command in the terminal: inxi -N.

Regards

laosom · 19 November 2020 15:51

Hi j8a

I tried with the recommended configuration in /etc/NetworkManager/conf.d/wifi_rand_mac.conf
but wifi breaks with the same errors.

lali@dell6540-manjaro:~$ inxi -N
Network: Device-1: Intel Ethernet I217-LM driver: e1000e
Device-2: Intel Centrino Advanced-N 6235 driver: iwlwifi

laosom · 19 November 2020 16:02

I am testing this on 2 laptops. On another one it disconnected onyl once if I remember correctly.

That one is:

[lali@latitudee6500 ~]$ inxi -N
Network: Device-1: Intel 82567LM Gigabit Network driver: e1000e
Device-2: Intel WiFi Link 5100 driver: iwlwifi

Althouh I am unsure if it is really kernel related,
the annoying is, that kernel updates in the 5.4 LTS series do not make any difference or fix.
I did not experince it with 5.7 5.8 5.9 kernels so far, but I wonder what is wrong with it.
Ubuntu based distros are fine with 5.4.
I even tried to create additional users to be sure the kde config files are not messed up,
but I am unsure about the results. It seems more stable though.
I haven’t tested it with my original user and not encrypted password (clear text ).
I would like to understand the wpa errors and the possible fixes.

Hi, @laosom
Please, can you check from the terminal that the linux-firmware is installed on your system?
sudo pacman -Qi linux-firmware
The output may look like this:

Just in case either you have no output or it is not installed run the following command on the terminal:
sudo pacman -S linux-firmware

Hope it help, regards

Hi @laosom,
I read the wiki Arch posts and I suggest you to consider the following:

Create an wpa supplicant interface with:
sudo wpa_supplicant -i -c /etc/wpa_supplicant/wlp3s0.conf

Then, with a text editor open example.conf and write the text.
network={
ssid=“MISZTI”
psk=“I do not know your passphrase”
}

Save, and rerun wpa_supplicant.

Hope it helps, regards

laosom · 30 November 2020 17:05

Hi Javier,

Would you explain why that would help ?
I use NetworkManager and KDE wallet to store the password ecrypted.

Hi, @laosom
Please, take a look at this post.

Maybe, you could find the answer to your question reading the wiki archlinux posts.
