Kubuntu keep log me off my wifi

[Deadly_cry]

Hi,

Before starting I want to tell you that I'm french so excuse my mistakes ^^

 

Since maybe 5 month, kubuntu log me off my wifi at random times. Sometimes every day, sometimes after 2-3 days. By log off I mean just disconnecting me and putting a logging prompt. If I ignore this prompt, i can simply click connect without reentering my password and the cicle continues (the same appen if i reenter my password).

Since I'm a linux noob I'm realy confused with this and google isn't realy helping so if any of you have the solution for this it would be amazing.

I realy need a stable connection since I use this pc as both a game server and a NAS, you can easily see why getting disconnected at random isn't realy practical here ^^'.

What's your WiFi module?  If you're on a laptop, what model is it?

 

Can you run this command on the terminal, and paste the output here:

lshw --short

One other thing I want you to check is if you can open your KWallet.

Can you tell me its name and if it's currently open?

 

Also, try to reset your WiFi ("forget" the connection, then set it up again.)

[FUIT1985]

You just need to enable the wifi interface from the command line. Then you can use it from the graphical interface of your desktop environment.

 

Type the following command to see the name of the wi-fi interface installed on your computer:

$ sudo ip link show

By default, the kernel attributes generic names such a eth0 (for wired Ethernet) or wlan0 (for WiFi) to the network interfaces.

 

Then you can activate the wifi interface with the following command:

$ sudo ip link set wlan0 up

* Obviously you have to replace wlan0 with the name of your wi-fi interface.

Wouldn't that imply that his WiFi was down?

 

The issue is that he keeps getting kicked out.

If he is able to connect to the internet, the wi-fi interface has the necessary modules to connect.

So the problems could be due to:
excessive distance from the modem routers; obstacles; etc.

Traditionally, however, it happens that the interface is disabled by the inexperienced user. So checking the status of the interface is a good idea. In any case, I do not recommend installing proprietary drivers for the wi-fi interface.

It is also necessary to check the configuration of the modem router and if a time limit has been established for the connection of a user or client.

About this, I know for sure It's no a signal issue since I can connect to my wifi from a lot further than where my server is, it's also not a obstacle issue because I only have like 2 thin walls that the signal need to go trough (I'm getting full strengh on the server, with 300mb/s which is the same as my PC that do not have this problem). It's also not a modem router issue, this disconnecting only appen with my server and within all of the options of my router, I never saw something about time limits for connections.

Ok so I run the command, seemed to work, at least I didn't get an error message. Am I done? Did you just fixed month of pain in one command x)?

Through google searchs I saw a lot of people talking about power saving mode causing this but all off their fixes never worked, but none of them used this specific command, so I'm hopping that you'r a genius ^^.

you can update your system to lock your configuration with the following command:

sudo apt-get update && sudo apt-get upgrade && sudo update-initramfs -u && sudo update-grub && sudo reboot

I marked it as a solution too soon.

After some days I got disconected again, but this time I took a picture of the thing showing up:

 

Traduction (at least the best i can do lmao): Dialog box of wifi password - KDE Daemon

Please provide the password for the wireless network "pifree"

 

Pifree is my wifi network. When this show up, I'm disconected. Don't know why. Now I'm sure it's not a power saving thing because on top of the commands you made me run, this time I had a discord bot running in background, doing stuff with the network every minute.

The "dormant" mode is the power saving of Wi-Fi interface . Could you repeat the command:

$ sudo ip link show

I need the output of the above command.

Thank you.

Got this:

 

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp3s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc fq_codel state DOWN mode DEFAULT group default qlen 1000
    link/ether d8:5e:d3:52:d9:f0 brd ff:ff:ff:ff:ff:ff
3: wlp1s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DORMANT group default qlen 1000
    link/ether 5c:a6:e6:c6:04:4f brd ff:ff:ff:ff:ff:ff
 

[EDIT]

 

wlp1s0 is the interface used for my wifi network:

Have you performed a system update these days?

Not since you made me do one after we thought we fixed it

[FUIT1985]

cd /etc/network/ && ls

I need the output of the above command.

Thank you.

You need to check the configuration file of your WiFi interface (if it exists) and why "dormant" mode is automatically enabled. Then you have two options:
1) you can write a configuration file for your wifi interface with execute permissions to disable "dormant" mode;

2) or you can manually enter the

$ sudo ip link set wlp1s0 mode default

command when the problem arises.

The first option requires that I verify the contents of your directories and of your configuration files (including the output of the cat command) and you may unintentionally share your Wi-Fi password.

If i pay attention I think I can avoid sharing my password, and I do share it i can switch it before anyone reading it can fly to france and use it x). So I'm gonna go with the first option (if you'r ok with it obviously) since if I understand correctly it's the only one which should (keyword should) prevent this forever

Living in France does not provide security. The configuration files of your network services may contain sensitive data such as your static ip. In order to carry out a spoofing attack, an attacker (for example a neighbor, an ex friend, an ex wife, etc.) who knows you are using this site could take advantage of the above information.

You should learn how to configure network services yourself. I could be a cracker who uses social engineering to pretend to help you and then attack you instead.

Sorry for security reasons I prefer not to go any further.

I understand, I mean i know what is a static ip and things like that I was just making a joke, but I don't know what those wifi config files look like so I guess it's safer not send anything ^^. Could you tell me where I need to look on my file system to find this file(s) so I can take a look and maybe find the solution?

There is a free French manual (the author is French) and it deals with debian jessie. Instead, the debian buster edition by the same author is in English.

Both manuals explain the basic commands, the configuration of interfaces and network services.

In short, how to use the command line.

I actually gave you the solution. Find the configuration file that enables "dormant" or power saving mode by default. I use the nano program as editor. It is easier for me than vim.

find, | , xargs, grep ... Could they be useful for a search?

NetworkManager Workaround to turn off Wi-Fi power saving mode

sudo apt-get update && sudo apt-get upgrade && sudo nano /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

if you find this:

[connection]
wifi.powersave = 3

You need to change the 3 value with 2

So, actually with this (or if you don’t find anything enter the content below):

[connection]
wifi.powersave = 2

In order to save this file with nano

ctrl + O

In order to exit from nano

ctrl + X

After you need to set the permissions and … reboot

$ sudo chmod 755 /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf && sudo ip link set wlp1s0 mode default && sudo update-initramfs -u && sudo update-grub && sudo reboot

After reboot you can check the status (and mode) with:

$ sudo ip link show

 

You’re welcome.

 

Quote

Linux distinguishes between administrative and operational state of an interface. Administrative state is the result of “ip link set dev <dev> up or down” and reflects whether the administrator wants to use the device for traffic.

However, an interface is not usable just because the admin enabled it - ethernet requires to be plugged into the switch and, depending on a site’s networking policy and configuration, an 802.1X authentication to be performed before user data can be transferred. Operational state shows the ability of an interface to transmit this user data.

Thanks to 802.1X, userspace must be granted the possibility to influence operational state. To accommodate this, operational state is split into two parts: Two flags that can be set by the driver only, and a RFC2863 compatible state that is derived from these flags, a policy, and changeable from userspace under certain rules.

The above commands permanently disable both the power saving operational state (RFC2863) and the power saving administrative state of the Wi-Fi interface "wlp1s0" (RTL8812AE) with "DORMANT" mode.

-- snip --

There is no reason to upgrade your system, regenerate grub, and regenerate initramfs every time you make a change...

 

Also if it's a power management issue, which is fairly common on Realtek WiFi modules, linux-hardware db shows it uses the "rtl8821ae" module.

You can disable power management with

echo 'options rtl8821ae ips=0 fwlps=0' | sudo tee /etc/modprobe.d/rtl8821ae.conf
reboot
