LinuxMint19 - Wifi often disconnect
Hello !
I have installed LinuxMint19 since two weeks and I noticed that wifi is often disconnecting.
This happens about every quarter of an hour, sometimes sooner.
To reconnect, I switch wifi off and switch again on. A few times, this manipulation does not work and I have to reboot my computer.
I don't know if it's related to this wifi problem but when I start the computer, it's written "error : cannot find the table of symbols, please type a key to continue ..."
Thank you for your support !
My system :
Linux Mint 19 Cinnamon 3.8.6
Linux core 4.15.0-20-generic
Processor : Intel© Pentium© CPU G3220 @ 3.00GHz × 2
Graphic hardware : Advanced Micro Devices, Inc. [AMD/ATI] Cedar [Radeon HD 5000/6000/7350/8350 Series] (prog-if 00 [VGA controller])

Re: LinuxMint19 - Wifi often disconnect
Hi, @francky
All the commands and code can be copied from this post and pasted into your terminal. Run this terminal command:
iwconfig
It will print two columns of information, much like this:
Code: Select all
enp6s0 no wireless extensions.
wlp9s0 IEEE 802.11 ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=0 dBm
Retry short limit:7 RTS thr:off Fragment thr:off
Power Management:off
lo no wireless extensions.
enp5s0 no wireless extensions.
wlp9s0
. You need to identify your device. While still in the terminal:sudo nano /usr/bin/wireless
Paste this code in and replace
wlp9s0
with the name of your device from above:Code: Select all
#!/bin/sh
/sbin/iwconfig wlp9s0 power off
sudo nano /etc/systemd/system/wireless.service
Paste this code in:
Code: Select all
[Unit]
After=network.target
[Service]
ExecStart=/usr/bin/wireless
[Install]
WantedBy=default.target
Code: Select all
sudo chmod 744 /usr/bin/wireless
sudo chmod 664 /etc/systemd/system/wireless.service
sudo systemctl daemon-reload
sudo systemctl enable wireless.service
sudo systemctl start wireless.service
iwconfig
. It should tell you this:Power Management:off
All of the above commands and code set your wireless device into full power mode. That should stop the disconnections. If it doesn't then we'll need to know more about your machine so please post the output of this terminal command:
Code: Select all
inxi -Fxz
[ⅽode]
and [/ⅽode]
code markers by selecting </>
from the mini toolbar above the textbox where you type your reply. Note that it's a capital F
in that command, followed by lower case xz

Re: LinuxMint19 - Wifi often disconnect
Hi catweazel !
I do not have a /usr/bin/wireless folder or file on my system !
Is this normal ?

Re: LinuxMint19 - Wifi often disconnect
Yeap !
I did all the things written by Catweazel and I reboot my computer.
I type the iwconfig command and I can see power management off in the result !
So, for now I will see how it runs !
Thank you !

Re: LinuxMint19 - Wifi often disconnect
See the wireless script link in my signature and post results
Re: LinuxMint19 - Wifi often disconnect
Hi Jeremy !
The script do not work (not able to connect by SSl).
Where can I change the settings on the wifi router to wireless B/G rather than B/G/N? as it is written in the post.
Thank you !

Thank you,
I have solved the problem with this solution that has arriver in another post :
To open the conf.d file as administrator, we need to open a terminal and typeTurn of power saving in Network Manager, you do that by opening the file manager and navigating to /etc/NetworkManager/
once there right click on conf.d and open as administrator change the wifi.powersave = 3 line to wifi.powersave=2 then reboot. If it does not help you can change it back
Code: Select all
sudo nano /etc/NetworkManager/conf.d
