If need be, first establish temporary internet connection by other means.

Please generate an overview of your system like this:
- Launch a terminal window (this is how to launch a terminal window);
- Make the terminal window full screen, to avoid chopped lines;
- Copy/paste this command into the terminal:

Code: Select all

inxi -Fxpmrz
(if you type: the letter F is a capital letter, and don't omit the space after inxi!)

Press Enter.

Copy/paste the output in your next message.

Do the same with the following four commands:

Code: Select all

rfkill list all

Code: Select all

iwconfig

Code: Select all

lsusb

Code: Select all

lspci

OK, Intel wireless running on the iwlwifi driver....

First try a newer kernel series:
Update Manager - panel: View - Linux kernels
Install the latest kernel of the 5.8 series. Then reboot.

When no avail, try some of the things mentioned on this page:

I have installed Mint, everything work fine
The only little issue was a WiFi drop sometimes.
Sometimes I mean a couple of drop in a week. Mint re ask me for a password and everything come back to work fine.

After my First post in this Page i performed this command line

Code: Select all

sudo sed -i 's/3/2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

Like I said , after this comand my wifi line got worse
It drop every few minutes. And the connection was absolutely not stable.

Every One known how can I resolve?

Try, reload wifi driver:

Code: Select all

 sudo modprobe -r iwlwifi && sudo modprobe iwlwifi 

Or, restart Network Manager:

Code: Select all

 sudo service network-manager restart
