Wifi not working in Debian 10
by gardenair from LinuxQuestions.org on (#5C7F3)
hi,
I just use Ubuntu 20 live USB in my laptop,wifi works perfect on it. Then I have install Debian 10 on same Laptop.The LAN point is working but i am interested to use wifi.
Following is the output of the list of network interface.
Code:oot@debian:~# lspci | egrep -i --color 'network|ethernet'
00:19.0 Ethernet controller: Intel Corporation 82579LM Gigabit Network Connection (rev 04)
02:00.0 Network controller: Intel Corporation Centrino Advanced-N 6205 [Taylor Peak] (rev 34)
root@debian:~# lspci | egrep -i --color 'network|ethernet|wireless|wi-fi'

I just google it and it shows to add "non-free" component to your /etc/apt/sources.list.
Example
Code:deb http://deb.debian.org/debian buster main contrib non-free
deb-src http://deb.debian.org/debian buster main contrib non-free
deb http://deb.debian.org/debian-security/ buster/updates main contrib non-free

deb http://deb.debian.org/debian buster-updates main contrib non-free
deb-src http://deb.debian.org/debian buster-updates main contrib non-freeFollowing is my own sources.list file.
Code:deb http://deb.debian.org/debian buster main

# deb-src [arch=amd64] http://download.virtualbox.org/virtualbox/debian buster contrib
# deb-src http://deb.debian.org/debian/ buster-updates main contrib
I even add non-free after the bold lines shown above but still no success.
The issue is which firmware may I install for my wifi ? As the output shows that both LAN and WIFI are of Intel Corporation
Thanks.
