Wifi not working after update - need kernel update

General Help
21

I found out I need to install the deprecated package net-tools in order to use the command ifconfig.
Running the command now results in a description and a list with 0 dropped packages. Are you interested in anything specific, or shall I copy the whole text from the laptop?

Details? Bring it on...

For ifconfig to work you have to install net-tools:

sudo apt-get install net-tools

24

This is odd because I just ran ifconfig without any trouble and without needing to install anything.
How could Ifconfig be missing?

@Aravisian I only know this because I had similar issues - can’t remember but think it might have been regarding the notebook as all desktops are on powerline adapters.

I'm back. Had to wait 13h after using up all the post I can do on the first day...
This is the result of ifconfig

wlp2s0: flags=4098<BROADCAST,MULTICAST> mtu 1500
ether 4c:eb:bd:ba:85:01 txqueuelen 1000 (Ethernet)

Hmm...

Can you enter into terminal:

sudo nano /etc/network/interfaces

You should see

auto lo
iface lo inet loopback

Can you change that to:

auto lo
iface lo inet loopback
auto wlp2s0
iface wlp2s0 inet dhcp

Run in terminal

sudo systemctl enable networking

Reboot and check...

I had to wait another 8h after the last post. But that is fixed now

Somewhere in the wilds of the internet, I read yesterday that linux kernel 5.5 solves the problem. So I did a manual update to linux 5.5.0-generic following these instructions and now the wifi works again.

Thanks to everyone for the help.

And another :heart: from me - once a post is marked as solution you can’t increase the LUV!
