Internet issues after upgrading to 22.10

sv flag

After upgrading to 22.10, my WiFi is not worling properly. I am using a MacBook Pro, with a Broadcom device.. LAN works fine, i can ping other devices on my home network, I can remote control the MacBook from a windows computer and I can ping 8.8.8.8, but can't access the internet and it seems like the network-manager service is missing.. This worked fine in 22.04.

Please help!

Update: Output from terminal:

What do you mean by "WAN"? Is it Wi-FI? Please [edit] your question and add output of `lspci -knn | grep Net -A3` terminal command.

If you can ping 8.8.8.8 then networking itself is probably fine. However, it might be DNS which is failing. Can you check the contents of `/etc/resolv.conf` and share with us?

Probably.. running that command yields "cat: /etc/resolv.conf: No such file or directory "

I fixed it! /etc/resolv.conf was corrupt or something.. I did

sudo rm /etc/resolv.conf

then I created a new resolv.conf

sudo nano /etc/resolv.conf

and added the line

nameserver 8.8.8.8

after that I reconnected to my WiFi and I am back in the game

Thank you for taking the time to hep me out! :)

A wrong driver is installed.

Run

sudo apt purge bcmwl-kernel-source
sudo apt install firmware-b43-installer
sudo modprobe b43

This didn't work.. sudo apt install firmware-b43-installer requires a connection but even wired ethernet doesn't connect to the internet..

Use a phone to get an internet connection.

Doesn't work either... probably something wrong with dns-configuration

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
