I am beginner level to Ubuntu, so apologies in advance if this is presented illogically or missing details. I made the error of updating my OS to Ubuntu 22.04. I am running a dual boot windows 10/ubuntu PC with fastboot and secure booth both turned off. Prior to the update from 20.4 this set up was working without issue. My windows install remains unaffected.
During the update, I noticed that the internet went down and on restarting, the PC was unable to make any internet connections of any sort. I am unable to turn on WIFI, bluetooth or connect via a wired USB connection from my android phone. Although other answers suggest a driver problem, this makes me suspect a more central issue. During my searching I had wondered if this may be some incompatibility due to my VPN which I initially disconnected and have since uninstalled, there appear to be no active connections related to it.
Similar to other questions, the wireless icon does not appear in the menu near the power button, and the wifi option setting is only found via search and then returns "no wireless adapter is found". Wired tethering is not recognised as an internet connection, and so workarounds which rely on transmitting an internet connection fail for me. I am unable to turn on my bluetooth although the option is available in the menu, it has no effect.
I can ping local ip

Thanks David. It turns out my wireless adapter was not being claimed, and there was an issue with the driver causing both my wireless and bluetooth issues. I had to reinstall the driver for my Intel Wireless 8265 / 8275 adapter.
In case this helps save someone else a day of pain. To solve this:
On on my Windows PC, I downloaded the following packages (amd64):
- Linux-modules-extra-5.19.0-38-generic:
- Linux-hwe-5.19-headers-5.19.0-38:
- Linux-headers-5.19.0-38-generic:
- linux-headers-5.19.0-38-generic:
- linux-modules-extra-5.19.0-38-generic:
I transferred these packages to the Ubuntu machine using a USB stick.
In the terminal on the Ubuntu machine, I navigated to the directory containing the downloaded .deb files.
And ran:
sudo apt install ./*.deb
this didn't work but
sudo apt --fix broken
did
This installed the missing packages and fixed the dependency issues.
sudo reboot
to check new kernel is in use
uname -r
this fixed both my wireless adapter and bluetooth issues
I then had to fix my DNS settings:
I ran the following command to open the Netplan configuration file using a text editor (nano in this example):
bash
sudo nano /etc/netplan/01-network-manager-all.yaml
If the file doesn't exist, try creating it:
sudo touch /etc/netplan/01-network-manager-all.yaml sudo nano
/etc/netplan/01-network-manager-all.yaml
Add the following lines to the configuration file, replacing any existing content:
yaml Copy code network: version: 2 renderer: NetworkManager
ethernets:
enp3s0:
dhcp4: yes
dhcp4-overrides:
use-dns: false
nameservers:
addresses: [8.8.8.8, 8.8.4.4]
Initially didn't work but reloaded with cloudfare dns (1.1.1.1, 1.0.0.1) did
I saved the changes and exited the text editor.
I applied the new Netplan configuration with the following command:
sudo netplan apply
Restart your network manager:
sudo systemctl restart NetworkManager
Test your internet connection by browsing websites or using ping commands.
