Get wifi working again after upgrading to Ubuntu 24.04. LTS

  • 772

I have a Dell Inc. XPS 13 7390 notebook with Ubuntu from the year 2020 with an Intel Rivet Killer AX1650W Wireless module supported by Linux and the following specs:

On older Ubuntu LTS the wireless worked but since I upgraded to Ubuntu 24.04.1 LTS I can view but cannot connect to the SSID.

Further Info

  • My Network Adapter is detected by Ubuntu 24.04.1 LTS and I can connect to SSID in the BIOS.
  • My router should be OK, because other devices (Android, Windows 11) can connect. I can give further details if necessary.
  • After starting the notebook, I have no internet access through wireless and no internet access trough Ethernet. I need to run $ sudo dhcpcd to connect to the internet via Ethernet.
$ sudo dhcpcd

no interfaces have a carrier

It seems that my network interfaces were changed. Might that cause problems?

There are posts from others with similar issues, but I didn't find any solutions that worked for me.

    I suspect the problem was switching to the consistent network configuration. Fixing this is beyond my skill level.

    I solved it by doing a fresh install (deleting all previous configurations) of Ubuntu 24.04 and it worked.
