Since kernel updated from 4.13.0-41 to 4.15.0-29, wifi does not work

[Jason Bassett]

Hello

All was working fine until I updated Ubuntu using apt-get and it installed Kernel version:

4.15.0-29-generic

Now wifi does not work but Ethernet cable connection is still fine.

If I reboot into the old kernel by selecting it in advanced boot options, all is fine.

Working Kernel version is:

4.13.0-41-generic

I am using a Dell Vostro 1540 laptop.

Description: Ubuntu 16.04.5 LTS
Release: 16.04

All other laptops I use have updated and are fine, including a Dell Inspiron.

Regards

Jason
