I have Ubuntu 18.04 on an MSI GS 65. The wireless doesn't work: it says no wifi adapter found. lshw -C network says a network is UNCLAIMED.

hello:~$ sudo lshw -C network
  *-network UNCLAIMED

The problem is similar to this SO question but I have a different kernel version: 4.15.0-43-generic.

Contrary to this post I think the wireless used to work but has stopped working since I installed some Ubuntu suggested updates. But I am not too sure.

I checked my device using lspci -knn | grep Net -A3. This gave me the PCI id (8086:a370). I searched with that and found this forum. It clearly says that it is supported for kernel >= 4.16. Ubuntu 18.04 has 4.15.

You can just upgrade the kernel to solve the problem. Since I have nvidia drivers installed I upgraded to Ubuntu 18.10 which has 4.18. This indeed solved the problem.
