I just received my new computer which was delivered with Ubuntu as operating system. The computer is a Dell laptop Dell G5 15 - 5587.
At this point the wifi was working well as I used it to download the debian netinstall image.
After installing Debian Stretch on my computer (using ethernet for convinience) I have no wifi interface available.
At this point I checked that the hardware was discovered.

# lspci | grep -i network

So right now I don't think that Ubuntu was distributed a kernel version greater than 4.18.x (I didn't checked), so I think that I may be a configuration issue.
The next try could be to rebuild the kernel from sources trying to find an option matching my wireless controller but I would like to have some opinions before rebuilding the kernel.
Do you think that the problem could come from kernel options ? ==> Could rebuilding the kernel solve the issue ?
Am I missing something with configuration ?
