I'm running lubuntu 18.04 64-bit on a Trekstor Surfbook a13b. It is dual-booted with Windows 10, where, hardware-wise, everything works perfectly.
The Problem: Lubuntu can't find any wi-fi adaptors, at all – at least with what I've tried. The same problem persists with various other live-distributions (lubuntu 16.04, ubuntu 18.04, ubuntu mate 18.04 – i can imagine that there's not going to be big differences between those, but still)
Windows says the wi-fi unit is an "Intel Dual Band Wireless-AC 3165", which is supposed to work out of the box in linux (or is at least not supposed to be a huge pain to get to work).
I've tried disabling Secure Boot, and this (including getting newer firmware from here).
To have internet access for troubleshooting, I also plugged in a "devolo wifi stick ac", which works like a charm in Windows, but, same as the internal Intel device, doesn't show up at all in lubuntu 18.04.
As of now, I don't have any means at all to connect to the internet under lubuntu.
Could it be a "general PCI/USB bus error", as mentioned here (top answer, under "Identifying the exact hardware")?
Thanks in advance for any help at all!
