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!

There are four Hardware-IDs found through the Windows 10 Device Manager:

PCI\VEN_8086&DEV_3165&SUBSYS_80108086&REV_81

  • Is there a setting in the BIOS to enable/disable wifi? We see nothing resembling wireless so far. – chili555 Sep 17 '18 at 21:49
  • I can't find any, and I'd be surprised if it was turned off in the BIOS, since there are no problems with wifi whatsoever when using Windows 10 on the same machine. – mortuant Sep 17 '18 at 21:58
  • Can you go into Windows device manager go into properties for wifi, detail tab, and get the hardware ID and post it – Jeremy31 Sep 18 '18 at 17:06
  • Updated to show the Hardware IDs. – mortuant Sep 18 '18 at 17:34
  • Have you checked the manufacturers web site to see if a BIOS update is available? – Jeremy31 Sep 18 '18 at 20:45
  • There seems to be a driver package available, but I'm not sure for what purpose. I don't see anything labelled "BIOS" in there. http://www.trekstor.de/products/notebook/detail-notebook/product/SURFBOOK%20A13B-PO.html – mortuant Sep 20 '18 at 17:56
