I had recently installed Ububntu 16.04 on Thinkpad 11e 5th gen but it does not work with the built in network card. However, usb D-link works. But when I upgraded the system it wouldn't work with the external card either. I wonder whether 18.04 works better?

  • 1. Try when booted live from a USB pendrive, 'Try Ubuntu'; 2. Are you talking about wired or wireless network? 3. Please specify brand name and model of the network cards. – sudodus Jun 26 '18 at 18:31
  • Thank you. 1. I used live cd. If this works too I'll try your advise in august -- I travel currently. 2. I was talking about wireless. Didn't have a chance to try wired. 3. USB card is D-Link DWA - 125, what the PCI is I don't know. – anatoly Jun 26 '18 at 19:56
  • It should work to boot from a live DVD too. I am no expert on wifi, but let us hope that wifi experts will see your question, and the more you can tell about the hardware, the better they can help. And I think it will help if you put 'wifi problem' into the title of your question. Good luck :-) – sudodus Jun 26 '18 at 20:08
  • Thanks. Will add "wifi" wherever I can ;) – anatoly Jun 27 '18 at 9:40

    Please edit your question and add output of lspci -knn | grep Net -A3; rfkill list terminal command. – Pilot6 Jun 27 '18 at 11:27
