I downloaded ubuntu dual boot with windows 10 on my dell xps13, but when I try to connect to wifi using ubuntu it says no network devices available, the wifi works when I use windows. Could I please have help accessing a wifi connection? Below are the commands I was told to add. Thanks

lspci -nnk | grep -i network -A2

  • Do you use direct connection also and does that work ? – George Udosen Dec 26 '16 at 3:27
  • My dell xps 13 does not have an ethernet port sorry – Max Dec 26 '16 at 3:31
  • You can summary the code snippets in your question with the output of lspci -nnk | grep -i network -A2 and rfkill list wifi. Furthermore run lsmod and add the output. Are you sure that you posted the entirely output of rfkill list? If Yes try sudo modprobe dell_wmi and run rfkill list wifi again and let us know if the output changes. – Hölderlin Dec 26 '16 at 4:30
  • Sorry im not to familer with all this, could I please have a step by step? Thanks – Max Dec 26 '16 at 7:44
  • Sure, you know what I mean if I said code snippet? 1 step edit your question and delete every line with gray background color, run lspci -nnk | grep -i network -A2, rfkill list wifi and lsmod in a terminal and add the output to your question. – Hölderlin Dec 26 '16 at 8:37
