I've spent the last two days reading threads trying to get the internet to work on my laptop and nothing seems to work. I can't get an internet connection PERIOD on this thing. The ethernet port doesn't light up when you plug in the cord. Heard it could've been an issue with the BIOS, but couldn't find anything in the BIOS that could be causing that.

The internet was working perfectly fine when it was running Windows 10, both ethernet and Wi-Fi.

Edit: After running "lspci -nnk | grep -e 0280 -e 0200 -A3", I got these results:

1:00.1 "0805" "14e4" "16bc" -r10 -p01 "1025" "0605"

01:00.2 "0880" "14e4" "16be" -r10 "1025" "0605"

01:00.3 "0880" "14e4" "16bf" -r10 "1025" "0605"

02:00.0 "0280" "14e4" "4358" "105b" "e040"

and running "lshw -C network" gave me:

    Let's start by identifying the exact hardware. Please open a terminal Ctrl+Alt+t and run this command: lspci -nnk | grep -e 0280 -e 0200 -A3 Next, edit your question to add the results. Welcome to Ask Ubuntu. – chili555 Aug 29 '18 at 13:52
  • Add the output of lshw -C network – Kulfy Aug 29 '18 at 14:11
