Today I tried installing Linux for the first time, and I can't get the Wi-Fi working. The Wi-Fi is built into the laptop, not a dongle.

  • Firstly, how do I know that Ubuntu is even seeing the card? ip link sho | grep w gives me a result. Will the result be the Wi-Fi card and not something else like the USB Ethernet dongle?
    • Based on the output, the card is down. Nothing seems to enable it. e.g. sudo ifconfig <name> up makes no difference
    • sudo rfkil shows this interface is unblocked, both soft and hard
    • trying the command:wpa_passphrase MYSSID passphrase > /etc/wpa_supplicant.conf results in permission denied, even if I try using sudo

Can someone please suggest what I should try next - or possibly try in the correct sequence.

Edited to add more information: This is the walkthrough that I found yesterday before coming here for help:

Martin Thornton gave me the correct syntax to get the wpa_passphrase working. When I run iwlist scan, which is the next step in the walkthrough, it tells me the network is down.

The documentation linked below starts off with "Open the system menu" I don't think I have a menu?

Running lspci tells me the wireless card is an:

Intel Wireless 7260 (8086:08b1) rev 6b

sudo lshw -C network told me the wireless interface was disabled after running sudo ip link set wlp6s0 up, it seems the card is up. But iwlist scan still returns no scan results

  • I'd suggest installing a desktop version instead of a server one. – fkraiem Jun 29 '19 at 11:13
  • Regarding the "permission denied", because of the output redirection you'll need to use sudo this way: wpa_passphrase MYSSID passphrase | sudo tee /etc/wpa_supplicant.conf. – Martin Thornton Jun 29 '19 at 11:37

    wifi isn't usually found on servers, but did you get far with the documentation (https://help.ubuntu.com/stable/ubuntu-help/net-wireless-connect.html.en or https://help.ubuntu.com/stable/ubuntu-help/net-wireless-troubleshooting-hardware-check.html.en) If so providing us with details of your wireless card would be useful via sudo lshw -C network (list-hardware of class=network found on the troubleshooer help page) – guiverc Jun 29 '19 at 11:46
  • @fkraiem our linux guy in the office quit, and I need to work on our servers. – kamuzz Jun 29 '19 at 11:49
