The icon in the tray does not show any wireless interfaces when I click on it. I know my adapter SHOULD work (Tenda W522U), but it does not appear to. I am running Raspbian Jessie. The output of commands is listed below.

  • try running the command sudo ifconfig wlan0 up Apr 15, 2016 at 19:35
  • Still nothing. No output in the terminal, either.

  • have you tried to set a static IP? Don't do that yet if you haven't. Apr 15, 2016 at 19:38
  • I have before. It worked on Raspbian Wheezy over Ethernet.

  • Try rebooting and leave the wireless adapter plugged in. Then try ifconfig wlan0 up without an ethernet plugged in Apr 15, 2016 at 19:44

I just struggled with the same problem. I noticed that if I ran ifconfig wlan0 would show up but I would only have an ipv6 adress, the other one was completely gone.

I read that in the release of Raspian Jessie the way you have to configure wifi changed. Instead of setting up my static ip adress in /etc/network/interfaces I put them in /etc/dhcpcd.conf

To configure my static ip I added the following lines at the end of the file. (Of course you have to replace the stuff with what's applicable to your network settings)

interface wlan0
static ip_address=192.168.xx.x/24
static routers=192.168.xx.x
static domain_name_servers= #DNS server of google 

I read it here (my source is dutch though)

    I was having same problem due to a someone who made a change in the /etc/network/interfaces file and then did not back the change back out. The result of the entry caused the same error as the OP as I think my PI 3 was looking for a specific SSID rather than the auto functionality. I was at a loss until I found this question and answer which told me which file to look at. Thank you so much. Oct 30, 2017 at 4:03

It doesn't work because you broke it by fiddling with the settings. See:- How do I set up networking/WiFi/Static IP
