Title: [SOLVED] wifi doesn't work
Last edited by Key In 2/27/2016 14:23 Editor

hello everyone
I have some problem with wifi module.
I removed network-manager and configured wifi in /etc/network/interfaces manually.
  1. auto wlan0
  2. iface wlan0 inet static
  3. address 192.168.111.1
  4. netmask 255.255.255.0
  5. network 192.168.111.0
  6. broadcast 192.168.111.255
  7. wpa-ssid name
  8. wpa-psk pass
Copy the code

then
  1. sudo ifup wlan0
Copy the code
and it used to work well.

But after board restarted, interface wlan0 just disappeared....
iwconfig shows only sit, eth0, and lo interfaces.

dmesg without wifi config | grep wlan:
