I'm using Raspberry Pi 2 installed with Raspbian (Debian Wheezy) ~ Release date: 2015-02-16.
Every now and then wpa_supplicant
dies on me and usually when I'm remote and I cannot do anything other then physically either reboot the Pi or start the wpa_supplicant
process through the Terminal.
root@raspberrypi:~# ps ax | grep '/sbin/wpa_supplicant' | grep -v grep
1814 ? Ss 0:29 /sbin/wpa_supplicant -s -B -P /var/run/wpa_supplicant.wlan0.pid -i wlan0 -W -D nl80211,wext -c /etc/wpa_supplicant/wpa_supplicant.conf
root@raspberrypi:~#
Is there a service that can be (re)started in order to get it going?
