(Using ubuntu 14 on a laptop) I followed this guide to set up my wifi by sshing into the pi via ethernet. I checked my routers networks settings and it showed two ip addresses from the pi, and I could ssh into the wireless address without a problem.
When I unlplugged the ethernet and restarted the pi the wifi address does not show up, and I can't ssh in.
I tried restarting it with and without ethernet with the same results. whats happening?
Here is my interfaces file:
auto lo
iface lo inet loopback
iface eth0 inet dhcp
allow-hotplug wlan0
auto wlan0
iface wlan0 inet dhcp
wpa-ssid "Patty likes oldman"
wpa-psk "analrapist"
wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
iface default inet dhcp
Here is my wpa_supplicant.conf file:
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
network={
ssid="Patty like oldman"
psk="analrapist"
