Previous instructions for Wireless / WiFi
I then used this recipe to set up wifi: http://www.dafinga.net/2013/01/how-to-setup-raspberry-pi-with-hidden.html
- wpasupplicant was already installed.
- Somehow the wifi connection didn't work first time round, and while I was playing with lsusb, lsmod, iwconfig it somehow started working. We'll need to see.
- /etc/resolv.conf needed adding another name server - I don't fully understand this, maybe it's a problem with my home network.
The wifi doesn't seem to work that reliably.

The above recipe didn't quite work for me, see forum post on wifi. So I looked back at /etc/network/interfaces and removed wpa-proto, wpa-pairwise, wpa-group configuration. The /etc/network/interfaces now looks like:
auto lo iface lo inet loopback iface eth0 inet dhcp auto wlan0 allow-hotplug wlan0 iface wlan0 inet dhcp wpa-scan-ssid 1 wpa-ap-scan 1 wpa-key-mgmt WPA-PSK wpa-ssid "_MY_SSID_" wpa-psk _MY_PSK_ iface default inet dhcp
In particular these lines messed it up:
wpa-proto RSN WPA wpa-pairwise CCMP TKIP wpa-group CCMP TKIP
The dongle still turns itself off. If you search for something like "edimax 7811un raspberry pi power mode", you'll find options for the power management, edit
and add the line
options 8192cu rtw_power_mgnt=0 rtw_enusbss=0
to turn off power saving. There's also the recommendation to ping the router once per minute, but I'll see whether that's necessary!
