Setting up Wi-Fi with the Command lineSIMON MONKThis tutorial works best if your router is broadcasting the SSID. Make sure the "broadcast SSID" set up on your router! This could not work with "private" SSID setupsSetting up WiFi in occidentalis, is also pretty straight forward. You just need to add the name of your wireless network (its SSID) and your password to a configuration file.Step 1.Boot the Raspberry
One advantage of the Raspberry pi is that it has a strong video decoding capability, and it's a good option to use it to play video. It will be used for the next two seasons as a home media hub, and the XMBC software and RASPBMC distributions make this possible.First, XMBC and RASPBMCXMBC (soon to be renamed Kodi) is a leader in open source Media center software,
