Raspberry Pi Project
Installing A Ralink USB WiFi DongleRaspberry Pi does not have a standard pci slot to install a wifi card but it will power most usb ones. I purchased a Ralink usb wifi dongle and this is how I got it up and running. You can purchase these in a lot of places but I got mine at http://www.dx.com/p/k11-mini-ieee-802-11-b-g-n-150mbps-wi-fi-usb-2-0-dongle-black-147188
To make sure you have the same one as mine go to a termainal and type
You should get a list returned, one item in the list should show
Bus 001 Device 005: ID 148f:7601 Ralink Technology, Corp.
You may have a different bus or device id number but the identification "148f:7601" should be the same
Although it may not be necessary you should keep your PI up to date and should update it now before installing:
Extract and install the driver
Now install the necessary wifi software
If you dont know the name of the ESSID / wifi network name, look it up...
Now we create our configuration files
If you are running the pi via DHCP add the following to the bottom of the file
If you want the pi to have the same address use the following...replacing the address and other network information as needed
Now we need to let the pi know the network name and security password.
At the end of the file place the following. Replace the ESSID_NAME and WIFI_PASSWORD with your own
And now restart the network interfaces
You should now have a connection to your wifi router / access point
