Hi All
I recently setup a RetroPie running on img 2.3. I spend about a week alone trying to setup the wifi, it was not easy! I purchased the RALink Wifi Dongle of eBay however this is not one that runs on RetroPie out of the box and did require a lot of tweaking to get it to work. I searched many sites and resources but after a LOT of trial and error I managed to get it working. I figured I would share how I got it to work so no one else needs to go through what I went through.
First run the following commands:
sudo apt-get install wpasupplicant
sudo apt-get install firmware-ralink
The run:
lsusb
You should see the device listed like below:
Bus 001 Device 007: ID 148f:7601 Ralink Technology, Corp.
Then run the following set of commands, allowing each one to complete before moving onto the next one:
wget https://dl.dropboxusercontent.com/u/67643651/mt7601_3.12.35_730.tar.gz
sudo tar xf mt7601_3.12.35_730.tar.gz -C /
sudo depmod 3.12.35+
cat /lib/modules/3.12.35+/modules.dep | grep mt7601Usta
sudo reboot
Check if everything is OK:
sudo lsmod | grep mt7601Usta
You should see something like below:
mt7601Usta 601487 1
Then run:
iwconfig

Then use the Wi-Fi rename of ra0 on wlan0 and that the file:
sudo nano /etc/udev/rules.d/70-persistent-net.rules
Create and add to:
ACTION=="add", SUBSYSTEM=="net", ATTR{type}=="1", KERNEL=="ra*", NAME = "wlan0"
After a sudo reboot it is successfully renamed wlan0:

Then the file /etc/network/interfaces upgraded with the following information to access with a fixed IP address can:
sudo nano /etc/network/interfaces
auto lo
iface lo inet loopback
iface eth0 inet dhcp
auto wlan0
allow-hotplug wlan0
iface wlan0 inet static
address 7.7.7.50
netmask 255.255.255.0
gateway 7.7.7.1
wpa-ap-scan 1
wpa-scan-ssid 1
wpa-ssid "YOUR-WIFI-NAME"
wpa-psk "YOUR-WIFI-PASSWORD"
After a sudo reboot you can connect to the Raspberry Pi without wires.
I hope that helps :)
