Using WiFi USB Adapter with Ralink RT5370 at Raspberry Pi maybe has a different approach like other WiFi adapter. This article is ease your mind when using this type of wifi adaptor.
Using in OpenELEC XBMC.
Setting up the USB is very easy because the module is already there. What give us a headache is sometimes XBMC not detect the network interface.
In order to get the wifi network interface works, make sure wifi USB adapter is connected properly. Then, at the XBMC setting, (refer above screenshot), change network interface between wlan1 to wlan0 or vice-versa that work for it.
Using in Debian Whezzy.
Once the wifi USB adapter attached to Raspi, type command "lsusb". Linux should detect the USB and detect as,
Bus 001 Device 005: ID 148f:5370 Ralink Technology Corp. RT5370 Wireless Adaptor
If there is no result as above, please check your USB.
And also, if you type "lsmod", Linux will produce this result.
rt2800usb 14940 0
rt2800lib 55351 1 rt2800usb
rt2x00usb 11215 1 rt2800usb
rt2x00lib 42335 3 rt2x00usb,rt2800lib,rt2800usb

cfg80211 184163 2 mac80211,rt2x00lib
crc_ccitt 1522 1 rt2800lib
After that, we set the wifi setting by editing wpa_supplicant.conf file.
#sudo nano /etc/wpa_supplicant/wpa_supplicant.conf
And edit the file like above screenshot. Remember, ssid and pask (key) is depend on your wifi network.
If you confident, you can restart the raspi.
If not, you can restart network interface manually and check the network properties.
Type this to stop wifi network interface.
#sudo wpa_action wlan0 stop
Type this to start wifi network interface.
#sudo ifup wlan0
Type this to check wifi network interface and it properties.
#sudo wpa_cli status
Working network will produce result as below.
