INSTALL Ralink (CDR-King wifi dongle)

How to install Ralink (cdr-King wifi dongle)

WU-NETA-039-ZI (MT7601Usta)

Raspberry pi B+

I bought a cheap USB Wi-Fi dongle from Cdr-king worth 250php(6$) and I want to connect it to my pi. I’d manage to dig, research to websites, and go to forums. I’ve compiled all my researches then ATLAST I’ve made it WORK!... sorry for my bad English but I hope these steps helps you configuring your dongle.. Goodluck!

First plug-in wifi dongle then power up your pi

Try these commands:

ifconfig

If there is no ra0 displayed in your command line therefore the Pi didn’t recognized your dongle, but don’t worry that will be the thing that we’ll be figuring out.

 lsusb

this command shows the list of USB devices connected to your pi, Ralink Technology, corp is the device ID CDR-king wifi dongle.

Shows:

 lsmod

 don’t worry if you can’t see that mt7601Usta when you lsmod your pi we will be figuring out that too. :D

Shows:

After you tried those commands you need to update your pi to ensure you have the latest plugins and apps. This should take time.

Run these commands:

Sudo apt-get update

Sudo apt-get upgrade

Sudo apt-get dist-upgrade

Sudo Rpi-update

Next thing you need to do is to update the kernel version to 3.18.7+ of your pi to make it compatible with your dongle because if you don’t you won’t be seeing that ra01 on ifconfig.

            I’ve been through a lot of research and surfing and found out this Kernel version 3.18.7+ has modules for this kind of dongle.

Follow these commands:

Call directory

cd /tmp

download the kernel version
sudo wget https://dl.dropboxusercontent.com/u/67643651/mt7601_3.18.7_755.tar.gz

extract the files
sudo tar xvzf mt7601_3.18.7_755.tar.gz -C /
sudo depmod 3.18.7+

reboot your pi
sudo reboot

create and setup a new wpa configuration file in etc

sudo nano /etc/wpa.config

input the following:

network={

ssid="WIFI name here"

proto=RSN

key_mgmt=WPA-PSK

pairwise=CCMP TKIP

group=CCMP TKIP

psk="password here"

}

Control+x and save changes.

Next edit network interfaces:

Sudo nano /etc/network/interfaces

Add the following:

auto ra0

iface ra0 inet dhcp

wpa-conf /etc/wpa.config

iface default inet dhcp

control+x and save changes then reboot your pi.

After rebooting the dongle will automatically connect to your network then try ifconfig, if you see the ra0 on ifconfig as well as the IP address of the dongle, then you’re good to go. Install Advance IP scanner on your pc/laptop or any ip scanner app on google play to know the devices connected on your network.

you should see your pi like this. DONE!... now you can ssh your pi wirelessly.You can now go anywhere and Program your Pi via android phone using SSH apps on google play. ENJOY!.
