Wireless setup for Mediatek USB adapter in Linux Mint Debian Edition.(LMDE)

Rusty UNIX/Linux Howto on Mediatek (ra0) wireless USB adaptor configuration.

Note: Please read the document carefully and donot skip any step,I don't own any responsibility of the result of the how-to

Usb wireless adapter: MT 7601U

Operation system: Linux Mint Debian edition

Things I've done:
1) download driver from http://www.ralinktech.com or like use like, I used the drives provided with the Wayona Mini USB adapter.

When i checked the /var/log/syslog I found I have Meiadtek 7601U chipset.

2) copy  linux folder and unzip to /home/rammi/Downloads/linux 

#)bunzip2 DPA_MT7601U_LinuxSTA_3.0.0.4_20130916.tar.bz2

#)tar xvf DPA_MT7601U_LinuxSTA_3.0.0.4_20130916.tar

#)cd DPA_MT7601U_LinuxSTA_3.0.0.4_20130916

3) vi /home/rammi/Downloads/linux/DPA_MT7601U_LinuxSTA_3.0.0.4_20130916config.mk
Change the following attributes from “no (=n)” to "y"

# Support Wpa_Supplicant
HAS_WPA_SUPPLICANT=n

# Support Native WpaSupplicant for Network Maganger
HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=n

… to value “yes (=y)”:

# Support Wpa_Supplicant
HAS_WPA_SUPPLICANT=y

# Support Native WpaSupplicant for Network Maganger
HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y

Save and come out of vi

4) make

5) ./load

after this step you should be able to see device ra0 with some ipadress and in UP state.

 

#) iwlist ra0 scanning

ra0       Scan completed :
          Cell 01 - Address: D0:7A:B5:4B:D9:D1
                    Protocol:11b/g/n BW20
                    ESSID:"DAPPI-WAN"
                    Mode:Managed
                    Frequency:2.437 GHz (Channel 6)
                    Quality=23/100  Signal level=-81 dBm  Noise level=-88 dBm
                    Encryption key:on
                    Bit Rates:72 Mb/s
                    IE: WPA Version 1
                        Group Cipher : TKIP
                        Pairwise Ciphers (2) : CCMP TKIP
                        Authentication Suites (1) : PSK
                    IE: IEEE 802.11i/WPA2 Version 1
                        Group Cipher : TKIP
                        Pairwise Ciphers (2) : CCMP TKIP
                        Authentication Suites (1) : PSK
                    IE: Unknown: DE0050F204104A000110104400010210497342550372A0001201054000800060050F20400011011000842726F6164636F6D

You should be able to see your AP name in the scan output.

6) cat the load file

rammi@ramya ~/Downloads/linux/DPA_MT7601U_LinuxSTA_3.0.0.4_20130916 $ cat load
dmesg -c
insmod UTIL/os/linux/mtutil7601Usta.ko
insmod MODULE/os/linux/mt7601Usta.ko
insmod NETIF/os/linux/mtnet7601Usta.ko
ifconfig ra0 10.0.0.100

Copy above listed files to /lib/modules/<your kernel version>/kernel/

7) update /etc/module

etc/modules
# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.
# Parameters can be specified after the module name.
mtutil7601Usta
mt7601Usta
mtnet7601Usta

8) depmod to create the kernel dependency

9) make sure your Internet AP has WPA/WPA2 key management option enabled.

10) setup wpa_supplicant 

wpa_passphrase <password> >> /etc/wpa_supplicant/wpa_supplicant.conf 

 

11) wpa_supplicant conf shopuld look like this 

/etc/wpa_supplicant/wpa_supplicant.conf 

 

network={
ssid="DAPPI_WAN"
#psk="mumma21mia"
psk=b812d469c4d5e72baf96362301b55f33c8675a5dd912b1da56b255c388cf45677

}

12) #  wpa_supplicant -i ra0 -c /etc/wpa_supplicant/wpa_supplicant.conf  &

 

13) you should be able to see wireless network connected to your AP in the systray-->Network settings

I had to spend almost 5-7 hours to search and get all details, following this how-to may take 30 minutes.
