WIFI station mode

Step 1: Insert the wireless adapter into LeMaker Guitar.
Step 2: Download MT7601 file file and insmod mt7601Usta.ko.
NOTE: On V1601 or newer released image, this firmware has already included in the system, so you can skip this step.

sudo wget
tar  -zxf MT7601.tgz
cd MT7601
insmod mt7601Usta.ko

Step 3: Use command below to view the following data.

sudo apt-get install usbutils
ID 148f:7601 Ralink Technology Corp.

Step 4: Copy RT2870STA.dat and RT2870STACard.dat to the /etc/Wireless/RT2870STA directory,if not we have to create it manually.

sudo mkdir /etc/Wireless/RT2870STA -p
cp RT2870STA.dat RT2870STACard.dat /etc/Wireless/RT2870STA

Step 5: Use the command below to check the WIFI module which has been loaded on,and it shows the ra0 on my LeMaker Guitar.Different devices may display various.

ifconfig -a

Step 6: Wpa_gui Configuration
Please refer to the site:
Step 7: Connect to the WIFI Station mode by the wap_gui
Please refer to to configure WIFI with wpa_gui

WIFI AP mode

Step 1: Copy RT2870APCard.dat and RT2870AP.dat to /etc /Wireless/RT2870AP directory.

sudo mkdir /etc/Wireless/RT2870AP -p 
cp RT2870APCard.dat RT2870AP.dat /etc/Wireless/RT2870AP

Step 2: MT7601 AP mode are different from the others,because we do not need to configure udhcpd and hostapd.The network card will automatically transmit a wireless signal after loaded,which call RT2860AP with no password.If station mode drivers have been loaded before using AP mode, we must uninstall it at first(they can not exist at the same time).

ifconfig ra0 down
rmmod mt7601Usta

Step 3: Insmod the AP mode driver:

insmod mt7601Uap.ko
ifconfig ra0 up

Again state: These two drivers can not be loaded at the same time, if you want to switch operating modes,please unload the other driver at first.
