Issue with MT7601U usb dongle wifi driver

Question

I bought a usb wifi dongle for my Raspberry Pi B+ and I can't install it on my RPi with 3.18.3+ kernel (OS: raspbian).

Here are the steps that I follow with no success:

lsusb give me this output:

Bus 001 Device 004: ID 148f:7601 Ralink Technology, Corp. MT7601U Wireless Adapter

I downloaded the lastest kernel release on github and extracted it: https://github.com/raspberrypi/linux/rpi-3.18.y.tar.gz

made these instructions into rpi-linux-3.18 folder with no errors

make mrproper
zcat /proc/config.gz > .config
cp .config .config.org
sed -i 's/^CONFIG_CROSS_COMPILE.*/CONFIG_CROSS_COMPILE=""/' .config
make modules_prepare
wget https://raw.github.com/raspberrypi/firmware/master/extra/Module.symvers

then I got the MTU7601U driver from MediaTek (file: DPO_MT7601U_LinuxSTA_3.0.0.4_20130913.tar.bz2 )

extracted it then proceed to make && make install. In my first attempts I couldn't run correctly make because of an error with a struct in the rt_linux.h.

error: incompatible types when assigning to type ‘int’ from type ‘kuid_t’
error: incompatible types when assigning to type ‘int’ from type ‘kgid_t’

so I made a patch in this file by replacing int by kuid_t and kgid_t respectively (maybe the driver doesn't work cause of it ?)

Then I make && make install once again and (with lot of warnings) the driver compiled.

I installed by run:

sudo insmod /lib/modules/3.18.3/kernel/drivers/net//wireless/mt7601Usta.ko

And reboot my rpi.. But when i plug my usb wifi dongle I get this error:

I tried to recompile again and again but this issue came.

Does anyone know how to compile this driver for my version or know what have I done wrong?

@Ghanima Thank you and thank you for the edit, and sorry for the mistakes! — Matthieu Durindel, Jan 29, 2015 at 9:39
You might try this version of the driver instead: github.com/porjo/mt7601 If it works, please add this as an answer to your own question. — goldilocks, Jan 29, 2015 at 10:36
I have the same issue with this driver. I followed the readme on github but when I run this command insmod os/linux/mt7601Usta.ko I get [ 2443.969818] Internal error: Oops: 5 [#1] PREEMPT ARM — Matthieu Durindel, Jan 29, 2015 at 11:33
Poorly explained. Change "int" to "kuid_t" and "kgid_t", the file has 1600 lines. Where you make this change? — user31871, Jun 15, 2015 at 11:16

Please try the following way.

(1)Update package
$ sudo apt-get update
$ sudo apt-get upgrade

(2)Update Firmware to 3.18.6
$ sudo rpi-update 3f11b3fb1f390b60daa22f2ca2ecda5266295a84
$ sudo reboot

(3)Install driver
$ wget https://dl.dropboxusercontent.com/u/67643651/mt7601_3.18.6_753.tar.gz
$ sudo tar xf mt7601_3.18.6_753.tar.gz -C /
$ sudo depmod 3.18.6+
$ sudo reboot

(4)Edit /etc/network/interfaces
$ sudo vi /etc/network/interfaces
auto lo

iface lo inet loopback
iface eth0 inet dhcp

#allow-hotplug wlan0　→comment out
#iface wlan0 inet manual　→comment out
#wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf　→comment out
#iface default inet dhcp　→comment out

#insert 4 line
auto ra0
allow-hotplug ra0
iface ra0 inet dhcp
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

(5)Edit /etc/wpa_supplicant/wpa_supplicant.conf
$ sudo sh -c "wpa_passphrase XXXXX YYYYY >> /etc/wpa_supplicant/wpa_supplicant.conf"

XXXXX=Access Point SSID
YYYY=Access Point Password

$ sudo vi /etc/wpa_supplicant/wpa_supplicant.conf
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
        ssid="YOURWIFINAME"
        key_mgmt=WPA-PSK　→Insert
        psk="YOURPASSWORD"
}

(7)Reboot

Thank you very much, it works great. Can you give the steps to compile these drivers, please ?

on OSMC, which should be a regular jesee, it can't find rpi-firmware command...

I had to replace ra0 with wlan0 for this to work for me.

Trust me - it simply isn't worth spending time trying to get this particular WiFi dongle working. It takes way too many steps and all that effort goes down the drain everytime the kernel or anything else gets updated.

I think your best option is to return/sell/throw the Ralink 7601 and get an RTL8188CUS-based dongle.

I agree, I did it myself and now I found that if I need to do a fresh install, I would have to go through all that pain again, so I'm avoiding that but it would be inevitable at some point :/

Yes the steps to follow are very long, but if the rpi doesn't need to be updated very often it's a good compromise. Thank you for the link

There is a new driver for mt7601u on GitHub, it have been reported to work pretty well with rPI:

https://github.com/kuba-moo/mt7601u

Note that you will need to upgrade your kernel to 3.19 to use it.

I managed to get the MT7601u working on my Raspberry Pi 2 board, using Porjo's driver and adapting some instructions found on the web in order to compile it against the correct kernel. I have posted a write-up here for anyone interested.

I have only tested it on Raspi 2 boards, but I believe it should work on RasPi version 1 as well.
