I am trying to install a Ralink wifi adapter in Ubuntu Desktop 14.04.

The system is not detecting the wifi.

  1. lsusb lists the device as:

    Bus 002 Device 004: ID 148f:7601 Ralink Technology, Corp.
    
  2. I have the rt2800 USB driver listed in "/etc/modules";

  3. Following some instructions on the web, I tried this command:

    echo 148F 7601 | sudo tee /sys/bus/usb/drivers/rt2800usb/new_i
    
  4. lsmod | grep rt2800 returns the following:

    rt2800usb              26581  0 
    rt2x00usb              20041  1 rt2800usb
    rt2800lib              83150  1 rt2800usb
    rt2x00lib              48886  3 rt2x00usb,rt2800lib,rt2800usb
    mac80211              545990  3 rt2x00lib,rt2x00usb,rt2800lib
    crc_ccitt              12627  1 rt2800lib

I suggest you get a temporary internet connection, ethernet, tethered or whatever is available. Then do:

sudo apt-get install linux-headers-generic build-essential git
git clone https://github.com/art567/mt7601usta.git
cd mt7601usta/src 
make
sudo make install
sudo mkdir -p /etc/Wireless/RT2870STA/
sudo cp RT2870STA.dat /etc/Wireless/RT2870STA/
sudo modprobe mt7601Usta

Your wireless should now be working.

You have compiled the driver for your current kernel version only. When Update Manager installs a later linux-image, after the required reboot, you must re-compile:

cd mt7601/src
make clean
make
sudo make install
sudo modprobe mt7601Usta

Please retain the files and these instructions for that time. Glad it's working!

From Ubuntu 14.04 up to 15.04

The driver can be installed via a PPA:

sudo apt-add-repository ppa:thopiekar/mt7601
sudo apt-get update
sudo apt-get install mt7601-sta-dkms

Ubuntu 14.04 with kernel 4.2 and Ubuntu 15.10

The mt7601u driver was included in Linux kernel 4.2 but the firmware required by this adapter was not included in the package linux-firmware from Ubuntu 15.10 repository. The firmware can be downloaded from here and must be saved to /lib/firmware/mt7601u.bin ( <- must be lowercase). Run the following to download the firmware to the right location:

sudo wget -O /lib/firmware/mt7601u.bin https://github.com/porjo/mt7601u/tree/master/src/mcu/bin/MT7601.bin

Ubuntu 16.04 onward

The adapter just works.


The following adapters are supported:

  • 0b05:17d3
  • 0e8d:760a
  • 0e8d:760b
  • 13d3:3431
  • 13d3:3434
  • 148f:7601
  • 148f:760a
  • 148f:760b
  • 148f:760c
  • 148f:760d
  • 2001:3d04
  • 2717:4106
  • 2955:0001
  • 2955:1001
  • 2a5f:1000
  • 7392:7710

  • I'm running ubuntu 15.10, and it doesn't work out of the box because the mt7601u.bin firmware file is missing. What package is supposed to provide that file?

  • I'm using ppa:thopiekar/mt7601, but after a kernel upgrade(still using linux kernel 3), when restart the computer, the wifi is lost, so I don't have any internet connection. So, apt-get command just get failed, my question is: are they any way to install this driver offline. For example, I just download the deb file and use the usb stick to copy from another computer(I have to manually download the deb? Or are the deb file are still cached in my computer? Thanks

    OK, problem solved, I see that the driver is correctly installed, but due to the secure boot setting, the driver can't be active, so I have to disable the secure boot feature, see here: UEFI/SecureBoot/DKMS - Ubuntu Wiki, I use the method 1, which just select the "Windows UEFI" type to "Other OS" type in the BIOS.

Download Driver and Patch by using the links.

Do not connect the USB:

sudo apt-get install --reinstall linux-headers-generic build-essential  
tar xjf DPO_MT7601U_LinuxSTA_3.0.0.4_20130913.tar.bz2  
cd DPO_MT7601U_LinuxSTA_3.0.0.4_20130913/  
patch -p0 < ~/(ADD THE PATH)/rt2870-mt7601Usta-kuid_t-kgid_t.patch  
make  
su -c 'mkdir -p /etc/Wireless/RT2870STA/'  
su -c 'cp RT2870STA.dat /etc/Wireless/RT2870STA/RT2870STA.dat'  

Connect the USB

su -c '/sbin/insmod os/linux/mt7601Usta.ko'

If works:

su -c 'make install'

What worked for me

kernel version: 4.13.*

  • restart the PC to ensure that no kernel update is pending
  • Get your current kernel version using uname -r command.
  • Get the folder drivers/net/wireless/mediatek/mt7601u from Linux-kernel source tree (https://github.com/torvalds/linux/).

    Must match with your kernel version. Upto the first two-digits, e.g. 4.13 in my case. You will find the exact matched kernel by checking the tags on Github's branch drop-down menu.

  • Remove the device from pc

  • Now, open the phy.c file from the downloaded folder.
  • find the function mt7601u_init_cal in the file
  • Look up for RXIQ. Comment out the lines

//ret = mt7601u_mcu_calibrate(dev, MCU_CAL_RXIQ, 0); //if (ret) // return ret;

  • Build the module using make -C /lib/modules/$(uname -r)/build M=$(pwd) modules
  • run sudo rmmod mt7601u
  • run sudo insmod mt7601u.ko
  • now, insert the device to pc
  • check kernel messages using dmesg if anything is fatal error
  • Check if the new network interface is recognized using ifconfig command

Note

To make sure any of these works, you have to make sure you have updated binutils gcc make patch libgomp glibc-headers glibc-devel kernel-headers kernel-devel dkms installed. Depending on your distro, some of them can be slightly different.

This just means you are supposed to give the path to the patch file.

Just insert the complete location of the patch file. Assuming the file is located at /tmp/patch/rt2870-mt7601Usta-kuid_t-kgid_t.patch, you would use the following command:

patch -p0 < /tmp/patch/rt2870-mt7601Usta-kuid_t-kgid_t.patch

Note that you have to be in the directory where the file you want to patch is located. I assume it is in /tmp/DPO_MT7601U_LinuxSTA_3.0.0.4_20130913/, the directory you're already in.

  • Now i have a new problem. After start Ubuntu and open Firefox or anything Ubuntu was blocked i reset is required: mouse does not move and keyboard lights are flashing: CAPS and Bloqs. Sep 27, 2014 at 14:44
  • The flashing lights indicate a kernel panic. After boot, hit ctrl+alt+f1 and login. search in /var/log/kern.log for errors. (somewhere at the end). Ask a new question for that and give those error messages.
