The first thing to say is that I have explored and tried the solutions suggested in other similar questions but so far nothing has worked. I know the USB Wifi is not faulty as it just works fine in Windows 10 on the same machine. Incidentally it also doesn't work in Mac OS 10.13.6 (This is a 2011 MacBook Pro with a broken internal WiFi adapter).

lsusb

gives the following: Bus 002 Device 006: ID 148f:7601 Ralink Technology, Corp. MT7601U Wireless Adapter

dmesg

just after plugging the device in gives:

[ 2265.257271] usb 1-1.3: new high-speed USB device number 11 using ehci-pci
[ 2265.376911] usb 1-1.3: New USB device found, idVendor=148f, idProduct=7601
[ 2265.376915] usb 1-1.3: New USB device strings: Mfr=1, Product=2, SerialNumber=3

[ 2265.376919] usb 1-1.3: Manufacturer: MediaTek
[ 2265.376921] usb 1-1.3: SerialNumber: 1.0

If I try iwconfig:

$ iwconfig
lo        no wireless extensions.

enp2s0f0  no wireless extensions.

I have downloaded the firmware from the Mediatek website and put it in the right folder and have also tried to compile or install various packages which either threw compilation errors or did nothing to get the WiFi working.

Does anyone have any advice or an up-to date solution for this?

I tried to follow the instructions given for @chili555's answer:

$ md5sum /lib/firmware/mt7610u.bin
696cedb8e76ecc0cda9f9b0d3972c64d  /lib/firmware/mt7610u.bin

Then:

$ sudo dpkg -s linux-firmware | grep Version
Version: 1.173.2

Having followed advice below and installing latest version of firmware:

$ dmesg | grep ath
$ md5sum /lib/firmware/mt7610u.bin
696cedb8e76ecc0cda9f9b0d3972c64d  /lib/firmware/mt7610u.bin

This is still the same as before.

    Seems like an exact duplicate of Ralink MT7601U (148f:7601) Wi-Fi adapter installation – user535733 Nov 28 '18 at 13:34
  • That was for Ubuntu 14.04 instead of 18.04, this makes a difference. Apparently it just works in 16.04, for example. – Simon Baldwin Nov 28 '18 at 13:36
  • @chili555's answer will work on 18.04, and is a standard, common solution to install unpackaged firmware. If the device used to work in a previous release of Ubuntu but has since stopped, that's called a regression and should be reported as a bug...unless removal was intentional (almost never). – user535733 Nov 28 '18 at 13:41
  • Isn't the driver mt7601u already installed in 18.04? Check: sudo updatedb && locate mt7601u.ko If you find it, load it and look for errors in the log: sudo modprobe mt7601u && dmesg | grep mt76 Is it missing firmware? – chili555 Nov 28 '18 at 15:26
  • There are a couple of firmware versions out there. Let's see which you have: md5sum /lib/firmware/mt7610u.bin On my system, it returns 9a047587617c9c8732b9c546fb4a0152. – chili555 Nov 28 '18 at 16:10

Your firmware file, mt7610u.bin, has a different md5sum and is presumably different that the latest included in linux-firmware. Let's install the later package and see if the mysterious errors disappear.

With a working internet connection by ethernet, tethering or whatever means possible, open a terminal and do:

cd /tmp
wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.175.1_all.deb
sudo dpkg -i linux-firmware*.deb

Reboot and check:

dmesg | grep ath
