Ralink 148f:7601 wifi dongle not working with 4.1.6-v7 #810

[jonfitt]

I've read several posts about dongles which show up as Ralink 148f:7601 and tried to follow the advice, but it's not working for me.
I bought a cheapo dongle called Vafru VN-902H which turns out to be the aforementioned Ralink.

I checked that I have the ralink firmware loaded.

I downloaded what I hope is the right driver from the kind MrEngman, by guessing at a file version and it existed!

There appears to be some problem loading the driver.

The file you downloaded was the wrong one. It should have been mt7601-4.1.6-v7-810.tar.gz. Note the extra "-v7" and lower case in the name "mt7601".

However, the latest code, 4.1.xx(-v7)+ now includes an mt7601 driver but needs the firmware loading as it is not yet included in the firmware-ralink package. This is why you see the error you have in dmesg. You can install the firmware using the command

Code: Select all

sudo wget https://github.com/porjo/mt7601/raw/master/src/mcu/bin/MT7601.bin -O /lib/firmware/mt7601u.bin

After loading the firmware reboot to activate the driver. Also note the case of the text in the filenames as Linux treats all text as case sensitive unlike windows so a file name with upper case letters is not the same as the same name using lower case letters.

Thanks. I'll try that when I get home.
I saw one of your other posts and guessed at the filename. When I got a hit I thought "bingo!"
I'll go to that link and get the right one. Do I need to do anything to "uninstall" the driver I loaded already or will it get overwritten when this new driver "claims" the USB ID?

I really appreciate your help for the community building these drivers and firmware packages. I could only claim to be a journeyman Linux user, everything about the Kernel is a big black box to me. When someone suggests building a kernel module I nope right out of there. I'll learn to do it one day, but today is not that day

It seems like a lot of these cheapo dongles are using the Ralink chip. Have you considered keeping a wiki page of the info with latest links?

[jonfitt]

That got it, thanks. I used the correct driver package you specified and that firmware.

Since the driver package has a very Kernel version specific name I'm wondering if/when I'll need to do this again? Is it the case that if you have to build and add in a driver module that you need to redo it when the kernel changes?

Sorry for the delay in getting back to you.

You only needed to load the driver or the firmware, not both. Normally this would stop the wifi working as you will now have two different drivers installed for the mt7601 but it doesn't appear to for the mt7601 driver as I have tried loading both on my Pi and it is working OK as well with both drivers installed.

Now you have loaded the firmware for the built in driver you should not need to load a new version of the driver if you want to update your kernel as the built in driver will automatically be updated whenever you update the kernel.

Thanx @MrEngman It really works...!!!

I was trying to get working my Wifi adaptor on my pi2 since I got it from amazon(25th may).
I also saw one of ur another post with 3.6.11 or something but mine was 4.1.6-v7+ so not worked that way.
but now its working by just updating firmware by the link given by you...!!

Thank you so much once again ...!!!

also can you please help me with setting up my pi as wifi AP with direct login to my ISP pppoe through eth...!!
is there any GUI for it???(as like wpa.gui)

[swap.it]

@MrEngman

It works indeed : viewtopic.php?p=808093#p808093

Many thanks. You saved my WiFi adapter from going into trash...!!!

[megasoft]

Thanks MrEngman. Your excellent post got it to work for me as well!

[mistergiu]

Thank you, but it seems it doesn't work.

Maybe because of the kernel version?

The mt7601u driver is now included in the raspbian image but it may need firmware installing. You can install the firmware using command

Code: Select all

sudo wget https://github.com/porjo/mt7601/raw/master/src/mcu/bin/MT7601.bin -O /lib/firmware/mt7601u.bin

Reboot after installing the firmware and your wifi should start working.

Hi everybody,
