USB WiFi Dongle ID 148f:7601 Mediatek 7601 -not recognised

Fri Mar 28, 2014 1:08 pm

ID 148f:7601 Mediatek 7601 USB WiFi Dongles seem to be offered by ebay sellers and have been for quite some time.

{I have now accumalated 6 which are ideal for Windozy Machines}

Whilst I appreciate that a more knowledgable user can compile a driver, is it feasible to be included in Raspbian Kernel ?

Alternatively is there an easy and straightforward install guide, which does not rely on a deep understanding of Linux innards ?

There are a load of posts about this adaptor on the forum. Whether any of them may help or not I don't know but try searching for 7601 on the forum to get a large list of relevant posts.

Yes I have searched, but most talk about compiling the kernel etal, though I use Linux I still have lots to learn, and some threads meander, the nearest I found is

http://gowthamgowtham.blogspot.co.uk/20 ... er-in.html

..which is the older kernel relevent !

I can not be the only Pi User who has this adaptor and feel lost ??

Basically what would be great is for like earlier Ralink Chipsets it could be added to the Kernel, but for now will just use Realtek 8188CUS !

This

indicates the driver you have is not valid for the version of the kernel you are using.

Check the kernel version you are using with command

Code: Select all

uname -a
particularly 3.xx.yy+ #zzz.Then you need to find a version of the driver for that kernel version which you are running.

Hi Cancelor,

OK, I've attempted to compile the driver for 3.6.11+ #538 and I've put it on Dropbox. I have no idea whether it will work or not as I do not have a wifi module to test it with or an SD card with that version of linux installed to even see if it will load correctly.

Anyway you should be able to download and install it with these commands

Code: Select all

wget https://dl.dropboxusercontent.com/u/80256631/MT7601U-3-6-11-538.tar.gz
tar -xzvf MT7601U-3-6-11-538.tar.gz
sudo install -m 644 -c mtutil7601Usta.ko /lib/modules/3.6.11+/kernel/drivers/net/wireless/
sudo depmod -a 3.6.11+
sudo rm -rf /etc/Wireless/RT2870STA
sudo mkdir /etc/Wireless/RT2870STA
sudo cp RT2870STA.dat /etc/Wireless/RT2870STA/.
sudo install -m 644 -c mt7601Usta.ko /lib/modules/3.6.11+/kernel/drivers/net/wireless/
sudo depmod -a 3.6.11+
sudo install -m 644 -c mtnet7601Usta.ko /lib/modules/3.6.11+/kernel/drivers/net/wireless/
sudo depmod -a 3.6.11+
These instructions for installing are what the make install command from the driver code uses to install the driver.

Hopefully it will work but I have no idea whether it will or not.

Many many thanks for that, it's helped me understand depmod and a few other things.

Unfortunately before I could try it out I did something major wrong and lost the SD card .... now got new install of NOOBS 1.3.5 but can't ssh over cable and pi powered of when I plugged wifi dongle in :((

I'll struggle with it for a few more days and report back.

OK, not to worry.

One thing to note. If you plug a USB device directly into a USB port on the Pi while it's powered on it's very likely to crash and restart, especially with higher current devices like wifi modules. This is standard behaviour. You need to plug it in before applying power to the Pi.

Don't use the ones I compiled. They will only work with 3.6.11+.

Try the ones you already have.

Well, took rather longer than expected. For some reason I haven't figured out yet the modules appeared to be compiling for 3.12.18+. I've no idea why as the linux source was configured for 3.10.25+. Think my brains leaking somewhere :?

Anyway after trying again I finally have a set of modules that load OK with 3.10.25+ #622.

Here's a slightly different set of install instructions to the previous ones. The install instructions are slightly different and should allow any previously installed modules to be overwritten with the new ones.

Code: Select all

wget https://dl.dropboxusercontent.com/u/80256631/MT7601U-3.10.25-622.tar.gz
tar -xzvf MT7601U-3.10.25-622.tar.gz
sudo rm -rf /etc/Wireless/RT2870STA
sudo mkdir /etc/Wireless/RT2870STA
sudo cp RT2870STA.dat /etc/Wireless/RT2870STA/.
sudo install -p -m 644 mtutil7601Usta.ko /lib/modules/3.10.25+/kernel/drivers/net/wireless/
sudo install -p -m 644 mt7601Usta.ko /lib/modules/3.10.25+/kernel/drivers/net/wireless/
sudo install -p -m 644 mtnet7601Usta.ko /lib/modules/3.10.25+/kernel/drivers/net/wireless/
sudo depmod 3.10.25+
These install on my Pi OK but I don't have a wifi module to try with them but hopefully they will work for you OK

Have fun.

Brilliant!! ifconfig shows your wifi has an IP so it must be connected which is really great. Well worth the effort.

It's possible that because the wifi has the name ra0 rather than wlan0 this may cause problems with Wifi-Config recognising it, I don't know for sure, but maybe someone else can help here.

Wifi-Config can also ignore the wifi if the /etc/network/interfaces is altered from the default, so changing the wifi name to ra0 could possibly effect it, or if wpa_supplicant.conf is set in a way it doesn't use, whatever that might be.

Anyway great to hear you're making good progress, so have fun with your Pi.

Hi Cancelor,

Yes, Oh dear. :D

Both 3.12.19+ and #684 are significant. If the version, here 3.12.19+, changes you may or may not need a new driver. And again even if the version remains the same if the build, in this case #684, changes you may again need a new driver.

Anyway, try these commands to grab an updated driver

Code: Select all

wget https://dl.dropboxusercontent.com/u/80256631/MT7601U-3.12.19-684.tar.gz
tar -xzvf MT7601U-3.12.19-684.tar.gz
sudo rm -rf /etc/Wireless/RT2870STA
sudo mkdir -p /etc/Wireless/RT2870STA
sudo cp RT2870STA.dat /etc/Wireless/RT2870STA/.
sudo install -p -m 644 mtutil7601Usta.ko /lib/modules/3.12.19+/kernel/drivers/net/wireless/
sudo install -p -m 644 mt7601Usta.ko /lib/modules/3.12.19+/kernel/drivers/net/wireless/
sudo install -p -m 644 mtnet7601Usta.ko /lib/modules/3.12.19+/kernel/drivers/net/wireless/
sudo depmod 3.12.19+
They load OK on 3.12.19+ #684 but haven't been tested as I don't have a wifi module that uses that driver.

Have fun.

Yup, easy peazy lemon squeezy. :D Many thanks once again.

What is the long term solution to this? Are all drivers so version critical?

Is there a wifi dongle that I can buy that always just works? (You can have my old one then!) :twisted:

Re: USB WiFi Dongle ID 148f:7601 Mediatek 7601 -not recognis

The Edimax EW-7811U uses the RTL8188CUS chip set and is very popular, and the driver is included in the raspbian image so there shouldn't be any problems when updating the kernel.

I have several EW-7811Un modules but I also have several TP-LINK TL-WN725N V2 modules. These use the RTL8188EU chip set and the driver is not included but I use these on several of my Pi's rather than the EW-7811Un. It is quite straight forward compiling new modules for new kernel versions if you have the right set up.

I have a clone of the Raspberry Pi Linux and firmware repositories. I have a script I can run to keep them updated. I can compile a new module version with only a couple of commands and it only requires two commands to install the new version of the module so pretty easy when you know how. And having the clone of the Linux and firmware repos allows me to compile modules for pretty much any kernel version if I need to.

And finally, the kernel was updated to 3.12.20+ #685 a couple of hours ago. I compiled a new module for the TP-LINK TL-WN725N V2 but after updating one of my Pi's to 3.12.20+ I found the wifi still worked using the drive compiled for 3.12.19+ #684 so I didn't need to install the new version of the driver I compiled. So it is not always necessary to recompile the driver when updating the kernel.

I just tried loading the modules from MT7601U-3.12.19-684.tar.gz that I compiled for 3.12.19+ #684 on my Pi running 3.12.20+ #685 and they load OK.

Here's part of the output from the lsmod command that lists loaded modules

Code: Select all

[email protected] ~ $ lsmod
Module                  Size  Used by
mtnet7601Usta          34563  0

If there was a problem with them they wouldn't load so you should be alright if you fancy updating. You will need to re-install them. Just change instructions in the previous post changing 3.12.19+ to 3.12.20+.

If you only have a wifi connection it is possible to update using rpi-update and also install the wifi modules without connecting a network cable.

First run command sudo rpi-update but DO NOT REBOOT when it finishes. Now install the wifi modules changing 3.12.19+ to 3.12.20+ in the instructions as necessary. You should only need to run the three install commands and the depmod command . When you have finished installing the wifi modules you can reboot and you should find your wifi is working.
