How to enable Ralink RT5572 wifi module

[mathieu]

Hello,

I would like to enable my wifi module
( https://www.amazon.fr/gp/product/B00RFLHF14/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1 , https://wikidevi.com/wiki/Ralink_RT5572 , https://wiki.debian.org/rt2800usb )

It should be working out of the box but doesn't on the olimex board and I can't point out why.

The device is listed in the usb devices but ifconfig dosen't show any wlan (or new) interfaces :

I also made sure all the driver I can think of are installed:

Does anyone know of a possible solution ?

I think the firmware is probably not any Linux driver(s) but rather the data (firmware) needed (if any) to be sent across to the device.

syslog / dmesg may show you more about what the kernel finds and maybe tries to do with the device (and if it fails, why).

Have a look online for what the driver name is and then check you have it.  (And you may need to insmod it.)

edit: oh sorry I see you found the debian info - but is it actually there, built, etc?  (It _should_ be but...)

Hi and thanks for the reply.

The rt2800usb driver needed for the usb dongle is there but not shown in lsmod.

Since insmod doesn't seems to work I tried

Code Select Expand

modprobe rt2800usb

It then shows up

Code Select Expand

root@A20-OLinuXino:~# lsmod | grep rt2*
rt2800usb              13593  0
rt2800lib              48726  1 rt2800usb
rt2x00usb              11120  1 rt2800usb
rt2x00lib              42574  3 rt2x00usb,rt2800lib,rt2800usb
mac80211              247555  3 rt2x00lib,rt2x00usb,rt2800lib


But ifconfig still doesn't show any new interfaces, I don't understand. What I'm doing wrong ?



Even tho I don't know much about compiling and find it a bit scary I also tried to compile this driver : https://www.mediatek.com/products/broadbandWifi/rt5572

But the make command gives the return :

Code Select Expand

make[1]: *** /lib/modules/3.4.103-00033-g9a1cd03-dirty/build: No such file or directory.  Stop.
It seems that the build file does exist but is just a link to "/home/gogo/a20-olimex/linux-sunxi" which dosen't exist, the only file in my home directory is "olimex".
