Ralink RT5572 based WiFi Usb Dongle setup on Ubuntu 12.04

September 2, 2012 · ctheroux Ubuntu 11.10 Ubuntu 11.04 Ubuntu Linux WiFI Ubuntu 12.04 RT5572 Ralink

The WiFi USB dongles based on the newest RT5572 chip set do not work out of the box on Ubuntu. Unex DNUR-V72, D-Link DWA-160 Rev B and TP-Link TL-WDN3200 dongles are based on this chipset. You will need to compile the source code of the driver to make it work. Do not leave this page! This involves only a few easy steps.

Save this page's link. You will have to reboot and come back to it.
Un-plug the WiFi USB dongle from your computer.
Reboot your computer.
Download the driver's source code from the manufacturer website. Alternatively, you can download a version of this file from this site. Files have been already edited. Steps 9, 10 and 11 are then unnecessary. Note that the filename is slightly different (DPO_RT5572_LinuxSTA_2.6.0.1_20120629_EDITED.tar.bz2).
Open a terminal window.
Change to the directory that contains the driver's source code downloaded previously. For example,

cd /home/myuser/Downloads

Extract the source code. You might need the modify the file name since Mediatek may publish newer source code. For example (there is two bz2 extensions!),

tar xvf DPO_RT5572_LinuxSTA_2.6.0.1_20120629.tar.bz2

Change to the source code directory

cd DPO_RT5572_LinuxSTA_2.6.0.1_20120629

Edit the file os/linux/config.mk. Set to y the two variables HAS_WPA_SUPPLICANT and HAS_NATIVE_WPA_SUPPLICANT_SUPPORT. Your file shall shows

# Support Wpa_Supplicant
# i.e. wpa_supplicant -Dralink
HAS_WPA_SUPPLICANT=y
# Support Native WpaSupplicant for Network Manager
# i.e. wpa_supplicant -Dwext
HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y

Edit the file os/linux/usb_main_dev.c. Add a line containing MODULE_LICENSE("GPL");. This line is important. The position of the line is important. Your file shall shows

MODULE_DESCRIPTION("RT2870 Wireless Lan Linux Driver");
MODULE_LICENSE("GPL");
#ifdef CONFIG_STA_SUPPORT
#ifdef MODULE_VERSION

Edit the file common/cmm_mac_usb.c and add the lines "#define usb_buffer_alloc(a, b, c, d) usb_alloc_coherent(a, b, c, d)" and "#define usb_buffer_free(a, b, c, d) usb_free_coherent(a, b, c, d)". The position of the lines is important. Your file shall shows

#ifdef RTMP_MAC_USB

#define usb_buffer_alloc(a, b, c, d) usb_alloc_coherent(a, b, c, d)
#define usb_buffer_free(a, b, c, d) usb_free_coherent(a, b, c, d)

#include        "rt_config.h"

In the same directory as step #8, compile the driver's source code. Type the following command:

sudo make

Install the driver. Type the following command:

sudo make install

Plug your WiFi USB dongle.
After a few seconds, you should see an interface called ra0 if you type the following command:

sudo ifconfig

Configure your connection as you would normally do.

wow its works, but i use another DPO files.
how to create usb wifi auto enabled(detected) when computer reboot. thanks

Claude Theroux September 25, 2014

Which one did you use?

anatolii August 29, 2014

cd Desktop/backports-3.11-rc3-1/
make defconfig-wifi
make
sudo make install
sudo modprobe -r rt5572sta
sudo modprobe rt2800usb

@ctheroux,

Although the driver works out the box with Ubuntu 14.04 the free drivers perform horribly compared to the Mediatek drivers. I tried installing it on Ubuntu 14.04 but I get syntax errors and such probably due to new kernel because it works perfectly fine under Debian Wheezy. Any suggestions? I don't know if Ubuntu has any firmware to support in the repos I have checked but no luck.

Thanks!

Georg Mill May 1, 2014

For Ubuntu 14.04 edit DPO_RT5572_LinuxSTA_2.6.1.3_20121022/os/linux/rt_linux.c

Search for these lines:
#if LINUX_VERSION_CODE fsuid = current->fsuid;
pOSFSInfo->fsgid = current->fsgid;
current->fsuid = current->fsgid = 0;

and add directly after these lines the following code:

#else if LINUX_VERSION_CODE >= KERNEL_VERSION(3,13,0)

#endif
This is a really dirty hack, but it works for me.

Erasmus May 24, 2014

Cannot find these lines quoted in the file. What do I add where for ubuntu 14.04?
Thanks so much.

ctheroux May 24, 2014

It works now out of the box with 14.04. There is no need to do this with Ubuntu 14.04.

Aman June 5, 2014

No TL-WN727N wireless adapter does not work out of box with Ubuntu 14.04. I tried all methods over here but nothing is working. Please help.

Georg Mill May 1, 2014

For Ubuntu 14.04 edit DPO_RT5572_LinuxSTA_2.6.1.3_20121022/os/linux/rt_linux.c
and insert

#if LINUX_VERSION_CODE fsuid = current->fsuid;
pOSFSInfo->fsgid = current->fsgid;
current->fsuid = current->fsgid = 0;
#else if LINUX_VERSION_CODE >= KERNEL_VERSION(3,13,0)

#endif
pOSFSInfo->fs = get_fs();
set_fs(KERNEL_DS);
this is a real dirty hack, but it works.

Aman June 5, 2014

this definitely not working . Syntax error in if statement.

Chopo Rito June 30, 2014

I used

pOSFSInfo->fsuid = __kuid_val(current_fsuid());
pOSFSInfo->fsgid = __kgid_val(current_fsgid());

instead of

pOSFSInfo->fsuid = current_fsuid();
pOSFSInfo->fsgid = current_fsgid();

and it worked for me. I think this may be a solution.

hung March 11, 2014

I use your method It works in Ubuntu 12.04 TP link 3200
But when i get software updated from ubuntu i must do to the directory of the the driver run " make " and then " make install" to meke the adapter works again

dlanced February 20, 2014

Hi,
This terrifice page has helped me in the past, but now I'm having trouble using a TP-Link WDN3200 usb adapter (rt5572) on Debian 7.3. When I get to your step 12 (make), I get this output:

Do you have any ideas?
Thanks so much!

Hi, nice guide. Can you please tell me how to uninstall it?

ctheroux February 20, 2014

Did you tried?

Thank u !! I've TP-LINK WDN3200 usb adaptor...can you tell me these steps and driver will be work in Backtrack 5r3??

Toshy January 29, 2014

Really great, no bugs, just followed the instructions and it worked immediately!! Thank you

mrjayviper September 16, 2013

I was finally able to compile the thing on my raspbian by installing the linux-headers. But it seems the drivers created during the install is for RT2870? o.O

can someone please help? thanks

mrjayviper September 13, 2013

Has anyone got it to work on raspbian? if yes, instructions please. thanks

nick September 8, 2013

running modprobe on it seems to have fixed it - connected ok now - hurrah

anon November 10, 2013

thanks Nick! (and ctheroux, of course ;)
I run "sudo modprobe mt7601Usta" at the end and it worked fine! so happy..., it was really doing my head in.
(needless to say that if your chip is of a slightly different version, you should modprobe the correct module..)

nick September 8, 2013

install proceeded ok using already altered files. device recognised and able to select network and enter password, but kernal panic consistently as it tries to connect

clementine July 28, 2013

This doesn't work in 13.04. I once saw an obscure link somewhere that the developers were working on getting it to work in 13.04 but I don't know when that will be or what. Unfortunately this doesn't work. :(((((

Using sudo modprobe rt5572sta kicked it in for me on mint 15. thx! http://ubuntuforums.org/showthread.php?t=2137428

Will this work with the raspberry pi rev 2? In search of dual band single that works.

Thanks

DoD January 4, 2013

It works for me up until the 'sudo make' step it says it cant find the directory

MrKaroshi July 30, 2013

Any solution for this one? Having the same issue.

Radek November 5, 2012

the drivers complies and installs OK, it's telling me that I am connected to the network, but still have no internet access. can't ping google and chrome won't even open. I am using ubuntu 12.10 64 bit. Any suggestion?

lang6 December 19, 2012

same issue as Radek . Compiled, configured, connected, wpa auth ok but cannot ping my router or have dhcp offer. Set as static, routes are ok with default route using wireless device ra0 .Seen from my router interface as authenticated, so communication seems ok but cannot ping my router despite answer to ping are allowed on the router side

ctheroux December 24, 2012

The above does not work yet on 12.10.

Sharl January 15, 2013

Kelvin You December 11, 2013

Same issue. the DHCP request is sent out. but can not get the DHCP offer. Actually, the DHCP offer exists but dropped by the WiFi card.

no solution for this issue?

I've a venture that I am simply now operating
