RT5572 Driver

[Dan9550]

I have got a new wifi usb stick that is based on the rt5572 chipset. although right now its useless because im having trouble finding and installing the drivers for it. If anyone could help that would be greatt

Did you not check here before purchasing ?

The RT5572 is not listed above but a Linux x86 driver is available, maybe you could create a driver for the ARMv6 architecture for other users who may have the same issue:

Could you post what /dmesg does?
I might be useful if there is an Invalid ****/**** in there somewhere (**** is numbers).

I recently fixed mine. The fix that I used is generic and works for, I think, all RT dongles.

Heres a dmesg output:

usb 1-1.2.1: USB disconnect, device number 5
usb 1-1.2.1: new high-speed USB device number 7 using dwc_otg
usb 1-1.2.1: New USB device found, idVendor=148f, idProduct=5572
usb 1-1.2.1: New USB device strings: Mfr=1, Product=2, SerialNumber=3

I have a RT5572-based USB adaptor (a TeckNet dual-band one from Amazon) working now on my Raspberry Pi. Getting it going involved a lot of tries including building a kernel from scratch, but this might not be necessary if you know how to build a device driver against an pre-existing kernel.

From what I can glean from my typing history, this is what I did:

1. change the WPA supplicant and other things in the Ralink driver sources as per http://www.ctheroux.com/2012/09/ralink- ... untu-12-04. Not everything needs to be changed now, some things are already present in the downloadable drivers.
2. get the latest RP kernel sources using “git clone --depth 1 https://github.com/raspberrypi/linux.git”
3. get the tools using “git clone https://github.com/raspberrypi/tools.git”
4. build the kernel using the config from “zcat /proc/config.gz” (I cross-compiled it on a PC as 20 minutes waiting is better than 6 hours)
5. install the kernel.img and modules and reboot using them
6. clean the tree you just built the kernel from
7. create a folder called “build” in the modules folder you just created, e.g. 3.6.11+
8. copy the cleaned source tree to that folder
9. build the RT5572 drivers, they will find the necessary kernel sources. The build takes many minutes on an RP
10. sudo modprobe rt5572sta
11. ifup ra0 (add this to /etc/rc.local)

Then finally:

pi@raspberrypi ~ $ # none of this would be here without the RT5572 working, as there is no other network connection

Hello All,

Worked for 2.4Ghz but on 5Ghz they don´t receive IP and if I put static, don´t work either.

Any hints ?

Thanks.

[tghewett]

Even scanning for other stations doesn't work for 5GHz, I also only managed to get 2.4GHz working.

Hello.
Is there a chance I could have a copy of your image you are using on your SD card with the RT5572 driver already compiled in?

thank you.

I am new to this forum so I don't know if this is a good place to post this information or not but I thought it might be useful to someone. I also am not sure how to format this post so I hope it looks OK. I have a TP-LINK TL-WDN3200 USB adapter which is based on a Ralink RT5572 or sometimes a RT5592. Mine is a RT5572 and with the latest version of Rasbian the Ralink RT2800USB driver is automatically installed but the adapter would only work on the 2.4 GHz band and would not scan or do anything to indicate it even had 5 GHz capabilities. I also use this adapter on a Windows system and I noticed that the default install of the driver selects the wrong region for the 5 GHz band (I am in the US region) and therefor would not work until set to the proper region. I researched how to change the region on the PI and found I needed to install a couple of packages, set the region for US and reboot, afterwards it now works on both bands.

Code: Select all

apt-get install firmware-linux-nonfree crda

Then change region

Code: Select all

iw reg set US

and reboot

Code: Select all

shutdown -r now

Scan for 5 GHz channels and they should be there.

Thanks, stijim.
I have a Rosewill RNX-N600UBE with the RT5572 chipset. Your post worked for me perfectly with Raspbian Jessie.

[guiboy]

same for me. the "apt-get install firmware-linux-nonfree crda" made it work smooth and nice on 5 GHz. Magic!
