Tenda W541U V2.0 Wireless USB Adapter / Ralink RT2070 How To

[lesnoland]

I think you are trying to modify a different version of the drivers, as Ralink keeps updating them. Please check in the first pages, I think there is a link there to the original driver this tutorial was designed to work with.

Regards.

Update: Here is a link to the original driver:

The Tenda W541U v2 doesn't work out of the box on 10.04.

I have followed the instructions from the first post but I fail at step 3 as below. I find no reference in the file to RT3070 or any similar line so don't know where to put the line.

It would be much simplier if Ralink chipset wifi deviced worked out of the box.

#cd 2009_0525_RT3070_Linux_STA_v2.1.1.0/os/linux
#pico usb_main_dev.c
...
add:
{USB_DEVICE(0x148F,0x2070)}, /* Ralink 2070L */
under #ifdef RT3070

It just worked! I downloaded all three files (kernel image and headers) and installed. A re-boot with the modified 2.6.32-17 kernel and my wireless came alive.

Thank you for providing this to the community.

Hmmm. I have tried the instructions in the first post but the make fails. Initially this was because gcc was not installed but now I get:

make *** /lib/modules/2.6.32-22-generic/build: No such file or directory. Stop.

I am running a new install of xubuntu 10.04 on an IBM R31 with 256MB RAM as a hobby project, so not that urgent, but I am confused by this. I figured it might be because I need the kernel source and downloaded that but no build directory appeared.

I am also confused by the patch. When do I run the patch code? (assuming I can get the make and make installto work).

[lesnoland]

you need to install the kernel headers (the kernel source is not required):

apt-get install build-essential kernel-headers-$(uname -r)

if it still does not work, try to find some info about building a kernel module, you can easily find it on google.

you run the patch code after you unpack the archive.

Hi.
After compiling four different Ralink drivers (kernel modules) I was able to get 2 of them fully working with my Ralink 2070 wifi. I am using kernel 2.6.32. None of Ralinks drivers had the correct usb IDs I needed (148F:2070) this had to be added. Blacklisting of rt2800usb was also required. The two drivers that worked were:

1) 2009_0525_RT3070_Linux_STA_v2.1.1.0 : This driver is no longer available from Ralink. This driver is well documented in this thread the, "rt3070-2.6.31-compile.patch" still worked with the 2.6.32 kernel.

2) DPO_RT3070_LinuxSTA_V2.3.0.2_20100412 : This is a later driver available from Ralink This compiled for me with no errors without patching. just A) Make clean-- to clean up the junk, B) add your USB ID into "/commom/rtusb_dev_id.c" and C) Make -- compile the driver. The rt3070sta.ko is built into the /os/linux directory.

I also tried 2 RT2870 drivers but was not able to get them fully working with the 2070 hardware.
Keep having fun

I've successfully installed the latest ralink driver (DPO_RT3070_LinuxSTA_V2.3.0.4_20100604) on kernel 2.6.34, but I'm getting this error with 2.6.35:

Any ideas?

i have the same trouble with 2.6.35 kernel (.
please post here if someone solve this problem.

It seems that they renamed usb_buffer_alloc and usb_buffer_free in 2.6.35 into usb_alloc_coherent and usb_free_coherent. Attached is a patch which fixes the compile errors. Let me know if the driver works for you now!

(driver version: DPO_RT3070_LinuxSTA_V2.3.0.4_20100604)

[Amazing-q3]

it works. thank you.
