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

[johnflux]

Hi all,

I'm am trying to get a fix put into the linux kernel. If this is successful, the RT2070 should work out of the box in Ubuntu 10.04. But I need your help!

If you have RT2070 or the Buffalo WLI-UC-GN usb-wifi device:

Please, install the kernel at: http://people.canonical.com/~smb/lp441990/

Specifically, do:

wget http://people.canonical.com/~smb/lp4...990v1_i386.deb http://people.canonical.com/~smb/lp4...1990v1_all.deb http://people.canonical.com/~smb/lp4...990v1_i386.deb
sudo dpkg -i linux-image-2.6.32-17-generic_2.6.32-17.26+lp441990v1_i386.deb linux-headers-2.6.32-17_2.6.32-17.26+lp441990v1_all.deb linux-headers-2.6.32-17-generic_2.6.32-17.26+lp441990v1_i386.deb


And then tell me if your hardware works.

I CANNOT GET THIS FIX UPSTREAM IF NOONE TESTS IT AND TELLS ME!

.. just in case it's not obvious, sorry, you need to reboot after doing the two instructions that I said, and then boot with that new kernel 2.6.32-17. The device should then just work - you should have a ra0 in iwconfig, and the device should show up in networkmanager.

archie888,
cp RT2870STA.Dat to RT3070STA.Dat - it is only config file. I belive it is beacose of buggy drivers. unlucky.

i tried to way you do, but it had not worked. anyway i found place and way how to add our id, but i do not remember where and how it was. find something like '3070', there should be something like
{0xID1, 0xID2} name.
once again: it did not make it.

johnflux, sorry but i wont use any of preconfigured kernels. my configuration is special for my eeepc made with hours of testing.

you can send me kernel source and say what should i change in my config. i'll then test it.

[johnflux]

It's just the stock ubuntu lucid kernel, with the USB_DEVICE line added.

[e-San]

Ok, i installed it.
It won't work, it won't boot. It halts on
'mounted root fs
can not mount /dev/pts and something else
cant mount rootfs'
???

anyway if your patch is:

#ifdef RT3070
        {USB_DEVICE(0x148F, 0x2070)},   /* e-San.info */
        {USB_DEVICE(0x148F, 0x3070)},   /* Ralink 3070 */

only - it must work.

archie888, why dont you try to compile your own kernel?
it can take not much your time (but compileing does)
- download kernel source (kernel.org)
- extract it
- copy your kernel config from /boot to .config into your kernel source
- make oldconfig (standard answeres to everything new)
- make xconfig - find staging in devices and enable rt3070 as module
- save
- apply my patch
- make -j2
- sudo make install modules_install
- add your new kernel to your grub/lilo menu.

I don't know. Is this on the EEPC? Does the ubuntu kernel normally work?

anyway if your patch is:

#ifdef RT3070
        {USB_DEVICE(0x148F, 0x2070)},   /* e-San.info */
        {USB_DEVICE(0x148F, 0x3070)},   /* Ralink 3070 */

only - it must work.

Yeah but I can't see that anyone has actually tried it, with the staging driver in the ubuntu kernel. Everyone is off downloading the awful driver from ralink etc. And you're telling people to use the stock linus kernel, which isn't helping things

[e-San]

Yes, it is eeepc.
Well i do not use ubuntu kernel, only mine. I installed 9.10 about month ago and it was working.
Few days ago i moved everything to other hdd (ssd btw.) but it does find all my partitions with no problem.
I had not modified too much this os, so i can not find the reason why...

I tried this modification (i added patch for 'empty dmesg lines', will see if this helps - i made this after test if first modiffication helps) and it does definetly works.

Meybe some usb-over-the-net? i belive there is something like that...

edit. i put information about this modification on rc2x00's team forum, meybe they will add this to drivers source.

edit2.

Hi, once again.
There is something more. there is another one small issue:

san@eeepc:~$ dmesg | tail
(...)
[22660.020103] ===>rt_ioctl_giwscan. 3(3) BSS returned, data->length = 402
[22780.020084] ===>rt_ioctl_giwscan. 3(3) BSS returned, data->length = 402

data->length = 267

[23500.020122] ===>rt_ioctl_giwscan. 4(4) BSS returned, data->length = 571

In my case - every two minutes.
but there is solution:

1. Once again, lets go to linux-2.6.33.1/drivers/staging/rt2860
2. nano sta_ioctl.c
3. find and comment

/*      DBGPRINT(RT_DEBUG_ERROR,        #e-San.info
                 ("===>rt_ioctl_giwscan. %d(%d) BSS returned, data->length = %d\n",
                  i, pAdapter->ScanTab.BssNr, data->length)); */

4. save (ctr + o)
5. compile and enjoy!

ad.1 if you compiled it with bug, remove linux-2.6.33.1/drivers/staging/rt2870/sta_ioctl.o before compileing.
ad.2 for further reserch, source: https://bugs.launchpad.net/ubuntu/+s...ux/+bug/356807

These instructions worked for me (http://www.buffalotech.com/products/...ter-wli-uc-gn/)

John,
Using the Buffalo WLI Nfinniti (Ralink chip) your updated kernel packages for amd64 made it work out-of-the-box. There is something worth mentioning though, my on-board wireless ( Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)) would stop being able to associate after approx. 2 hours of continuous use. Sorry, can't give more details than that, but it doesn't happen on 2.6.31-20, and it happned twice on that later kernel. I also can't tell you if it happens with the Buffalo card, as I am returning it now that I realized it only does 802.11N in 2.4Ghz (it doesn't have a 5Ghz radio). Great work on getting those Ralink chips to work.

[johnflux]

Thanks Mike.

This means Ubuntu 10.04 will ship with support for the Buffalo card
Unfortunately nobody tested with RT2070, so I can't get that fix in :-/
