Install linux drivers for ralink rt2870

[RaZoR1394]

What has rt2860 to do with rt2870? They are different. The first is the PCI version, the other USB. There is a reason different drivers are provided by Ralink.

Perhaps if you delete

#alias ra0 rt2870sta

it will automatically boot. I am not sure, though.

I changed my /etc/modules file to

fuse
lp
rtc
#alias ra0 rt2870sta
rt2860sta

but I still have to run sudo insmod rt2870sta.ko manually to get my wireless to work.

I did exactly the way that wangsuda said. I just simply added rt2870sta and it worked perfectly. It loaded automatically at boot

But, if for some reason, that doesn't work, try adding your insmod command (exactly the way you type it in the terminal without, but without the "sudo" prefix) to /etc/rc.local before "exit 0"

Hello - I just purchased the D-Link DWA-140 (ralink rt2870) and Jaunty beta picked it right up. However, the connection is showing only 54Mb/s and I have a "N" Linksys router set to mixed mode. Any ideas on how to increase the speed? I also finally got a linksys WMP300N working in both Intrepid and Jaunty beta and it will show 270Mb/s.

Thanks for any help on the D-link.

Ubuntu forums crashed...

I was mildly stunned to see that rt2870sta sets my speed to 54/Mb/s with both my Netgear WNR854T and my WRVS4400N router... It was usually 130Mb/s with the WRVS4400N and 270Mb/s with Netgear WNR854T on Jaunty alpha, but I'm on beta now. I need to investigate...

I never get speeds close to 270Mb/s... It's very rare you get over 50% of the set speed. Usually people who use 802.11n draft 2.0 300Mb/s don't reach over 100Mb/s.

I managed to reach 8MB/s by having the router just a few meters away. Usually with my current distance I reach about 4-6MB/s. I have two RP-SMA antennas that can be twisted and turned and I think it could be of some help.

Usually the best approach would be to skip USB and go for miniPCI, PCI or PCI-E. It's a cleaner solution. Usually these cards come with three antennas.

ok very nice!!! its installed but there is a problem:

the wireless adapter is 'unmanaged' and i cant change the mode from 'auto' to 'managed'

see this:

mauro@mauro-laptop:~$ sudo iwconfig ra0 mode managed
[sudo] password for mauro:
mauro@mauro-laptop:~$ iwconfig
lo no wireless extensions.

eth0 no wireless extensions.

I managed to get 130Mb/s set with my Linksys WRVS4400N after fiddling with /etc/Wireless/RT2870STA/RT2870STA.dat

Actually what I did was to try and install the new driver from 20090302 but it resulted in high instability so I had to revert to the old one (provided with Ubuntu) but kept my new .DAT file.

20090302 crapped out for me very badly so I have to stay at 1.4.0.0 until I've found the cause.

I'm having the same issue with a ralink 2870 and a fresh Jaunty install.
It finds the card and works without any additional driver compiling/installing however it maxes out at 54Mb/s. I achieved much higher with the same card and Intrepid (though I had to compile and install a driver as above)

-- EDIT -- I followed someone else's instructions to download the new ralink driver from their website: http://www.ralinktech.com.tw/data/dr...A_V2.1.1.0.tgz
Extract to a folder, enter the folder and 'sudo make', 'sudo make install', reboot and voila. It's connecting to 5Ghz networks at 300Mb/s.

This is a very helpful instruction. My dwa-140 never worked in ubuntu 8.1 but worked immediately in 9.04 after I followed your procedure. Thanks a lot
