Please help: rt2800 no scan results

[getWireless]

Hi,

I used suse for a while but still a newbie. I just installed suse 11.2 and for some reason I just can not get my wireless connection. I've already run the setup script in the sticky post. Please see the attached file. Can anyone help me get my wireless connected? I really appreciate your help!

Before I runinto this forum, I searched a lot with no results. The problem could be that the chipset rt2800 has no scan results. However, suse correctly identified the wireless usb card, and installed rt2800 module. It just can not get any scan results. I setup my router correctly, and no problem in windows with the wireless connection. (Don't get me wrong, I love linux. ) I tried no encryption, still no luck. Thank you very much for your help.

You have two drivers loading for this card, the rt2800usb and rt2870sta. I don't have any direct experience with this card, but usually when multiple drivers load, none work. Remove one of the drivers and see if it works.

sudo ifconfig wlan0 down
sudo modprobe -r rt2870sta
sudo modprobe -r rt2800usb
sudo modprobe rt2800usb
sudo ifconfig wlan0 up
sudo iwlist wlan0 scan

Thank you very much for your prompt reply! I run all the codes and still "wlan0 No scan results". Thanks.

after I remove both drivers, do I need to install one? Thanks.

by the way, I need to add /sbin/ to the first 5 codes, and have to "su" and then run the last code. Not sure if it matters.

I thought opensuse used sudo by default. All should be run with root privileges. If suse doesn't use sudo, you can log in as root to run.

su -

Post the output of

dmesg | grep wlan0
dmesg | grep rt28

You can also try removing the rt2800usb module and trying the rt2870sta module instead. The sta bit means it's in the staging tree, which houses drivers that are unfinished or the code quality isn't there to include in the mainline kernel.

Thank you. Here is the results:

If I remove 2800usb and use 2870sta instead, I got:

ifconfig wlan0 up
wlan0: unknown interface: No such device

After reboot and use 2800usb, I got the following message:

dmesg|grep wlan0

and

Any suggestion about what I need to do next? Thanks.

I have a USB wireless with what seems to be the same chip

148f:3070 Ralink Technology, Corp. RT2870 Wireless Adapter

It works perfectly using the rt2870sta driver. You should remove and blacklist the rt2800 and rt2x00 modules.

Thanks for your suggestion! I tried:

sudo /sbin/ifconfig wlan0 down
sudo /sbin/modprobe -r 2800usb
sudo /sbin/modprobe -r 2x00usb
sudo /sbin/modprobe -r 2870sta
sudo /sbin/modprobe 2870sta
sudo /sbin/ifconfig wlan0 up

wlan0: unknown interface: No such device

Then wlan0 is unknow interfact. Any suggestions? Thanks.

by the way, the card works in VM with XP on the same machine, so I guess the hardware and the network are fine.

Marry Christmas to you all!!

The problem lays in the fact that there are multiple modules that are interrelated. When one module loads, several others will load too. Removing just the one module leaves all of the others.

It is best just to blacklist the unwanted module. This then prevents all of the associated modules from loading too. The blacklisting is easily reversible, if it doesn't work. Just remove the line that you added. You must reboot after blacklisting a module.

I looked at my Ubuntu 9.10 system, and the firmware needed for the rt2800usb driver was already installed, so that may not be the problem. It still seems to be the fact that there are two driver modules loading for one device.

So, blacklist one of them, then reboot. If you still cannot get the wireless to work, remove the blacklisted module and add the other one.

The key is to reboot after blacklisting a module. This is a pretty major system alteration, and rebooting is the best way to get things straightened out.

Edit: I noticed that when you ran your modprobe commands, you didn't use the 'rt' part of the module. You must use the full name of the module:

rt2870sta
rt2800usb
rt2x00usb

Thank you for your reply! The "rt" part is just a typo when I post the code.

I just tried blacklist rt2800usb and rt2x00usb, and then restart.

It seems without rt2800usb, the os just can not recognize the wireless card. Not sure why, but when I googled, a lot of people's wireless card rt2800 can not be detected. After reading several pages of the following thread, I still have no clue.
