Ubuntu 10.04, Wireless chipsets, and WPA Security

Ubuntu’s latest release, 10.04, was officially posted this week. Overall, it is a very impressive effort and a milestone for the Open Source community. I have installed it on a new cheap desktop I recently built and it runs fantastically with fast boot times and nice desktop eye candy.

The one thing that spoils this effort is the continued hassles in getting wireless wifi cards working. I have a half dozen usb wifi sticks lying around and only one just works our of the box. I guess it wouldn’t be Linux if one didn’t have to at least compile a driver or two every now and then?

Anyway, I recently purchased the Asus PCE-N13 IEEE 802.11b/g/n PCI Express Wireless Adapter.

I bought the card on sale for $19.99 and on the basis that someone left comments that it worked in Ubuntu 10.04. Not sure what this fellow’s definition of working is but it doesn’t just work at least when you use WPA security. So, determined not to let this get the better of me, I embarked on a flurry of google searches.

This card uses the Ralink RT2860 chipset which is used in many products. The problem from what I’ve been able to determine is that the WPA source code definitions are wrong by default. It’s not clear why this is so but that seems to be the case. The fix and ultimate configuration is fairly straight forward if one can find clear and accurate instructions. There’s the rub.

I finally stumbled upon some good instructions but maddeningly they contained key errors that will surely frustrate the uninitiated. So, in the interest of helping those that follow, I offer my amended instructions that I have tested and believe to be accurate. With this guide you should be able to get a Ralink RT2860 based product running and connected to a secure router running WPA security and will do so after reboots.

The following steps were performed on a unmodified default Ubuntu 10.04 final code install.

Step 1
Download latest RT2860 driver source code from Ralink here. You need to enter a name and an email and press accept to download.

Step 2
Open and extract the downloaded file to a temporary directory in your Home directory.

Step 3
Using an editor such as the default Gedit, open the driver source code file ./os/linux/ Use the find command to locate HAS_WPA_SUPPLICANT and make sure it is set to yes. It should look like this when finished:

and do the same for:

Close and save this file.

Step 4
Using an editor such as the default Gedit, open the file ./common/cmm_wpa.c. Use the find command to locate MIX_CIPHER_NOTUSE. Replace this entire line (keep on one line)with this code:


Step 5
Perform these commands in a Terminal session one at a time. You can cut and paste. Using sudo puts you into Admin mode so you will be prompted for you Admin (probably) your default password.

sudo make
sudo make install
sudo ifconfig wlan0 down
sudo rmmod rt2860sta

Step 6
Rename the old rt2860sta.ko driver file to rt2860sta.ko.dist using a command such as:

sudo mv /lib/modules/2.6.*/kernel/drivers/staging/rt2860/rt2860sta.ko rt2860sta.ko.dist

Note you need to replace the asterisk with the actual directory name of your kernel. Consult your file system directory structure for this.

This is to prevent the old driver from being used. You could just delete the file as well I suppose.

Step 7
sudo depmod -a
sudo modprobe rt2860sta

After you issue the previous command you should see the Desktop top panel Wireless icon come to life as it tries to connect. You will be prompted for a WPA password. Give it a little while and it should connect.

Not sure this command is necessary but you can use if the Wireless isn’t started automatically.

sudo ifconfig wlan0 up

Step 8
Okay at this point you have made a lot of progress and should be happily surfing at up to 802.11n speeds. Take a break and marvel at your skills and the wonder of the Internet!

Step 9
But, and this is a biggie, what happens if you ever reboot? Unfortunately, you are back at square one without the RT2860 driver being loaded after a reboot. To remedy this situation, read on.

Step 10
Copy the newly compiled driver from your temporary build directory in ./os/linux using a command like:
sudo cp rt2860sta.ko /lib/modules/2.6.*/kernel/drivers/staging/rt2860/
Again replace the asterisk with the correct directory name.

Step 11
Update your modules boot file with the following command:
gksudo gedit /etc/modules
Add the command rt2860sta on a line at the end of the file.
Close and save the file.

Step 12

Reboot and check to see that you are now automatically connecting to your wireless network!

I hope this tutorial may be helpful for some people.

Step 7

sudo depmod -a
sudo modeprobe rt2860sta

there is one small mistake (typo maybe) - the second line should be

sudo modprobe rt2860sta

Chris said...

Thanks for catching the "modeprobe" mistake. Now fixed!

Hi Chris,

Thanks for this perfect description. It helped me to get wireless working on my Netbook. Though I needed an ethernet cable to download gcc first :-(

One small remark. I don't think it's necessary to do step 11 (I skipped it and my wireless works flawlessly). The /etc/modules file is for modules you want to load at boot time. It's better to load the wireless kernel module only when you activate your wireless.

Stef said...

Hi, thnx for this step-by-step guide, I'm getting till step 5 though. (I haven't got much experience with linux, so I'learning now:)) The thing is, I don't understand what I have to do at step with the commands, because when I paste and run, I only get some useless output. I guess when I have to paste "sudo make" there should come something after "make", but I don know what...

Soooo, what am I doing wrong? xD

Chris said...

Hi Stef. I guess I assumed a little too much. When you open a terminal session. You need to change directory into the location where you extracted the downloaded driver files. You use the "cd" command just like DOS except you use a "/" to denote the directory. So if you extracted the drivers into your Home directory in a sub directory called "temp" you would use "cd /Home/temp" in terminal first. If there is an actual sub directory there (use "ls" to do a "dir") you will need to cd there as well. You will know you are in the right place when you see a file called "Makefile". This is the instruction file that gets read when you issue the "sudo make" command. Give it a try.


Anonymous said...

Hi Chris. Big thanks! After working a day at this problem I found your instruction - and it works perfectly!

Stef said...

Thnx! But now there's a second problem: I'm in the right directory, but when I run "sudo make" I get this

karien@karien-laptop:~/Documenten/2010_01_29_RT2860_Linux_STA_v2.3.0.0$ sudo make
make -C tools
make[1]: Entering directory `/home/karien/Documenten/2010_01_29_RT2860_Linux_STA_v2.3.0.0/tools'

make[1]: Leaving directory `/home/karien/Documenten/2010_01_29_RT2860_Linux_STA_v2.3.0.0/tools'
make: *** [build_tools] Error 2

... What is going wrong?

Chris said...

Okay Stef, I'm trying to help but you do need to do some research on you own ;) The message you are seeing is saying it cannot find your C compiler which is called gcc. Is this a fresh clean install of Ubuntu 10.04 from the final release ISO download you are working with? If not you may want to do a fresh install before you go much further. The default install to my knowledge always includes "gcc" but maybe if you are using an alternate install it is not included? Then you will need to install "gcc" or this is just not going to work for you.

Stef said...

10.04, latest release, netbook-remix and I installed it today.;] With gcc, as I can see in the software manager. So erm, I guess this is getting complicated...

Muppet Jones said...

Chris, great instructions! Thanks a bunch! Works like a charm!

Nick W. said...

Hey Chris - great guide. WLAN up and working now. Thanks very much - Nick UK

Dave said...

It works! Thank you! Although, for some reason I couldn't connect at step 7. I had to go through all the steps and reboot.

Arpita said...

Hi Chris..nice instructions..But facing a problem at Step 10.

HP-UBUNTU:~/Temp/os/linux$sudo cp rt2860sta.ko /lib/modules/2.6.*/kernel/drivers/staging/rt2860/ returns as
cp : cannot creat regular file 'lib/modules/2.6.*/kernel/drivers/staging/rt2860/': No such file or directory

I have also tried this step from root (may be there is a permission problem), but the error message remains the same...

Don't know what to do now...Please HELP !!!


Chris said...

Come on Arpita? Are you actually reading the instructions where I say "Again replace the asterisk with the correct directory name"?

Based on the positive feedback, I know these instructions will get you up and running. But, everyone has to do a little heavy lifting or at least use google to fill in your individual knowledge gaps.


Arpita said...

yes, yes...I know..

I have actually done this

HP-UBUNTU:~/Temp/os/linux$sudo cp rt2860sta.ko /lib/modules/2.6.32-21-generic/kernel/drivers/staging/rt2860/ returns as
cp : cannot creat regular file 'lib/modules/2.6..32-21-generic/kernel/drivers/staging/rt2860/': No such file or directory

But, no luck :(

There is some lock sign on the 'rt2860sta.ko' file icon. For this reason I have tried this command from root as well.

Thanks Chris.
On my system system (eeepc 1000), editing the /etc/modules file was not necessary.

You, my friend, are a saint. I've been cussing Ubuntu up one side and down the other for breaking this.

you made my day pal. thank you so much.

knnniggett said...

After previously reporting initial success, a new problem has developed.

Even though my wireless nic was able to successfully connect to my network, I could no longer transfer any data over it. The adapter would just quit transferring data after an initial burst. Some kind of buffer overflow perhaps?

After some Googling, I came across another potential solution:

sudo apt-get install linux-backports-modules-wireless-karmic-generic

This seems to have things resolved for the time being. You might want to try this if all else fails.

Meneer said...

hey thanks for this great tutorial.

I get this error with the modprobe command. "FATAL: Error inserting rt2860sta (/lib/modules/2.6.32-22-generic/kernel/drivers/net/wireless/rt2860sta.ko): Invalid module format

Also after I use the "sudo mv" command to rename the rt2860,sta.ko, the whole directory gets deleted instead of the file renamed . . .

Anonymous said...

Perfect. Not having wireless was a big disappointment. On my eeepc 901 I followed the steps exactly except for step 11. Now wireless works flawlessly. Thank you very much.

AmateurDev said...

After step 7, I still couldn't connect to the Internet. I tried "sudo ifconfig wlan0 up" but it replied wlan0: ERROR while getting interface flags : no such device. I went through the rest of the steps anyway and restarted. Then, I found out that the wireless interface is now named "ra0" so I tried "sudo ifconfig ra0 up." The error message didn't appear, but it still wouldn't connect. Obviously, other people can connect, so can you tell me what I did wrong?

skizzdc said...

Wow! Thank you so much! Looks like its working finally! I can't believe this was a problem, especially since Asus users are a large population of the Ubuntu Community. Nonetheless, I'm back in business. Thanks again!

AmateurDev said...

Never mind, I read your newest post on using the newest kernel, I'll try and see if that works

Anonymous said...

Thanks for your instructions. Worked like a charm! I wrote a little script to simplify installation in the future after a kernel upgrade. Maybe it helps others. Just place it in the root directory of the driver source, make it executable and run as root.

KV=$(uname -r)
MODULES=$(cat /etc/modules | grep -i rt2860sta)

# edit source code
cp os/linux/ os/linux/

cat common/cmm_wpa.c.dist | sed -e 's\FlexibleCipher = MIX_CIPHER_NOTUSE;\FlexibleCipher = WPA_TKIPAES_WPA2_TKIPAES;\' > common/cmm_wpa.c

# compile driver module
make install

# shutdown wlan interface
ifconfig wlan0 down
ifconfig ra0 down

# unload wlan kernel module
rmmod rt2860sta

# load and install wlan kernel module
mv /lib/modules/$KV/kernel/drivers/staging/rt2860/rt2860sta.ko /lib/modules/$KV/kernel/drivers/staging/rt2860/rt2860sta.ko.dist
depmod -a
modprobe rt2860sta
cp os/linux/rt2860sta.ko /lib/modules/$KV/kernel/drivers/staging/rt2860/

# add wlan module to /etc/modules if it is not already added
if [ $MODULES = "rt2860sta" ];
then exit;
else echo "rt2860sta" >> /etc/modules;

Hey Chris
Great post for this fix.
After an upgrade to 10.04 LTS on an ASUS 901, I followed your well written instructions and my wifi sprung back into life and even after the reboot. Saved me hours of hacking about. Many thanks.

Peter Campbell said...

Thanks for this information. It worked for me and saved re-installing Kubuntu 9.10 It seems the regression testing in 10.04 didn't pick this up and should have.

But a small complain about these bugs that don't let use linux out of the box. These makes many newbies coming from Windows run away. What a pity!

hmm. Aha. Thanks so much for posting this. My first attempt at making and installing a driver from source. A very helpful and friendly article.

However, after reboot, now wicd doesn't see the wireless networks at all. Before it could see them, but wouldn't connect.

Better start from scratch. Sigh.


michael chalk said...

ooh ..correction!

Wicd can't see any wireless connections, but via iwconfig i see that somehow the wifi card has in fact connected to the access point, and is happily pinging the gateway.


Now to figure out why Wicd has lost its enthusiasm.

I need your help to correct this error.

Could you please send me your RT2860 driver source code because i'have error when i decompress the files ?
Thank you.

Andrea Vallesi said...

The error "Invalid module format" occurs when the module has been built against a kernel that is not the currently running kernel.

Check the currently running kernel version with "uname -a" and if it is a .PAE kind, install the relevant kernel-devel with "yum -y install kernel-PAE-devel".

Is it possible that this might also work for RT2870 (with name substitution of course)?

Hi Chris,

Thank you for this guide. I'm finding it helpful in learning to use command terminal. I just installed Ubuntu 10.04 LTS a few days ago. This is my first time using Linux, so I'm just beginning to learn. On step 5, on the make command, I got the following warning several times:

warning: the frame size of * bytes is larger than 1024 bytes

I'm not sure what to do about this. I also got the following error messages:

CC [M] /home/deli/Temp/RT2860/os/linux/../../sta/wpa.o

I've spent a lot of of time researching and studying, seeking to figure this out. I appreiciate the challenge, but any help I can get on this would also be appreciated.

I got it. I figured out what I was doing wrong and completed the steps. My WPA connection is working fine now. Thanks again for this guide! It was very helpful. It's been a great learning experience for me.


P.S. Your link to download the Ralink driver package didn't work for me. After entering my name and email address, It gave me an error page. I navigated through the site to get to the download. You might need to update the link.

Thank you, thank you, thank you!!!
After much frustration trying to get up and running in "n" after finding that the native driver in Lucid did not allow this and much frustration trying to understand the "read me" file, my laptop is now "n" capable and "smoking"

Thanks you very much. I was having a hard time with WPA just like you. This was extremely helpful. Thanks again, much appreciated on the effort on this.

Thank you so much, you rock!

It's worth noting that even though the latest driver has the .bz2 extension, it's actually gzipped.

I executed

mv 2010_07_16_RT2860_Linux_STA_v2.4.0.0.tar.bz2 2010_07_16_RT2860_Linux_STA_v2.4.0.0.tar.gz

Before unzipping using tar -zxvf mv 2010_07_16_RT2860_Linux_STA_v2.4.0.0.tar.bz2

Hope that helps someone else.

The instructions worked for me pretty well, i just had to replace rt2860sta with rt3090sta since i guess both those drivers compile from the same source code. just us 'lspci' to see the exact chipset your card uses

Stacie said...

I really hate to post about the same problem, but I did not find the answer. You have probably the only published help on getting RT2680 working with Ubuntu.

I am getting an error when trying to complete step 5: sudo make:

make[2]: *** [/home/cag-media/2010_07_16_RT2860_Linux_STA_v2.4.0.0/os/linux/../../common/cmm_wpa.o] Error 1
make[1]: *** [_module_/home/cag-media/2010_07_16_RT2860_Linux_STA_v2.4.0.0/os/linux] Error 2
make[1]: Leaving directory `/usr/src/linux-headers-2.6.35-27-generic'
make: *** [LINUX] Error 2

I even researched and found that I may need GCC installed. It is.

Please help! I'm stuck!

I did get past those errors. Now this is happening:

sudo rmmod rt2860sta

ERROR: Module rt2860sta does not exist in /proc/modules

Any help would be appreciated.

Absolutely amazing!
Followed instructions step-by-step and now the built-in wifi card of my laptop is working.
Thank you very much for share this info!
(Laptop Medion MD96630; Wifi card chipset Ralink RT2860; Linux Mint 11).
P.S: I let the my laptop wifi button control blocked before erasing WinXP and installing Mint (due to this had 'SIOCSIFFLAGS: Operation not possible due to RF-kill' at end of Step 7; Solution -> Installed 'rfkill' application to unblock it under Linux).

I'm a bit new to linux. This fix worked for me before, but it stopped working and I read somewhere that updating the kernel with re-break the driver.

What steps do I need to repeat to re-apply this fix to the new kernel? Do I need to re-compile the driver (all of step 5) or can I start with "sudo ifconfig wlan0 down" part of step 5?

Also, if anyone has some advice on how to automate the process or simplify it to one click that would be amazing.

2 DoThoughts: use Stef`s automation script.

Thanks a lot to Author for his work.

This fix works perfectly in 12.04 as well. Thanks for posting it! After searching endlessly this is the ONLY fix I found that solved my problem!

Thank you for providing the link of the instruction that you discovered. I will try to do these steps and see if it will work for me.
