Re: Having A Hard Time With Realtek Driver rt2870sta

How did you install the driver/firmware?
it could be that something you manually installed is conflicting with the already existing driver/files.

I have a

Code:

Bus 001 Device 002: ID 148f:3070 Ralink Technology, Corp

And all I needed to do was the blacklist rt2800usb , I did not have to install anything or mess with firmware.

have you tried blacklisting the sta driver instead? I have seen this go either way in my searches on this.

Re: Having A Hard Time With Realtek Driver rt2870sta

No I never even thought of blacklisting the sta driver, I will have to try that and see if it works.

How did I install firmware? I followed instructions, downloaded the firmware from http://www.ralinktech.com/support.php?s=2 and copied the .bin file I think it was into a directory after modifying the driver and installing it.

Now I've done a clean install of Kubuntu 10.04, blacklisted the rt2800usb, still no change after rebooting.

I found More info on the net so I downloaded and installed

http://packages.debian.org/squeeze/i...dc++5/download

Then Rebooted

Pasted the following commands all at once

echo 'install rt2870sta modprobe --ignore-install rt2870sta ; /bin/echo "1737 0078" > /sys/bus/usb/drivers/rt2870/new_id' | sudo tee /etc/modprobe.d/rt2870sta.conf
sudo modprobe -rf rt2870sta
sudo modprobe rt2870sta
dmesg | egrep 'rt28|usb|Phy'
iwconfig

then

sudo kate /etc/modules

I then added rt2870sta

then rebooted

Tada Same results, except I no longer get a warning after doing modprobe rt2870sta, I can successfully modprobe it now, everything seems to be there, but no wlan after I ifconfig.

Then I even installed the backports modules, still did not work after rebooting.

What I have learned so far from this is that the driver and the module were there already in Kubuntu 10.04, so like you said there is no need to install them.

I'm really not sure what to do now.

The Driver is registered, and I can modprobe successfully, I don't understand why I don't have wireless now?

Re: Having A Hard Time With Realtek Driver rt2870sta

You can modprobe a driver, but that does not mean the driver can recognize your device ID

I am thinking your device ID is not recognized as valid for the driver, which seems to be a relatively common problem for some usb wireless devices. Usually if a particular device ID is not listed but is known to be a valid one for the chipset, it used to mean recompiling some kernel modules.

this link pointed me to this one, which may be a solution here not involving a recompile

using the method in link #2, you would follow the instructions, except subbing
148f & 3070 for 1737 & 0078

the first section tests to see if it works, the second adds a new device rule to make it permanent, and it won't harm anything if it does not work

Re: Having A Hard Time With Realtek Driver rt2870sta

Hey Claydoh, I'm finally getting somewhere... Thanks for the awesome links, that was actually kinda fun.

The only thing I wasn't exactly sure about is the udev rules, because I don't have a wusb100 so I wasn't sure if I needed to modify the script other than changing my hardware numbers, so I didn't ! My end result here is that wireless is now detected under iwconfig and ifconfig rt2870sta, now when I go to Knetwork manager enable wireless is already checked and looks like everything works but when I click on scan for wireless connections it doesn't recognize my wireless signal, so even after I type it in along with my WEP key it still doesn't quite get on the internet.

The problem I see after iwconfig output is that all my Kubuntu computers will show ESSID "MyConnection"
and this one doesn't. So I believe that knetwork manager just isn't working with this somehow...

Here is what I did and my outputs:

Then I am posting a couple parts of the dmesg output, this looked strange

lana@lana1:~$ dmesg rt2870sta

I also get the same output if I blacklist rt3070sta

I also get all the info now when I ifconfig, and when I iwlist scan it does a perfect job scanning and gives good output. Now looks like it is not connecting to internet because it is not getting the hex key I put into KNetworkManager. and then still when I go to KNetworkManager and click on scan for new wireless network, it doesn't work, only works via command line...

unless I'm terribly mistaken this line
[ 622.758295] --> Error 2 opening /etc/Wireless/RT3070STA/RT3070STA.dat
says that the wrong firmware is not loading, I'm suspecting this could be a problem? since the file wireless doesn't even exist under the /etc/ directory... So Now I've Downloaded the rt2870sta.dat file, created the directory, rebooted, edited the rt2870.dat file, renamed it to RT3070STA.dat, rebooted again and "Yahoo" I now have internet, but KnetworkManager still doesn't do anything for me, I have to manually make any changes. is there some kind of network manager that may work with this ?
Also now after I shutdown and start back up again I have to "sudo ifconfig wlan0 up" in order to get internet working again.

Re: Having A Hard Time With Realtek Driver rt2870sta

This is how I got this Device to work. Thanks to Claydoh, and the links he provided, I was able to pull this off...

The Drawback to this Hack is knetworkManager will not do anything for you, You'll have to redo this for any kernel update, and it will cause your computer to lockup 2 out of every 5 tries, and after you boot-up the only thing you'll have to do is wait about 2-5 minutes for the wireless card to hook up, and if you need to change your WEP encryption key or network name, be prepared to do it by command line.
"After this I will never buy anything with a ralink driver again, as the company doesn't even provide the correct device ID's in thier drivers, or any support for that matter ". " I'm glad they have serious competition "

So here is all the information I gathered from all over the net, and this is how I got this usb stick to work.

Improve Backward Compatibility,

Download: http://packages.debian.org/squeeze/i...dc++5/download
Then install it by clicking on the .deb package you just downloaded.

(If you don't get an error code, scroll down about half way and continue to: "Part #2 "making the driver that comes with Kubuntu 10.04 work")

This means my rt2870sta driver was looking in the above named directory for the (firmware) RT3070STA.dat File,
So I Downloaded the rt2870sta.dat firmware that came with the driver from http://www.railink.com/support.php?s=2 , I downloaded "RT2870USB(RT2870/RT2770" I unpacked it and renamed the .dat file to RT3070STA.dat,

I edited the .dat file,

I found the above error interesting because /etc/wireless didn't even exist, then if you try to make
the directory all at once, you get more errors, So I sudo mkdir /etc/Wireless "hit "enter" then,
sudo mkdir /etc/Wireless/RT3070STA "hit enter"

Now that the directory was made, I ran the command: cd /home/jason/Desktop/rt2870firmware "hit enter"
type "ls" to list everything in that directory and "hit enter" and you should see the RT3070STA.dat file
Now: sudo cp RT3070STA.dat /etc/Wireless/RT3070STA

restart and run: dmesg rt2870sta and your error will be gone...
__________________________________________________ ____

Part #2 "making the driver that comes with Kubuntu 10.04 work / aka "Lets Hack the driver"

Is your Driver Loaded? if Not:

The "modprobe rt2870sta" command (as root) that you used before probably already loaded the version
provided with the kernel anyway. Now, this module "should" get loaded automatically once you insert the
wireless device. You can check this with the command "lsmod |grep rt2870" (as user). If not, then you
should add "rt2870sta" to the /etc/modules file with an editor.

Example: sudo kate /etc/modules
Then Press Enter.

Add the following text, at the end of the existing text:
rt2870sta
Save, Quit & Reboot.

After every Kernel update,run the following commands & hope they work, if they don't we'll be going back through this again.

sudo modprobe -rf rt2870sta
sudo modprobe rt2870sta
dmesg | egrep 'rt28|usb|Phy'
iwconfig

Now, the command (as root) "iwconfig" should show a wireless interface; the command (still as root)
"sudo iwlist scan" should show your own wireless access point. Network-manager is probably already installed,
so click on its icon in the right upper menu bar and select your access point and provide the password, if it works.

you may also need to reboot, if it still doesn't work don't be so surprised, please continue...

__________________________________________________ ____
__________________________________________________ ____

Most problems with the wifi drivers is that even thought they are supposed to work with your device,
this is why they don't, because the vendors change the hardware numbers and then they don't provide any support, yet they probably expect people to buy their stuff even though they don't even support it.

This is how I Skipped having to build or compile my own module / driver,
instead Recompile & Pass the correct ID Parameters to the module / driver:

I Gathered Hard Info:

lana@lana1:~$lsusb:
Bus 001 Device 003: ID 0411:016f MelCo., Inc. ( now notice "0411:016f" and where I used these numbers below )

Code: you can modify this code if you need to, then copy and paste it right into your terminal.

echo 'install rt2870sta modprobe --ignore-install rt2870sta ; /bin/echo "0411 016f" > /sys/bus/usb/drivers/rt2870/new_id' | sudo tee /etc/modprobe.d/rt2870sta.conf
sudo modprobe -rf rt2870sta
sudo modprobe rt2870sta
dmesg | egrep 'rt28|usb|Phy'
iwconfig

Ok, you are going to want the drive to load at startup

Code:

echo rt2870sta | sudo tee -a /etc/modules

reboot, then if you still have no internet, ( don't be surprised) please continue and modify udev

Knetwork manager should be up and running by now, if it isn't, reboot and give your computer a minute or two...

Now even though KnetworkManager is up and running, don't expect it to do anything for you, you'll have to edit the .dat file by hand to make any changes.

"This is a Hack, it makes the usb adapter work, but it is still not right.

I just finished another 2 days trying to make it right, finally it will be returned tomorrow, because today I Stopped at best buy, Bought a Netgear WG111v3, did a clean install of my Kubuntu, did all the updates, plugged this WG111v3 in, I noticed immediately that the lights came on, by the time I got the screensaver off knetworkmanager was working, I put in my info, and I was on the internet. I highly recommend the WG111v3 to anyone with Linux as it is truely plug and play, I am currently running Kubuntu 10.04 , I hope this atleast helps someone, as I believe the hack above should work for any wireless card, as a hack.
