Problem get WPA working on Edimax EW-7128g

Hello RT2500-Users,

I've installed driver version "rt2500-1.1.0-b3" and have problems to get WPA working. This is what I tried to do after loading the module:

Code:

ifconfig ra0 up
iwconfig ra0 mode managed
iwpriv ra0 set AuthMode=WPAPSK
iwpriv ra0 set EncrypType=TKIP
iwpriv ra0 set WPAPSK="MyPassword"
iwconfig ra0 essid "MyModemsESSID"
dhclient ra0

Networking seems to be established, but I cannot reach the Internet or the Web-Interface of my modem.

WEP works fine for me:

Code:

iwconfig ra0 key xxxx-xxxx-xxxx-xxxx-xxxx-xxxx-xx enc open essid "MyModemsESSID"
dhclient ra0

Did I forget something? Could this be a bug? How could I help you to fix this problem? (I unfortunately have no skills in coding)

Max

There is a known problem with WPA keys not apparently being excahnged properly the first time the interface is ifup'd. Try doing an ifdown after the first ifup and then ifup again.

If that doesn't work there are a group of us generating debugging on this issue at present, so it may be fixed soon.

Some results of iwconfig, ifconfig, iwlist <iface> scan would be useful.

Can you give more details of distie and kernel etc just to be sure.

You mean:

Code:

ifconfig ra0 up
ifconfig ra0 down
ifconfig ra0 up
iwconfig ra0 mode managed
iwpriv ra0 set AuthMode=WPAPSK
iwpriv ra0 set EncrypType=TKIP
iwpriv ra0 set WPAPSK="MyPassword"
iwconfig ra0 essid "MyModemsESSID"
dhclient ra0

O.k., but now I'm running with WEP, it takes some time but it's time to go to bed for me :-)

, I will do that tomorrow...

Bad luck for me - this trick didn't work for me :-(

Any suggestions? Or do I have to waint until a new driver will be released?

Do this.

iwconfig ra0 mode managed
iwpriv ra0 set AuthMode=WPAPSK
iwpriv ra0 set EncrypType=TKIP
iwconfig ra0 essid "MyModemsESSID"
iwpriv ra0 set WPAPSK="MyPassword"
ifconfig ra0 up
sleep 5
dhclient ra0

No luck with this either.

I typed in the commands in exact your proposed new order + "sleep 5" - same result :-(

serialmonkey · **Posted:** Mon Aug 29, 2005 10:26 pm

Please provide a debug trace of running the commands above.

You mean building a new module with

Code:

make debug

and loading it with

Code:

modprobe rt2500 debug=1

???

Or is there something else I have to do to enable debugging with ALL the commands?

serialmonkey · **Posted:** Tue Aug 30, 2005 10:48 pm

As per the Module\TESTING file (what you have above is correct)

Hi there,

this is what I did:
loading the module with

Code:

modprobe rt2500 debug=1

Then I ran following commands in a script:

Code:

iwconfig ra0 mode managed
iwpriv ra0 set AuthMode=WPAPSK
iwpriv ra0 set EncrypType=TKIP
iwconfig ra0 essid "Max-Box SL WLAN"
iwpriv ra0 set WPAPSK="DuKummstDaNedNei"
ifconfig ra0 up
sleep 5
dhclient ra0

The last thing I did was:

Code:

grep "kernel: rt2500" /var/log/messages > RaLink_debug.txt

The attached file is the result, 1,4MB size!!!!!!!
Is this normal when debug-mode on?

Quite, which is why most people gzip them before posting, and why it takes awhile to analyse them. I'll have a read now.

Okay, somehow, the interface is up before you set all that. You can see at line 16480 is where you set the ESSID - the driver has been up for at least 30 seconds before that. Something autoupping it on your behalf ?

But, you do successful associate and auth at 17120. We recieve the first WPA EAP handshake at 17154 and the third at 17212.

From there on I can't spot any problems (though I don't have my working debug sample handy). I'd start by working out what is upping that interface on you.

OR

Rerun the test and provide me another debug where the first thing you do after modprobe is 'ifconfig ra0 down'

What I did to bring the network down was:

Code:

service network stop

This hopefully should do the same thing, doesn't it? Or do I have to bring it down every time AFTER I am modprobing? Isn't the network already down then?

I was modprobing manually, and after that (perhaps 30sec???) I ran the script. Maybe it has something to do with this?
I don't think that something is done automaticly beside booting.

Well, weekend is near and perhaps I provide you with a new debug-info if necessary.

Hello all,

back again with a new debug-message - now I've added the line "ifconfig ra0 down" to my script and it looks like this:

Code:

ifconfig ra0 down
iwconfig ra0 mode managed
iwpriv ra0 set AuthMode=WPAPSK
iwpriv ra0 set EncrypType=TKIP
iwconfig ra0 essid "Max-Box SL WLAN"
iwpriv ra0 set WPAPSK="DuKummstDaNedNei"
ifconfig ra0 up
sleep 5
dhclient ra0

Gosh - the debug-text is now 3,6MB!!!!! But now I made a .gz-file.

Happy bug-finding - I wouln't find anything in all the lines...
