Wireless NIC can't Authenticate to AP using WPA; ndiswrapper/wpa_supplicant

patkalolo · 11-10-2004, 01:09 AM

Alright I give up..I need help:

Problem -

Wireless card cannot authenticate with AP.

Description -

I am trying to get my dlink dwl-g520 to connect to my dlink di-624 in Slackware 10.0, running kernel 2.6.9. I have the latest ndiswrapper installed as well as wpa_supplicant. The output of "ndiswrapper -l" is as follows:

Code:

Installed ndis drivers:
net5211 driver present, hardware present

Output of "iwconfig" is as follows:

Code:

IEEE 802.11g  ESSID:"makaha"
          Mode:Managed  Frequency:2.437GHz  Access Point: 00:0D:88:BC:4B:F3

          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

My "/etc/wpa_supplicant.conf" file reads as follows:

Code:

 ctrl_interface=/var/run/wpa_supplicant # for wpa_cli support

network={
  ssid="makaha"
  key_mgmt=WPA-PSK
  pairwise=TKIP
  group=TKIP
  psk="XXXXXXXXXX"
  proto=WPA
}

Output of ifconfig is as follows:

Code:

Entering "iwlist scan" outputs lots of info, most important of which is:

Code:

So to the best of my knowledge everything is fine. The proper drivers are installed, my wpa_supplicant.conf file reads correctly, but when I type in the command "wpa_supplicant -Dndiswrapper -iwlan0 -c/etc/wpa_supplicant.conf -dd" I get the following code:

Conclusion:
Apparently my wireless card will not authenticate to my AP. Any ideas??

This is a link that might help. There is a step near the bottom after the wpa_supplicant is listed , which may help. Or perhaps you did this and didn't indicate it.

patkalolo · 11-10-2004, 04:31 AM

You see the thing is that I do not have this directory at all:

"/etc/sysconfig"

I will explore further though.

2Gnu · 11-10-2004, 08:09 AM

You won't have /etc/sysconfig/anything in Slack. I read the link and the two references to that dir where to automate bringing up wpa_supplicant which you could do in /etc/rc.d/rc.wireless.

Unfortunately, I don't have the greater answer as to why you can't authenticate. Anything in the logs - /var/log/messages or the router log? Is the latest firmware running on the router and the wireless card?

patkalolo · 12-08-2004, 12:35 AM

Sorry I took so long to respond but I been poking at other problems because this one is just pi$$ing me off. So in any case I looked in my router log and it has the floowing info:

Code:

Dec/07/2004 22:18:05 	state: paeDISCONNECTED			
Dec/07/2004 22:18:05 	Wireless PC connected			XX-XX-XX-XX-XX-XX
Dec/07/2004 22:17:53 	Authentication success

Even when I look in the list of currently connected wireless computers there I am!! It seems that the card and the AP connect but Linux doesnt.

patkalolo · 12-08-2004, 02:39 AM

Alright so I didi a little more fidgeting. Here is the procedure i used:

Code:

ifconfig eth0 down
ifconfig wlan0
route add -net default gw 192.168.0.1
wpa_supplicant -Dndiswrapper -iwlan0 -c/etc/wpa_supplicant.conf -dd

I used the route command to get the gateway to 'wlan0 to be the same as it is when 'eth0' is in use.

Here is the funky output that I get:

Code:

You may have another wpa_supplicant process already running or the file was

to manually remove this file before starting wpa_supplicant again.

The last part is the most interesting. Anyone see anything?

Ha...

So I went into the configuration menu of my DI-624 router and made the IP of my DWL-G520 card static, and different from the Dynamic IP of my wired NIC. I previously attempted to use the same IP from the wired card (192.168.0.101) to bring up the wlan0 interface with the command:

Code:

 ifconfig wlan0 xxx.xxx.x.101

Now instead I am using the Static IP (192.168.0.111) assigned to the MAC address of my wired NIC to bring up the wlan0 interface using:

Code:

ifconfig wlan0 xxx.xxx.x.111

I think this was the main issue. Total PITA. In any case what follows is the steps that I have to use to get my wireless connection up:

Code:

ifconfig eth0 down
ifconfig wlan0 xxx.xxx.x.111
route add -net default gw xxx.xxx.x.1
wpa_supplicant -Dndiswrapper -iwlan0 -c/etc/wpa_supplicant.conf -dd

I still don't know why I have to set the default gateway that gets added to the eth0 connection automatically, but at this point I am just glad that I got things working. Now I just have to automate it.

patkalolo....... all I can say is THANK YOU SO MUCH!

I have been trying to get WPA working on my wireless linux boxes for literally months and months and months..... I got fed up of looking at the same damn instructions on all these web sites but none of them ever solved my problem which was that the linux boxes just wouldn't associate with my DI-624 even though the router was registering the linux box as associated! Every now and then I'd go back to it and have another go but never got anywhere - until now!!!!!!!!! Just got it up and running on my laptop using ipw2200 driver and it works fine! YES!

Thanks so much again, you are the man!
