I want to know which type of authentication is configured on APs that are
listed in
OID_802_11_BSSID_LIST

I have checked Information Elements it is comming according to IEEE
802.11-1999 specification.

so there is no specific IE for WPA or WPA-PSK.

As specified in IEE 802.11j-2004 Element id 48 specify it but I do not get
that ID at all.


So my question is how to know what type of authentication specificAP( Access
Point) supports?

I got following log for AP having WEP configure

SSID: DATA AP3
Interval 64 capabilities : ESS,CF Pollable,WEP:(0x15)
Variable IE length 0x1a
ElementID 0 : "DATA AP3"
ElementID 1 : 82:84:8b:96
ElementID 2 : 00:00:00:00:01
ElementID 3 : 06

AP having WPA-PSK

SSID: VOICE AP1
Interval 64 capabilities: ESS,WEP: ( 0x411)
Variable IE length 0x33
ElementID 0 : "VOICE AP1"
ElementID 1 : 82:84:8b:96
ElementID 2 : 00:00:00:00:01
ElementID 3 : 0b
ElementID dd :
00:50:f2:01:01:00:00:50:f2:02:01:00:00:50:f2:02:01:00:00:50:f2:02

what is Element ID 0xdd means?

2. Trouble connecting to WPA-PSK access point 

I have a D-link AirPlus DWL-G510 in a desktop running Windows XP Professional 
SP2, with all of the updates current. I'm trying to connect to an HP Procurve 
Access Point which has been set up with WPA-PSK encryption. Other desktops & 
laptops (newer) are able to connect using the key but this one doesn't seem 
to want to connect. It just keeps attempting and then says it cannot connect, 
contact your system administrator (which is me).

I have tried it at another location and it works fine with WPA-PSK 
encryption so I know I've got the software updates OK. I tried uninstalling 
the card, downloading the most updated driver & setup file from D-link and 
reinstalling.

I don't know what else to do at this point. Any help would be appreciated.

4. WPA PSK vs WPA Personal (D-Link products) 

I'm trying to get a couple PC's to connect to our WLAN.  The cards I 
installed (D-Link DWL-D520M's) can handle WPA PSK.  My AP's (DWL-2200AP's) 
can handle WPA Personal (and several others).  Right now I can't connect to 
the WLAN and I suspect it's because of the security settings.  At present I 
have WPA2 Personal on the PA's and wireless router.  Which setting on the 
router and AP's will be compatible with WPA PSK?

At the moment, my wireless encryption is WEP. As I read through your posting 
( Lanwench [MVP - Exchange] 1/17/2009 6:48 AM PST ) may I know what are the

Hi everyone, I have 2 desktop XP computers that are connected to my router 
and use WPA-PSK encryption. I also have 2 laptop computers that I just 
acquired and need to connect them to the same router but they only have 
wireless USB devices that support WEP... Can I get around this atall and 
still connect them to the router or will I have to change the encryption to 
WEP from WPA-PSK?.. or buy new USB sticks that support WPA-PSK? I was hoping 
that i could connect them but they will not be using WPA-PSK ?? I dont know!! 
Can anyone help? sorry if this sounds complicated. Thanks, Matt320
