if you go to


http://support.microsoft.com/kb/928233/en-us

it tells you how to get round this problem by regedit to

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{GUID}

and adding a key

my question is how do I work out what the  GUID  is of the network card

my mac of the usb wireless stick is

ZyXEL G-202 Wireless USB Adapter

Yes
Yes
fe80::cd40:4c0a:95ec:e4dd%10(Preferred)

08 April 2007 20:56:14
192.168.1.1
192.168.1.1

these are the guid's
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{0f694452-6a70-11db-8eb3-806e6f6e6963}HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{2c40b21f-b5c2-11db-a647-000c76bf5189}

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{AD10F175-FCEB-4446-9011-2E8D200A5FE4}
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{B1A58B1D-607D-4AD2-8976-79B2BC3EC94F}

nothing seems to correspond in the driver details
btw mine connects fine but I want to know for future reference I had to tie
down someone's wireless card to the router to get is to connect

This KB article mentions also another registry value,  DhcpConnForceBroadcastFlag,
that is global. If you set it, does it help?

you mean

MORE INFORMATION
If the router or the non-Microsoft DHCP server does not support the DHCP
BROADCAST flag, you can set the following registry entry as follows:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{GUID}

Value name: DhcpConnForceBroadcastFlag
Value type: REG_DWORD
Value data: 0

it still applies to a specific GUID

Yes. You're right.

The question regarding how to identify correct GUID...



If when connected you browse through the GUIDs in the registry (the list you suppplied), you can see which has a content that matches your adapter - You can find the IP for instance..



BTW. Setting DhcpConnForceBroadcastFlag to 0 worked for me.

Change all of them it does not matter you are having the problem with all adapters as I am.  This is a Vista problem that has no solution yet that I can find.  Static IP is the only way for now.

I've been working on my roommate's computer all damn day because I get this "Event ID 6100: Wireless association failed due to an unknown reason" crap when I try to connect to my own home network. I have an Dell Inspiron 1520 running the latest Windows Vista 32-bit, and I can connect sans problems to my wireless network at the house. But for some reason, his is just messing up, and I don't know why. I'm pretty resilient and resourseful, but not a tech geek. I'm wondering if anyone has any idea wt* is going on. Here's his PC's particulars:



--HP Pavillion dv2700 Notebook PC

--AMD Turion 64 X2 TL-60 processor @ 2 GHz

--4.00 GB RAM

--Windows Vista 64-bit SP2

--Broadcom 4321AG 802.11a/b/g/draft-n Wireless Adapter



and now the error particulars:

I have been to some of the following URL's for help, but none of what they offered helped at all:

http://www.vistax64.com/vista-networking-sharing/113627-stubborn-wireless-connectivity-problem.html



The one regarding the {GUID} parameters is a no-go, because in his registry there IS no {GUID} string, only {1ede8f65-4e0e-49e6-922e-339c09842320}, {c328fed4-6a85-11db-9fbd-806e6f6e6963}, and {f4db94a2-b556-4088-8ad0-29b7b7a0131f} strings. I'm going to include the contents of thise as well but have screenshots (I'm not about to copy down all of that information longhand).



Any ideas?? This problem JUST happened and it's got me bummed. Thanks ahead of time.
