Windows Vista being new has many issues. One of the biggest issues is the failure to get ip address from DHCP due to Vistas new DHCP implementation. Since editing the registry and determining the adapter through GUID to apply the registry hack to fix the problem can be a pain for some. I wrote a small tool to make it easier for people to fix the problem...download it here..

To use the tool is simple

1. Click on "Query Adapter" to get the list of network adapters in your systmer

2. Select the adapter you wish to fix. Reboot your system and see if you can get an IP from DHCP.

3. If you wish to undo the fix, select the adapter and choose "Reset to Vista Default".

Download it HERE.

the only weird wireless issue i get is that sometimes my system doesn't renew it's DNS.

I take my laptop to work where it's get assigned a specific IP each time but then i put the system to sleep and come home and it gets an IP at home from my router but it doesn't get it fully. I have to do a ipconfig /release and /renew for it to get it. At home the DNS is 192.168.1.1 of-course but at work it's another and for some reason it just doesn't change as it should. Only noticed this recently because i was using LAN at work and Wifi at home. I don't have this problem then.

(another problem is that when i come home and just open my laptop and it auto connects as it should, about 1 minute later it shows disconnected but it's actually still connected. I gotta manually disconnect and then connect for the icon to show it's connected)

sorry for the copy & paste, i'm just lazy

this is the problem I'm talking about:

One of our customers bought a Dell Inspiron (dont remember the model) with Windows Visa Premium on it.

At the house they have a Sonicwall (dont remember the model either) with WIFI.

WIFI security is set to WPA-SPK and I have the key.

The laptop sees the secure network.

I clicked connect and typed in the password -- it took it -- but then it either gives an IP conflict error or just wont obtain one. Other XP laptops worked fine. Everything is set to dynamically obtain and the DHCP range is big.

I tried repairing the connection - failed

Tried disabling the adapter and re-enabling - failed

Made sure there are no firewalls

Tried rebooting the router

Tried static IP

Tried recreating the connection

Everything has failed. The status keeps saying that its trying to identify the network.

Weird thing is that sometimes it connect but after rebooting -- same problem

You can see its trying to get an IP and sometimes it does for a second and then looses it.

I have read about similar problem with Vista.

Is there a solution?

Hit my first bug when I got back. My Intel pro 2200 BG wireless connection was not getting DHCP lease from my IPCOP server. The weird thing was that my LAN card was fine and my wireless connection worked fine if I used a static IP.

Spent a whole night trying to feagure out the problem.Good news is I manged to fix it with some help from MS knowledgebase and a few registry tweaks. It seems to be a problem with the BROADCAST flag in DHCP discovery packets. In XP it?s off and in Vista it?s on. Non Microsoft DHCP servers don?t like this.

See the fix on the next page;

1. Start ?> run ?> regedit.exe

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

3. {GUID} sub-key refers to the network adapter that is having the issue. In my case my Intel Pro 2200BG card.

4. Add a new DWORD (32bit) value and rename it to ?DhcpConnDisableBcastFlagToggle?.

5. Modify the ?DhcpConnDisableBcastFlagToggle? key and change the value to ?1″.

6. Modify the ?DhcpConnForceBroadcastFlag? key and change the value to ?0″.

7. Reboot and test the connection again with DHCP. (The reboot is optional)
