Using Windows Vista Wireless network gives LOCAL ONLY message stopping internet access

Since upgrading (now thats an arguable thing to say) to Windows Vista I've been getting this really annoying LOCAL ONLY error message when connecting to my Wireless network.   It allows me to connect to the network OK but i cant get through it onto the web. I can see all my local devices, log onto the router, but cant get outside the network ie: onto the world wide interweb superhighway net thingie

I've spent far too many hours of my life playing with DHCP, changing IP addresses, joining networks, leaving networks, running around finding an ethernet cable to get online so was delighted when I found a work-around for this wireless local only problem on the Microsoft website:  http://support.microsoft.com/kb/928233/en-us

So, the pointy-heads at Microsoft recognise that there is a problem with networking in Vista, which may be down the the fact that the DHCP BROADCAST is set to 0 in Windows XP but is different to Vista! Apparently this can cause problems with some wireless routers or acces points. I've just applied it so will report back on the on-going evil LOCAL ONLY problem....

Heres the Microsoft article. It's relatively simple to do you just need to be able to type accurately and use the CoRrecT CaSE where indicated: 

Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system.

To do this, follow these steps:

2.	Locate and then click the following registry subkey:   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{GUID} In this registry path, click the (GUID) subkey that corresponds to the network adapter that is connected to the network.
3.	On the Edit menu, point to New, and then click DWORD (32-bit) Value.
4.	In the New Value #1 box, type DhcpConnEnableBcastFlagToggle, and then press ENTER.
