Vista - Vista 64 cant detect my wireless network

I'm having big problems with my PC (running vista ultimate 64) detecting any available network. I'm having to use my second PC which is XP to
connect to the network to write this and having splashed out on a uber machine to play online thats pozzing me off.
Heres the story so far. In my old house I had both my PCs (XP-pro and Vista64 ultimate) connecting to my wireless network without problem.
Moved to a new house and the ISP provider sent me a new WIFI gateway (netopia 2247nwg, which is the same model as my old one) and therefore a new network to set up.
Set up my Xp PC with the SSID and WPA pass and it connects no problem. Yet my vista PC refuses to see any available networks, even if I power-up
the old router (which it used to detect and connect to).
Meanwhile trusty Xp detects both gateways.
In device manager my PCI WLAN adapter is showing as working 'it is a buffalo 802.11g using the broadcom chip'. As I could not get the cards drivers
to work with vista 64 (as there are no 64bit drivers available by buffalo) it defalted to the windows generic drivers that came with the vista installation
disc. It worked with these drivers at my previous house for over a year.
I've trawled the web for more time than I care to sacrifice and there are similar cases of vista not detecting networks but no solutions that have
helped me.

Tried:
netsh winsock reset
netsh int ip reset resetlog.txt
netsh winsock reset catalog
netsh int ip reset reset.log

turning off IP6 and link layer topology discovery

changed regedit (HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\ndisuio) start value to 2

made sure WLAN autoconfig is auto and started and all its dependancys

ran sfc/scannow in CMD prompt

...nothing worked and am still trawling for help.

Im sure all my hardware is good so my thinking is that this is a software issue.

Dont stop this is where it gets interseting..

Progress update..
Got fed up and did a system restore to an early working date. On reboot BSOD, then a report that a file was corrupt or missing and advice to repair
using install disk. This failed and I thought sod it I'll do a clean install. As vista wont install with 4gb of ram this ment dismantling a couple of coolers
to get at the ram... grrr
Anyhow vista installed no problem after that. And hey-presto my network was available, set up my wireless config and connected to the internet. With glee I
updated all my drivers with the PC rebooting and finding my network each time. Updated vista all the way to service pack 1, still have a connection.
Installed the most exellent game COD4 and tested it online.
Exellent, it took six hours installing and updating but I can look forward to a Saterdaynight of multiplayer mayhem.
Switched off PC, played with the kids, had dinner talked to the wife. And then got my self a cuppa tea and switched on my PC.
You guessed it, no wireless network detected by vista.

FEEL MY PAIN......

Let the knowledge flow people I'm getting desperate here..

You know, Ive been battling with a wireless network connection in Vista x86 and x64 for 2 years now. I am using a Netgear WG111v2 USB adaptor, which I know is a bit older.. But I get constant drops, and 50% of those drops from the network result in the inabillity to find a network connection.

The adaptor only connects to the network when plugged in one specific USB port, the other ones result in finding the network but being unable to connect.

Very frustrating. I could just upgrade my adaptor, I hear USB ones are not that great to use, but if anyone has any information on this as well Id appreciate it..

Did I mention my PC is a desktop and my adapter PCI..

Did an Ipconfig/all and then pinged my NIC heres the results:

Microsoft Windows [Version 6.0.6000]

After some messing about with swapping cards about etc I discovered my wireless card was not working properly even though device manager said that it was.
Result I bought a D-link airplus G DWL G520 which is compatible with both vista 32 and vista 64 installed and now everything is working fine..
