Vista - WiFi Card will not find networks when > 2GB RAM

I have two PCI wireless network cards from two different brands, Netgear
WG311V2 and D-Link DWl-G520+.

My Vista Ultimate 32-bit SP2 system has 4GB of RAM.

Neither will detect wireless networks when the system RAM is greater than
2GB.
If I pull out one 2GB stick, it works fine. Put it back in, failure to see
networks.

I tried the Netgear on a Windows 2003 Standard 32 bit SP2 with 4GB of RAM
and it worked ok.

Any help?

Hi,

When you said "Vista Ultimate" and the "Win2K3", did you have those both
on the same physical systems, or are you talking about two different
physical machines?

If the latter, then many the one with Vista has bad memory? Maybe run a
memory test (memtest) on the 4GB RAM?

Hi
I doubt that it has to do with Wireless.
There are probably some problems with the computer and its accommodation of
the memory when the OS is Not capable to recognize all the memory.

The *full* 4GB of RAM is visible to the Vista 32 system and the 2003
Standard Edition which uses PAE.

Device manager reports "The device is working properly", supposedly. Only it
cannot detect any networks.

I think it's a driver fault with Vista and Windows 7. When I use 2003 on the
same hardware it's ok to 4GB.

Technically there is only an XP driver supplied, but it works also perfectly
on Vista =< 2GB, which is infuriating.
2G is fine. If I put even 2.5GB of RAM, no good. There must be a way to fool
it to thinking the system has less.

By the usually definition, most Windows 32 bit version appear to use
3.25 to 3.5 GB of the 4.0 GB RAM. It appear to be a physical limit in
the 32 bit. One of the reason why there were very few Windows Pro 32
bit based computers sold at stores.
