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?

All 32 bit versions of Windows will not use the full 4GB of RAM. It
will limit the RAM available to 3.25 to 3.5 GB.

As previously stated, bad RAM is likely.

Hi,

There is one "kind of" exception to that. Some of the "higher" versions
of 32-bit Windows 2003 Server (e.g., Enterprise and DataCenter, I
think) will recognize memory 4GB. I run Win2K3 Enterprise on my main
desktop for that reason.

I think that an individual app can't use 3GB, but I use this because
sometimes, when I am doing development, I run a bunch of virtual
machines, and they each take up physical memory (each 3GB), so this
allows me to run more guests simulataneously (I currently have 6GB in my
machine).

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.

Does the wireless driver start at all with 2 GB? ( do you see it in
device manager?)
Any relevant messages in the event log with 2 GB?
