Pci wifi card dlink dwl g510 rev.c2 won't run on win7.

Computer: Windows 7 (64bit) desk top.
OS: windows 7 hp 32bit.

Tried to install this wifi card:
Pci wifi card d link dwl g510 rev. c2 firmware 5.00 device id: ven 1814 dev 0302

Used this d link win 7 driver:
DWL-G510 Driver/Utility 5.30EUs0038 for hardware version Cx only
-Windows XP 32/64 bit
-Windows Vista 32/64 bit
-Windows 7 32/64/bit
Please see enclosed release notes for release information...

The card in fact connects to the router. Signal strength poor.
And gets access to the internet. But speed much lower than another win 7 computer (same distance and also mostly stating connection strength poor)
also connected to the router.
Within minuts the transferspeed decreases and within 5-10 minuts in reality is 0.
The card will often disconnect, and reconnection to the router demands a reinstallation of the card,
if possible at all.

Can the problem be solved?

The scenario described above I have also experienced with several usb wifi dongles, new and used ones.

Is the d link wifi card's chipset a ralink rt65 and is that the same as rt2500?
Or more specific: Which of this drivers, if any, should I try:

see what happens when you set your router to use Wireless G only

Thanks for your answer.
I changed the router settings to g only. There is a checkbox named Enable "802.11g+ mode" too.
Should I check that box?

Changing the router settings to g only made no difference.
At this point the d link wifi card won't connect at all.

I anticipated that, therfore I'm running these installation excercises on a 2. hard drive.

Maybe I should mention that I have also tried 4 different usb wifi dongles. New and used ones.
Some came with win 7 drivers. Always the same result.
Some have said the router is the problem, it's a pre win7 router.
But why does the notebook (running win7) then connect to the router, and being fast and almost stable?

I tried to use an usb 802.11n wifi dongle (tried it before without succes), and I noticed
that when dowloading, the wifi "status" window said "connection speed 18mbs (or even 11mbs)"
all the time, while the notebook's wifi status window says 54mbs almost all the time.

Can it be that the desk top wifi cards simply can't manage the same distance as the
notebook? Maybe I should move the desk top for testing purposes.

It turns out it is a distance problem.
If the wifi card gets closer to the router
the card runs stable and fast.
I will try a bigger antenna, but I don't know whether it will work.

I tried a much bigger omni antenna.
Made no difference.
Anyone who can recommend a strong usb wifi adapter?

If you have a PCIe 1x slot available try this card
