D-Link DWL-G650+ hangs my laptop

Hi!

I have a D-Link DWL-G650+ PCMCIA card in my laptop. The card works
fine, but when I unplug the power cord and start using the machine
with battery power, it hang if I transfer any larger files or have
constant traffic going on. After testing this problem, I have come
to the conclusion, that the cause is the D-Link card. Has anyone
else experienced this kind of behavior with wireless D-Link cards
and is there any way to fix the situation? I already have asked
the D-Link tech support about this, but they couldn't come up with
any usable solution.

The laptop is running a Windows XP Home Edition (SP1) and the
network card drivers are the newest ones available. The laptop
is an HP Pavilion with Athlon-XP processor, which has some quite
heavy power saving functionality, when running with the battery
(could cause problems?).

Hi Matti,

I really don't know, but I can imagine, you could have asked the right
question. Maybe you should try to turn off powersaving for the card. I
think u know how to manage this

Hope this will fix the problem.

regards,

Jens

PS: I dont think this is solving problems, but maybe u should try to
install sp2. Maybe you could check, if there are differences using
windows or knoppix (bootable linux by cd - www.knoppix.org)

I checked and it seems that the card is in "continuous access" mode.
In other words, the power saving mode is off.

Well, I was reluctant to try the SP2, because I have had some problems
with it in the past. But I installed it anyway and still the problem
exists.

I also tested the card with Knoppix 2.6 and ndiswrapper. Unfortunately,
the ndiswrapper didn't get the Windows driver working.

There are 4 mutations of the G650 sold in the US plus the G650+ which
is NOT sold in the US. Which one do you have and where?

Linux drivers appear to be available from Realtek.

Well, I'm the one who is in a need of the Linux driver and I'm living
in Europe and using G650+ card.

Thanks for the link. I'll need to check the acx100.sourceforge.net
project...

OK. I was able to fix this problem. I changed the Wlan card to use 11b
instead of 11g connection. This seems to prevent the hanging.

Does anyone else has experiences of this kind of behavior where
forcing the card to use 11b will fix connection problems?

Well not rearly,

Do you have the newest driver installed from dlink website?
If this doesnt work try the atheros 3.x.x driver.

I use this here because it supports althoug passive mode for capturing .)

If you dont know where to get it,feel free to email me.


Regards,
Ingo

Yes, I have. I also noticed that when the laptop battery is almost
out of juice, the computer may hang under heavy traffic even if the
card if forced to work as an 11b card. So, now I'm suspecting that
my laptop can't keep up the stable power at the PCMCIA slot.

Interesting. What does Ahteros have to do with D-Link cards?
I thought that the G650+ uses Motorola or TI chipsets.

Well i havent looked at the chipset yet.
I always use www.wildpackets.com website for lookinf for hardware
Go to the support page and look under airopeek supported hardware v2.x
If your card is in there it deffently can do passiv mode
You althoug will find a link to the atheros driver there.
Pls use only the driver they announce on their website.i tryed newer drivers
form them and they didnt fitt.

Was the same with dlink 610. As they write on their website the realtek
driver should work,but it didnt.

I patched the driver and voila passiv mode worked.

Seems the best built database on their website about cards and even normal
pci cards that can handle other drivers.

Cheers,
Ingo
