D-Link DWL1000AP & DWL-650 disconnection on heavy use
Ken Hashim
I am using a D-Link DWL-1000AP access point and 2 DWL-650 PCMCIA
cards in notebooks for my setup. Notebooks are running Windows 2000.
The AP is connected using a crossover ethernet cable to a Windows NT
desktop PC running NAT software to allow me to share my dial-up
connection. DHCP is not used and all the PCs have manually assigned
IPs, gateways and DNS where appropriate. Signal and link quality is
around 90% with no network traffic. I can ping all the PCs in the
network, share files and folders and surf the web.
However, when using the notebook PCs, I notice that whenever I
strain the wireless network, like for example transferring a large
file from one PC to another or playing a Quicktime movie over the
network, my link quality periodically degrades to below 20% and often
disconnects and reconnects.
I have upgraded the firmware for the AP to 3.2.31 and I am using
the latest driver for the notebooks ver 1.07.18 (but the d-link
website download link says 1.4; weird!). I am using Channel 6,
Infrastructure mode, and I have assigned my own SSID for all wireless
devices. Tx rate is set to "Fully Automatic", but setting to lower
settings does not solve the network degradation/disconnection
problems. PS Mode is off on the clients. No WEP is used. MAC exclusion
list is not used i.e. open to all clients. HighRate on AP is unchecked
(toggling this does not make a difference with my problem).
Anyone else noticed or have this problem? How can I have a stable
wireless network with my setup? I appreciate any help.
p.s. By the way, I had originally bought the DWL-650 cards first
before getting the DWL-1000AP and had the cards in adhoc peer-to-peer
mode. This setup did not exhibit the degradation or disconnections as
mentioned above.

I have also problems with winXP and Dwl 650. I have a
network with two W2K machine, one win98 and two XP. The
non XP machines can communicate and access Internet
without problems. When I start one of the two XP machines,
it takes about 3 minutes, then is the communication lost
for all machine, and the D-Link router lamp is indicating
service. Something wrong with TCP/IP in XP????

Problem solved!! After a few hours of reading through recent postings
in newsgroups, I read somewhere that someone had used an Intersil
Prism II driver with their PCMCIA cards. Intersil, for those who don't
know, make the chipset in the D-Link DWL-650 cards. This led me to
find the driver at this page:
http://www.intersil.com/design/prism/ss/p2smtrx.asp
The driver is the Production Driver Package Executable
ISL3PRDSUIT-EXE. Click the link on the right side of the page. I
uninstalled all previous D-Link drivers and installed the Intersil
ones. It installed version 1.07.29 of the Prism driver (a few minor
versions higher than the one on the D-Link website it seems) and a new
Config Utility (with a Prism logo). I have checked that this Config
Utility also runs in Win98 and higher including my brother's WinXP
desktop! The end result is a rock steady connection and even signal
strength and range seem to have improved! No more disconnections and
file transfers and playing of large Quicktime movies are fast with no
jerks and stops. Woohoo!
In a nutshell, uninstall the crappy D-Link drivers, install the
Intersil Prism drivers and you will be in wireless heaven!
