Problem with D-Link DWL-AG660 Wifi card

I purchased a D-Link DWL-AG660 Wifi card and installed the drivers as per the instructions. When I boot my Win XP Pro ( SP2) laptop, the "AirXpert Configuration Utility" tries to launch and I get an "Entry Point Not Found" message. The subsequent error message indicates that a procedure entry could not be located in the dynamic link library athcfg10.dll . The card itself appears to be working as I can configure it using Windows XP, however the Airpro configuration utility is giving me this error. Any help offered would be much appreciated ! Mario

It seems you've reinstalled the device driver and some files have been conflicted. press ctrl+shift+esc it will open task manager select error task> right click it> go to process "note the process name" go to run>"msconfig" and disable the same process. it'll atleast prevent that utility to lunce. *otherwise, Uninstall the driver and software from add/remove program of controll panel, *delete all the related registry keys *install the device as per the manufacture instruction thanks Arun

Setup is unable to detect card however windows

You aren't very descriptive. Either way. I'm assuming when you say Setup, you are referring to the driver installation setup. Delete/uninstall the driver. Unplug the adapter. Now, start the setup. When the installation goes along, eventually it'll ask for you to insert the card, thats when you insert it. It should then work, if you finish the setup. If thats not the issue. Heres a possibility. You are running windows Vista, or running Windows Vista 64 bit, or maybe XP 64 bit. Either way, you are likely using a 32 bit driver, on a 64 bit machine. Or vise versa. If not then you could be using a vista driver on an XP machine and the XP machine doesn't know what to do with it. I suggest going to dlinks website. There are 3 versions of this wireless card, and that also could be the issue. The first one they released is here http://support.dlink.com/products/view.asp?productid=DWL-G630 and that only has drivers for XP and 2000. http://support.dlink.com/products/view.asp?productid=DWL-G630_revB rev B. Also only XP and 2000. http://support.dlink.com/products/view.asp?productid=DWL-G630_revC rev C. also again XP and 2000 BUT includes a Vista 32 bit driver. I hope i helped. Not bad for free...

I am not able to install driver for D-link wifi card

The card could be bad. I've found over the years that most of these desktop wireless cards work best when the software is installed before the card is installed. Meaning uninstall all the software. Turn off the machine. Remove the wireless card. Turn back on the machine. Install the software. Once installed, shut down the machine. Install the card. Turn back on the machine and lets Windows find the card and the software.

Why cant i connect my dlink

Forget the D-Link drivers!!! I suffered with this same DWL-G630 issue for two years, trying different settings, reloading drivers, all with no solution. My card kept dropping it's connection, or wouldn't connect at all until I removed then replaced the card. Finally, I read on another forum this card uses the same chipset as an ASUS card, and to try the ASUS drivers. I downloaded and manually installed the drivers from here:


Unzip it, but DON'T run the setup.exe file, because it will try to install the ASUS program. If you open the unzipped folder you will find another folder called "Drivers". Just use your Network Settings (from your Control Panels) to manually update the driver of your DLink card, and navigate to the Drivers folder just mentioned. Reboot -- you'll probably have to reconnect to your access point/router one last time, but that's it! It's good as gold after that.

I was used to losing connections 5-8 times PER DAY (I'm 15 feet from the router!) and now I've been connected non-stop for two weeks and counting!!

D-Link Airplus DWL-G520 problem with windows server 2003

D-Link Airplus DWL-G520 on PCI drivers do NOT support Server 2003. It will only support these OS

Windows 98/Me/2000/XP

If you boot your XP is it still working ?

Driver for d-link dwl 520 wireless PCI card for LINUX OS

please go to the following web site and download the Driver and Instructions--


No Card


After installing the wireless card into a PCI slot, when you booted the pc, did you get a New Hardware Found message? If not, try another PCI slot.

Basic Installation


You need to use the D-Link USB WiFi Utility and manually configure the WiFi Network. Sometimes the built-in Windows WiFi Configuration doesn't work well with some USB WiFi and/or when no WEP/WPA security installed.  You may need to manually enter the SSID, "Open" encryption and "Disabled or "Not USed" security settings.

Good luck and kind regards.
