Question about D-Link Air DWL 520 802.11b (DWL-520) Wireless Adapter

D-Link Air DWL 520 802.11b Wireless Adapter problem

I updraded my D-Link dir-625 wireless router to V3.06 and now my wireless adapeter on another computer won't connect or even detect the signal. I have two laptops that connect OK. I've reloaded the adapter driver, tried uninstalling it, disabled and enabled it, changed just about every setting I could and even did a system restore on the affected computer to see if that could be the problem. I've taken all the security off the router (I live in the country with nothing nearby to pirate a signal).The little green light on the adapter flashes a few times if I reboot the computer but that's it. The ipconfig show the ethernet connection is not connected as well as the wireless. I'm at a loss except to buy another usb wireless card.

    Oh, it's not a USB card I'm using, my D-Link Air DWL 520 802.11b Wireless Adapter is mounted. I can try taking it out and reinstalling it.

    It actually saw the network but when I tried to connect, it started to connect then stopped and now it doesn't find any networks again. Very odd.

  • allan_walsh Nov 19, 2008

    I've tried changing the channels, no luck, Also I had "Excellent" signal strength before losing the signal.

  • allan_walsh Nov 20, 2008

    The signal strength was "excellent" before it tried to connect. The computer is close to the router.

    I looked at the log onthe router and about the time I tried to connect it showed:

    Wireless system with MAC address 001195E4BDE3 disconnected for reason: Received Deauthentication.

    That`s right, took off all protection. Firmware upgrade.

On the computer with the USB wireless card. Uninstall the wireless adapter program and use only the driver so that you can connect with the Windows wireless configuration utility. Then restart the computer and see if you are able to see the signal now. if not create a profile put in the SSID of your network and connect

    Same difference it will not matter. Uninstall the program then just install the driver.

    Uninstall the program then restart the computer put the CD in the drive then if the installation for the CD comes up cancel it. The found new hardware wizard should come up. Choose the No not this time then install autoamtically after that a small single computer icon should come up in the lower right corner of your screen right click then click on view available wireless networks then see if you can see a network now.

    How far is the router from that computer. Make sure that the adapter antenna is screwed on securely next thing try chaging the channel on the router to 1 or 11. Also try lowering the beacon interval to 50 and fragmentation threshold to 2304 also try to point the antenna towards the router.



    That will isolate if the problem is a low signal strength. Try as well to wrap the antenna in aluminum foil to boost its receiving even just a bit.

    I would assume that you have completely no security on the router any longer. By the way when you said initially tha tyou upgraded the router was it a hardware upgrade or a firmware upgrade?

  • Thomas Lim
    Thomas Lim Nov 20, 2008

    Just a question did you do a hard reset after the upgrade of the firmware? Most router manufacturers require a hard reset after a firmware upgrade Before the unit will work as normal? Ive experienced that a lot with Netgear and Linksys routers so i would imagine it to be the same.



    Lastly make sure that the computer is atleast more than 5 feet Away from the router as signals will bounce.

I don't know how to set a password on my d-link router because my internet is insecure. How do i do this? I have the default username and password, but i don't know what to do from there.


1.Open your Internet browser and type in the default IP address for your DIR-625 wireless router: 192.168.0.1. A window will appear asking for your DIR-625 wireless router network name and password. If you do not know your existing network name, enter the default network name, "Admin." Leave the password blank. If you have already set up a network name and password, enter it now. Select "Log In."

2.Select "Wireless Settings" from the left-hand navigation bar. Put a check mark in the box marked "Enable Wireless."

3.Type your new wireless network name for your DIR-625 in the box labeled "Wireless Network Name."

4.Type your new password for your DIR-635 in the box labeled "Pre-Shared Key."

5.Select "Save Settings" from the top of the screen to save your new password.

Set you router to WPA security:
For this DIR-625 router if the encryption is set to WEP it could only give up to 54mbps wireless connection. If it is set to WPA it can give up more than 100mbps wireless connection, but it depends if the wireless adapter in the computer is also a Draft N adapter. Its a backward compatibility.

The WPA key is the encryption key that is configured in the router's wireless settings and the wireless cards in the laptop and desktop needs to be configured with this encryption setting to allow the laptop and desktop computer to communicate with the router.
You can view the encryption settings in the router's wireless settings or on the laptop's wireless card settings and then apply these encryption settings to the desktop's wireless card (ie. the SSID and the WPA encryption).

Check your settings on your wireless setup and make sure the adapter on your computer is set to Security Type: Shared. That is the most over-looked stumbling block.

Use with dwl-2100ap


What you need to do is configure the dwl-2100AP. You need to login into the repeater's configuration page and go to Home tab, click on wireless on the left. Select AP Repeater under Mode. A new screen will show up. Click on the scan button to see if your router's signal is being picked up in the box. Just select the signal if you see it in the box and put in your security info if you have one.

D-Link Wireless Router DIR-625 unable to connect with D-Link DWA-130 adapter


Sometimes the security settings will only let certain MAC addresses connect to the network as well as the password protection. Make certain that yours isn't filtering out MAC addresses.
