Users with the DWL-G630 and other wireless LAN cards have experienced a blue-screen error message, "DRIVER_IRQL_NOT_LESS_OR_EQUAL" with a mention of the file ar5211.sys.
The following steps may solve this problem in versions of Windows XP:
In preparation for these steps: A. Download the latest version of the DWL-G630 drivers from support.dlink.com. B. Consider setting a Restore Point. For additional information about System Restore, click Start, click Help and Support, type system restore in the Search box, and then press ENTER.
1. Go to Add/Remove Software 2. Remove your G630 software 3. In Explorer, go to %windir%\system32\drivers and, if you see AR5211.sys, rename it to AR5211.old. (Note: it may have already been deleted by Step 2, above.). 4. Reboot your computer and log on 5. If Add/Remove Hardware wizard comes back up, choose Cancel 6. Install the latest DWL-G630 software that you downloaded earlier. 7. The software should install and your network card should now be enabled or detected. If it is, proceed normally. If it is not... 8. ...Click Start, Run, and run compmgmt.msc and open Device Manager ... click the name of your computer at the top of the tree, then click the icon to scan for new hardware
The files required to support Windows 98, Windows 98SE, or Windows Me are missing from your set of files. Fortunately, there is a workaround.
1. Go to ftp://ftp.dlink.de/dwl/dwl-g520/driver_software (the directory might refer to a different card than your own). 2. Look for DWL-g520_drv_revB_Ver.4.11_ALL_en_050407.zip (or later), and download that file to your hard disk. 3. Extract the files into a folder or directory using WINZIP or some other ZIP-compatible program. 4. Run SETUP from that folder or directory.

This prompt means that your wireless network is already configured with some form of security, and now you need to provide the matching key for it.
If the person who configured this network is available, you should ask to be provided the network key.
If you are the owner of the network, you should enter the configuration pages of your AP or router. Depending on the type of device and the security used, you may or may not be able to see the key. If you are not able to see it, then you can change the key to something you can remember. Be aware that such a change would affect everyone using the wireless network.
If you have a wireless router, these settings are usually found on the configuration pages of the router. Otherwise, your AP will have different pages. Your user manual will give you the steps to perform. If you do not have the manual any longer, visit the support web page for your device. There you often can find links to download the manual.
