I am running a WIN2K Advanced Server hardwired to a D-Link DI-524 router. There are 8 PC's connected via D-Link DWL-G510 wireless cards. Each client is running WIN2K (SP4), except one which is running WINXP Pro (SP2).
Until yesterday, everything was working fine. We started experiencing random connectivity drops on all our wireless clients. I did the normal troubleshooting and found nothing to be wrong (hardware). After two hours of technical support "help" from D-Link, they determined that the router was defective, and should be returned for warranty replacement. I removed the router, and replaced it with an identical DI-524, fresh out of the box. I am still having random network drops. The wireless PCI cards are working properly.
After working on this for several hours, I found only one thing in common among these clients. The wireless connection is perfect, until the user opens Internet Explorer. As soon as the browser is opened, the wireless connection becomes unavailable. After the browser is closed, the connection restores and operates perfectly for intranet use as well as email. However, if you click an internal software link (i.e. Online Help in Adobe Acrobat to open a URL) I.E. works fine. I only lose connection when the I.E. icon is clicked and opened.
I have virus-scanned each client and found nothing. Can anyone tell me what is happening and why? Any help would be GREATLY appreciated...
Thank you...
