Re: Malfunctioning wireless network adapter (Intel Wireless WiFi Link 4965AG)

I have similar experience too, but malfunction only happens when I am trying to connect to my school network which is WPA2-enterprise or WPA-enterprise. My wireless seems to work fine at home with WPA-personal. All other laptops work fine (so it is my laptop). The signal is fine because it register 100% strength.

 

Basically, mine works for a few minutes, then it starts malfunctioning (school network only). During malfunction, it cannot detect any wireless network (even those that aren't WPA-enterprise). When it can detect wireless network again, it may or may not be able to reconnect to the school network.

Uninstall ThinkVantage connection Manager, aside from the ability to store connection profiles it is just redundant and meddlesome.

 

then, with services.msc, configure the properties of your Zero Wireless service and set the advanced properties to play a particular sound or estanciate a popup shell ( your hardware description insinuates existing knowledge of how) to generate some type of consipciuos event in case the WZCSVC is dying for any reason.

 

If it still fails, then ensure the BIOS settings are set to MAX Performance everywhere possible and disable any power saving features and battery extender.

 

Still fails, boot hte system from a KNOPPIX CD to determine if the issue remains, if the internittent power drops occur when using a completely different OS then it is certainly a hardware issue.

Re: Malfunctioning wireless network adapter (Intel Wireless WiFi Link 4965AG)

Many thanks. A few questions re: the above suggestions, please.

 

  1. Is it necessary to uninstall ThinkVantage Access Connections in order to run Zero Wireless? Can the program not be disabled temporarily?
  2. Zero Wireless is a more robust utility or offers better diagnostic tools than ThinkVantage Access Connections, is that the idea?
  3. Could a simple compatibility issue with the authentication technology be causing an unstable wireless connection and other symptoms, as suggested in the earlier reply--in which case the answer could be as easy as switching to WPA or static WEP encryption? 

 

Thanks again. My understanding of some of the recommended procedures is insufficient for me to attempt them without a lot of anguish, unfortunately. A little more color would help me to decide whether I should have another go at this or bring the ThinkPad down to the service center while still under warranty (and avoid screwing things up myself).

I have an T 61 with O.S. Win7 64 bit, it works but I can't get logged in at Live Messenger ( while with mail IN from hotmail open, I have Messenger ) but the programm itself won't work! Via Microsoft forum I got the advice to update my driver; I tried it with the Intel Assistent programm, but afterwards I didn't have WiFi connection at all! Who can help me?

Hello,

 

This is probably an unrelated issue to the original poster's. 

 

Do you have any security software installed that might be interfering with Windows Live Messenger's ability to register with Microsoft's servers?   If so, try disabling it temporarily to see if that solves the problem.

 

Regards,
