Losing Wireless Connectivity with Intel Pro/Wireless 3945ABG adaptor

I am using a Compaq nx7400 with an Intel Pro/wireless 3945ABG adaptor, I have loaded the latest driver and software from Intels site. When I access my home network, via wireless, I connect for about 3 minutes then I lose connection and get the message 'Another wireless LAN utility is communicating with the Intel PRO/Wireless LAN adaptor. To avoid conflicts Intel profile management features have been temporarily disabled.' I can reconnect by switching back to the Intel adaptor, but after 3 minutes it loses connection again.
I am using XP Professional, and I have removed and re-installed the adaptors and the drivers but still get the same problem, how do I find where the conflict is coming from?

- Right click on Network Connection and select properties.
- In Wireless Network Connection properties, click on Wireless network Tab and verify the box "Use windows to configure my wireless network settings" is clear or unchecked.
- Double click on Intel ProSet on desktop icon or tray, if you have already the profile, then click on network Tab, the profile should display available network for you to connect to.

Try that see if it helps.

Hi Punky, unfortunately when I right  click on Network Connection, there isn't a Wireless Network Tab, only a General and Advanced. If I select the IntelPro icon I can connect, but again ony for about 3 minutes before it loses it stating that another wireless LAN utility is communicating with the IntelPRO adaptor

You can stop the INtell Proset from starting in msconfig startup . . it seems to be fighting the windows wireless configuration

What happens if you uninstall the Intel proset  . . you will probably have to restart the Zero Config service . .

Just like before. It connects for a while then looses it - still says another program is managing the connection!!!! When I tried restarting zero config service it comes back with 'The wireless Zero configuration service on local computer started and then stopped. Some service stoop automatically if they hav no work to do...'.

HI Punky! Sorry not getting back before, just having my tea! By turn off power saving do you mean in device manager/power management? if so, yes both the broadcom and PRO/Wireless are set to allow the computer to turn off to save power. If not there where do you mean please?

...if so, yes both the broadcom and PRO/Wireless are set to allow the computer to turn off to save power... You are right there :) try that.

Also, you said "broadcom" , is that other wireless device?

Sorry, you should also have to check in device manager > network adapters > Intelproset > properties > Advance > Power Save Mode > OFF as well.

You have already tried WZC, IntelProset, and couple of possible ways to resolve issue, but it is still. Does that card ever work good before? If so, do a system restore to sometime you know it worked?

Do you have system recovery cd?

Then, I suggest you get other wireless cardbus to try see if the Intel ProSet is faulty. This is not really good comment, but you have done most of possible ways to resolve and still not get it working.

Hi Punky! I am pleased to say that my problem has been resolved. I went onto HP support and they found me 'new' versions of the software and driver. But just for you info, I ended up with two entries my services for wzc 1. wireless zero configuration and 2. wireless zero configurator. Now, I don't know at what point the second one was added but after, that I was able to use windows to configure the connection and all was well.  Thank you so much for all your help.
