Wireless on laptop connects and disconnects constantly

I have a Dell Inspiron E1505 laptop and at home on my AT&T Wireless Router the computer connects to the internet via the wireless just fine.    On any other wireless it connects, then disconnects and constantly connects and reconnects.  I removed the antivirus (avast), disabled the windows firewall and it continues to connect and disconnect constantly.  I run the windows troubleshooter but it tells me there is an error but provides no details.  Again, at home the wireless works fine on my AT&T Wireless Router.  Any ideas?  Thanks.

I did finally get this to work but I had to remove all the drivers that the DELL was installing for the wireless card and use ONLY the windows XP drivers that detected.  Once I was running with ONLY windows XP zero configuration settings would the network connection stay active.  Thanks for all the help.

I should mention I have tried to use both the broadcom wireless software and just windows to manage the adapter and I have checked that all the drivers and software are up to date.

set all properties of your network card to default, maybe you changed something which is ok for your local wn but not the others...

when having problem with wireless disconnects - try checking power settings
Device manager - WiFi card and uncheck "Allow computer to turn off this device ...)
if you have Vista/Win 7 look at power schemes as well - make sure that wireless is set to Maximum Performance in advanced power settings

At these other locations are you the only one connected?

Is there other activity going on there, like microwaves and|or cordless headsets/phones being used?

Are you running off the PA-12 (AC) adapter, or the 6400/E1505's battery?

Which wireless card do you have, exactly?

Have you tried turning off the bluetooth to see if that helps?

     Several other computers are connected - they all work fine, i tried disconnecting the other computers so mine is the only one connected but it still just cycles connect/disconnect.  I went to starbucks today with two laptops and the other one connected immediately and mine just connected and disconnected.

=Is there other activity going on there, like microwaves and|or cordless =headsets/phones being used?

no other wireless activity

=Are you running off the PA-12 (AC) adapter, or the 6400/E1505's battery?

=Which wireless card do you have, exactly?

I checked the power settings and made sure to disable any power saving items but it has not made any difference.

Could you give us a quick rundown on the process used to remove the driver and reinstall it, please?

Thanks.

Best thing is to buy USB wireless card , install it and see if you have same problem ( disable original form device manager)

wasting time is wasting money

problem still persists?

This happens on ALL other WiFi networks, other than the one you have at home?

You can mark that (http:#26304003) as the solution, then.

I was still waiting for an answer to my question in http:#26109972 before making more suggestions. It IS possible to load just the drivers from the package Dell supplies, without installing their 3rd party connection manager.
