Problems with your wireless computer shutting down or losing your home network?

The issue could be Windows Zero Configuration. It is the generic Windows system used to manage wireless networks and is a good tool to have in a laptop that you take out of the house. It is not needed on fixed location computers such as home/office desktops.
You do not need a system that searches for a stronger signal to be searching and switching (sometimes to a protected network that does not allow access) when you want to be on a specified network.
The key here is GENERIC. If your wireless device manufacturer has utilities and drivers to run their devices, good chance that software is more specific and will work better. Sooooo

Here is how to shut down Windows Zero Configuration if you are having those wireless connectivity issues and have to continually run the wireless repair tool to get back on line or have to re-boot to get back on line on your fixed location computer.
It will do NO HARM to your computer nor to your network and this fix has been verified by many people. (a search on line for "windows zero configuration" will yield page after page after page of forums and reports and many solutions advanced) .. this one I got from a local repair shop several years ago, and has worked for me. ..... but make sure you have the latest driver installed for your wireless access devices from the manufacturer before you go ahead. If your device does not have SPECIFIC drivers and a CONNECT UTILITY, this will NOT work and you are stuck using the Windows wireless management then.

Start>
Settings>
Control Panel>
Adminstrative Tools>
Services>
scroll down to Windows Zero Configuration and highlight> (right click) Properties>
Start up type button and select window and set at DISABLE>
(if the service status buttons are enabled .. click the stop button .. otherwise ignore)
Apply>
OK>
Exit back out to your desktop>
Re-Boot

This will stop Windows from searching for another stronger connection, which is the reason behind the disconnects in the first place.

If this fails, you can always go back and turn the Windows system back on by following the same pathway.

Since this requires no monitary outlay for repeaters/access points/antennas/new card/new router .. and does not require moving furniture, it is worth a try.---------

NOTE: IF you have to run a restore on your computer or run SFC to repair files, you will have to do this again.
Also, this fix is for Windows XP ONLY. There is a fix for Vista, but you will have to look that up for yourself!
