Question : New Dell Inspiron 1150 does not connect to wireless network

I have a New Dell Inspiron 1150 and it will not connect to my wireless network.  I have 3 other notebooks that connect to the wireless net just fine.  This machine was working last week with it but now I get an error saying "Windows is unable to connect to the selected network.  The network may no longer be in range.  Please refresh the list of available network, and try to connect again."  I do a refresh but get the same thing?

I am using windows XP home.  I have disabled any TSR's from memory.  I have tried removing and reinstalling the wireless device from the OS.  

Thanks

Answer : New Dell Inspiron 1150 does not connect to wireless network

Can’t connect to a Wireless AP (Access Point) or Router

First open “My Network Places” (or network neighborhood if your 9X or ME) for XP users this will be on the start menu or desktop.

Click “View Network Connections”, you should see your wireless network card, right click it and select properties. Select the “Wireless Networks” tab, and press the configure button.

In the SSID box type the SSID for the device you are trying to connect to (they are CaSe SenSiTiVe)

You should now be able to connect if not do the following, try each step one by one and test connection after each one.

1. First make sure this isn’t the problem
Wi-Fi Protected Access (WPA) Patch (Q815485) Can Cause Connection Loss

2. Click start >Run >services.msc {enter} locate the “Wireless Zero Configuration” Service, right click it select “Stop”. Right click it again select properties and change its startup type to disabled.

3. Go back to My network places and bring back the properties of the wireless network card (as described above) on the “Wireless Networks” Tab click Advanced > Power Management > un-tick the default tick box and move the slider all the way up.

4. If non of these has worked, then I would suggest getting out the CD that came with the Wireless card and looking for a setup utility on the CD. If you have cordless phones in the house unplug them.

5. If your still drawing a blank, then I’d suggest “borrowing” a laptop with Wireless to see if it can see your AP/Router and to see if anyone else has one running near you that is interfering with your signal, http://www.netstumbler.com/ is a good utility to see what's broadcasting around you BUT it will not detect networks that have a hidden (not broadcasted SSID) you need something expensive like http://www.airmagnet.com/ for that. Remember wireless runs over numbered channels if you pick up another network within TWO channels of yours it will interfere.

If your locked onto another network see
