Firstly to copy form a command prompt right click on the title bar of the dos window and from the drop down menu choose Edit and Mark. Then you can drag your mouse over the text in the window to select it. Once you have the text you want selected you press Enter and this puts the text in the clip board. I think it will loose any formatting when you paste it here but hopefully we can still read it. If you plug an ethernet cable from your laptop to your router does it work ok? If not you probably have a DHCP problem. If it works with the cable connected then you have a problem with your wireless connection.
Please open up a command prompt. Click on start -> run and type cmd Type the follwoing command and press enter. (Without quotes) "ipconfig /all > c:\output.txt" This will create a file at the top of your c: drive named output.txt with the current tcp/ip configuration of your network card(s). Copy the contents of this file and paste it here and we may be able to see a problem. It sounds to me like you have a DHCP problem but the output will tell us more.
