Yet ANOTHER computer problem, HELP!

I cannot stand this computer. Well I recieved and xbox 360 and tried to connect it to the internet via the laptop. Didn’t work, but now the laptop will not connect to my home network, a few times it gave me a “conflicting IP address” error but i tried changing the IP manually with no avail. I keep having to disable and enable the network connections because it stops reading wifi networks after about a minute. THis is so annoying, I can’t restore because I was stupid and limited the space system restore can take up when i first bought the computer. This is a serious problem as I have no internet right now! Please help.
