Wireless not working
Run the network tests from within the 360 menus - looking especially at the result for network address translation (NAT). If this is either limited or fail, you will need to change your router for one which is compatible with xbox live. Try xbox.com to work out which routers are recommended.
As far as your router kicking him when you connected your pc, then you must have altered the access permissions of the router maybe by accident.
If all else fails, turn off the pc, router, modem and 360. Find the reset button on your router and press/hold this for at least five seconds. Turn on the modem, then the router. Let that settle for a minute, then connect and setup 360 and laptop.
