13 digit code and that was supposed to be that!
Could be that code was a security key that the laptop wireless needs to know about. Highly recommended for wireless networking - keeps all but the most talented hackers out of your data packets as they fly through the air.
With the laptop on - try to connect to your router via the wireless. If you can connect, try:
clicking Start > Run and type CMD here.
Type ipconfig /release
wait for all zeros then type
ipconfig /renew
This can take up to 1 minute - wait to see if you can pull an address - if it starts with 192.168 you may be good - if it starts with 169 or you get and error - something is not kosher with either the laptop's networking settings (TCP/IP) or the routers DHCP settings - or you are not properly 'connected' to the wireless router.
You
could call the router help line and or laptop help folks (should be free) and prepare for a 30 minute (if you're lucky) to one hour long session with a lovely beverage nearby. Just don't let the router people muck around the laptop too much and also the reverse.
