|Did you make any changes to the wirelss network while moving?|
Did you perhaps accidentally reset the router while moving it? (check the configuration).
If no to both questions above I would suggest you delete the existing wireless profile on your laptop and then I'd reconnenct to your WLAN.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
