|Is the router wireless capable?|
If not, then no, you can't.
If it is, then configure a Wireless network using WPA encryption and a complex password. Once you have the WLAN configured, connect to that WLAN (by it's SSID) from the laptop and login.
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.
