|WEP can be cracked in 10 or 15 minutes with the right tool. I highly recommend you first, redo your wireless network using WPA encryption. Change your password too and use a complex one.|
Then, find the place in your routers management interface where you can allow clients by their MAC address and specify all of your PC's and laptops. Once done, only those MAC's (and their associated devices) will be able to connect to your wireless network.
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.
