Thank you for the tips.
But I couldn't make it work.
So this is how I fixed the dealie.
I used duct tape to fix the problem.
1. I unhooked the airport.
2. I plugged the wire from the modem into my laptop.
3. I taped the cord that is now across my living room floor to the ground.
4. Now my internet works and no one else can use it.
Truly. That's what I did.
