Get the wi-fire. I have it, though I’m not using it now.
It triples the signal, approximately.
It costs...about $55 —all kinds of people will ask you about it.
You can also boost the signal further by using a common colander or strainer behind it —buy one at a dollar store.
You can also make a CANTENNA quite easily. It’s loads of fun.
Here are some possibilities.

It may be illegal in your state to use someone else’s signal. Do some research on your state.
This one is HILARIOUS, and I’ve done it —it works.
ALL KINDS of people will love this, and will stop to ask you about it —the MacGuyvor factor is SUPER high with this one —they will look at you like you’re ET, phoning home.
Mount it on top of a camera tripod, and it’s a total scream. And really cheap. I love this stuff.
