Typically the best way to do this is to enable encryption on your wireless network. What kind of wireless router are you using? If you can get me the model number I can point you to the directions on how to do that.

If you have your router's manual (Joshua helps you get it), set an administrative password, set a user password and select an encryption.

I like MAC filtering with white list.  Would-be thieves can't figure out why they can't connect to an apparent open router.

Craig, one small warning about that. If you have an open WiFi network or you are using WEP (which is easily crack-able) you can pretty easily (for someone who knows how to use Wireshark) sniff the MAC address off the packet headers that are being sent over the air and then spoof the white-listed MAC address.

Without encryption enabled or with easily cracked encryption, your WiFi traffic can be easily monitored as well. WiFi is kind of like communicating via smoke signals, everyone in between can see what you are saying if you aren't using a good code-book to communicate :).

Additionally, any site that isn't fully encrypted of HTTPS is at risk of having its session hijacked and someone can impersonate you (do a Google search about Firesheep which was a simple Firefox plugin developed back around 2010 that allows you to look for open sessions to hijack on open WiFi networks. Most sites such as Facebook and Gmail have resolved these issues but some have not.

Finally, if you really want to go down the rabbit hole, watch the movie Citizenfour :).

I should follow that up with, if you live out in the sticks like me, there is no one around to sniff any packets; so it's kind of a moot point :)

If someone is smart enough to crack your encryption, they are probably smart enough to spoof a MAC. But, it's still another good obstacle to lay down.

Like Joshua, I live in the woods. If anyone gets close enough to get on my WiFi without my say-so, my dogs let me know. Between my dogs & my guns, they don't stay long enough to use my WiFi, or to do any damage. I turn it off when I'm not using it.

I live out in the sticks and one of my neighbors keeps pilfering my gigs thru my wifi. I am pretty sure of who it is and would like to be able to 100% prove it, prosecute, and permanently block this crap. Any advice?

Check your router's configuration utility, most provide information regarding which devices are connected (some log connections). To stop, change your router's administrative password (the one used to access the utility) to a strong one, ensure that remote administrative access is not enabled, change the wireless access password (sometimes called key) to a strong one and specify that WPA or preferably WPA2 encryption be used.

Specific details on how to do that can usually be found in your router's manual. Each one is a bit different but it generally all starts with browsing to 192.168.1.1 in your browser (but even that may vary by router type).

Check the range on your router. You know, the distance you can get a connection from the router itself. We have one that doesn't reach much further than our picnic table. There's not much chance anyone could use it without our knowledge.
They would almost "have" to be parked in our driveway close to our house, or, be right behind the house, in the woods. Either place, our dogs would tell us they were there. Our guns would make sure they don't come back.

As Old Labs has said, it is important to have a good WPA2 encryption set up in your router, plus using strong access codes to your router's administrative functions.

While you may think you can check the range of your router by using your phone or laptop, be aware that there are some very capable wireless range extenders on the market for as little as $100. I use on by Amped at my lake home that can pick up usable WiFi signals from neighbors 1/2 mile away, and that is with the stock antennas. With the upgrade to a high gain antenna, they make claims that it is possible to pick up a usable signal from a mile or more away.

Secure passwords in your router will keep the intruders out.
