Contact your IP and monitor your internet usage, if it goes up during periods you'r asleep, out of the house or otherwise not using the internet, you know somethings up.

Setup a password on your WiFi and dont tell anyone.

Just find your router IP and login to your router. There should be a log and you can tell what computer logged into the router at what time.

You could also restrict access through mac address if you want. This would only allow registered computers onto your router.

Do you even need wifi? Just turn if off if you don't. As thor said restrict wifi access to approved mac addresses. Change the password, make it hard. Some also allow you to turn the power down. Only use as much power as you need for your devices. And of course turn off SSID.

try a trial version of this software

tells you who is connected and tells you when some one new joins your network

mac address filtering and turning off your ssid wont stop some one who knows what they are doing

True, but no SSID, encryption and mac address filtering should provide a big enough pain to whoever that they wouldn't want to hack in.

depends how badly they want to

as mentioned the safest thing is to turn off wifi altogether

problem is wifi is convenient

but personally i run 20m ethernet cables from the router

the problem is the average user is clueless when it comes to wifi

ask most people about their wireless security and they dont have a clue

most leave the default log in details to their router

wep security is pointless

and even wpa isnt what it could be with gpu accelerated cracking

also some wireless routers have faults as well

a well known uk company shipped a load of routers where they used the mac address to calculate the default password

unfortunately if you must use wifi you need to be paranoid about it :(

if u monitor unusual traffic like u r using only 500mb & data usage is 700mb.., u get lower browsing/downloading speeds..
you'd setup a password.

Some other ideas (once you decide to play with them):
Change the name of your Wifi to FBI Surveillance Van
If it’s a managed router, change all your computers IP’s to static, and make them an illegal sequence, that way no one can see them from the outside of your lan.
Don’t use your wifi for a while and autoforward all IP requests to some nasty Russian porn site. That’ll make sure anyone using it won’t have a functional computer for long.

I am not being serious, although all of them are possible.
