Its time for MAC address filtering to be enabled on your modem/router WiFi access - this will limit access to only your devices.

If you get a new device you'll have to add it on to the list of allowed MAC addresses

You'll need to lookup all the MAC addresses of your WiFi Devices
Or copy them off the modems status page of connected device before you enable MAC filtering

And a change of both admin username and password (on the modem) wouldnt go astray as well as changing the broadcast name of your modem

Might even be a good idea to remap the IP address of your modem so it cant be found by the same person and if you want to go a step further turn off SSID broadcasting so your modem isnt broadcasting its presence to all and sundry - but you will need to record its name and address !
You can always go back to default settings most have a switch or little hole with a press button switch inside the case that you use to reste it back to default if you need.
