I've said it before, but I'm going to say it again: Criminals love open home Wi-Fi networks.
They can attack your gadgets and steal your information; they can download - or upload - illegal files, and they can generally do whatever criminal activity they want. When law enforcement traces their activity, you - the router's owner - are left holding the bag.
Even if criminals don't target your Wi-Fi, what about your neighbors? They might be surfing the internet on your dime, and all you get out of it is slower internet speeds. Click here to find out if your neighbors are stealing your internet.
You really don't want either thing to happen. Fortunately, it's easy enough to keep people off your network. In fact, it only takes a few minutes.
I'll walk you through every step of the process to make sure you don't leave any hole open for someone to sneak through.
Note: These steps aren't just for setting up a new router, either. I encourage everyone to go through this process step by step to make sure your router is locked down.
