If you’re like me you have computers smartphones, digital assistants, smart TVs, and even alarm systems connected to the internet with Wi-Fi. That’s a lot of exposure if your home network can be hacked.

I’m going to show you some things that you must do to make sure you’re safe as possible. The device that creates your home Wi-Fi is called a router. It’s also called a hotspot or an access point It’s a box that looks like one of these or something in between. There are dozens of different manufacturers and they all look somewhat different but they all do the same basic thing: They take an Internet signal that comes into your house over a wire or cable and turn it into a radio signal that lets you connect all kinds of devices without wires.

The problem is your signal is in the air everywhere including outside your walls this gives hackers a possible way to get into your network. Here are my top six tips for making sure you aren’t the easiest person on your block to hack Number one: make sure your security is set to WPA2 WPA2 stands for Wi-Fi Protected Access version two and it replaced old security protocols WEP and WPA.

So select WPA2, not WEP, mixed-mode or just WPA, only WPA2. If you have an old router and it doesn’t offer WPA2, get in your car and go get a new router Only WPA2 is anything close to actual security. Number two: set new names and passwords that only you know. Change the names and passwords from the factory default settings.

When you choose a name for your Wi-Fi, don’t use a name that identifies the brand of your router or you personally. Don’t use your name or your address in your Wi-Fi name. Number three: turn off WPS WPS is short for Wi-Fi Protected Setup. It’s the button on a router that you can push to connect a device without having to type in a password.

Unfortunately WPS is vulnerable to attacks using free software easily available on the Internet. Unless you happen to just use it a lot and can’t live without the convenience, turn it off or lock it. Number four: use the guest network feature on your router. Many Wi-Fi routers come with a guest network option. Letting a friend or visitor who is in your home log onto your network as a guest gives them access to the internet without giving them access to your router’s controls and settings, and without access to other computers and devices you may have on your network.

It’s a secure way to share but not share too much. Number five: restrict access to your router. If someone can physically get to your router they are more likely to be able to connect to it and to hack it, or they can just reset it. Either way it’s best not to have your router in a location where just anyone can put their paws on it. And finally number six: keep your connected devices up to date.

Your network security is only as good as the weakest link so keep your devices and computers updated and keep your antivirus software up-to-date.
