First thing you need to do is change the default username and password. Base for every wireless network is an access point or router. Manufacturers of these devices publish the instructions for proper setup on their websites, and it is not hard at all to go through this process. These web tools are protected by login screen so only real user can to this. However, to log in to any of these devices is really simple and hackers are really familiar with this, that’s why you need to make these changes immediately.
Turn on compatible WPA/WEP encryption. Technology of encryption makes the messages that go over Wi-Fi unreadable to people. There are several technologies for wireless encryption and, of course, it would be best to use the strongest method of encryption. Keep in mind that encryption technologies require all Wi-Fi devices to use the same setup.
You might want to change the default SSID or network name also. First thing someone needs to get into your network is SSID, but that’s only beginning. When someone finds out that your default SSID is not changed, they know that your network is weakly configured- networks like this are targets of attacks more often. It would be even better if you deactivate it completely. SSID has some use when it comes to business hotspots because their clients are often out of network reach, but if you’re configuring home network, SSID has no real use and keeping it activated increases your risk of intrusion.
After you did all this, you should activate firewall on every computer or router. Modern wireless routers allow you to use implemented firewall, but they also let you deactivate it. You need to check if firewall on your router is on, and for even better protection, you should use your own firewall on every computer you have.
You should position your router in a safe spot. It is normal that some wireless signal reaches out of your home and that it not the problem. If your signal reaches far away from your home, it is simpler for an unknown person to find it and use it. Position of an access point or router determines its reach. Try to position your device as close to center of a house as possible, that’s going to reduce your signal reach.
As the last security measure you should turn off your wireless network if you don’t use it for long periods of time, that will stop any hacker attack. Even though it might not seem like a practical solution, you should consider it if you’re out of your home for a couple of days. If you only use Ethernet connection, make sure you turned your wireless connection off.
