The introduction of WiFi was a revolution in the wired world of technology. However, every technology has a number of micro-flaws, and WiFi is no exception: wireless networking is prone to a lot of security issues.
There are plenty of reasons for you to power up the WiFi in your home and keep your neighbors or hackers from hijacking your WiFi network. Here’s how to secure your WiFi the easiest way:
Setting Up The Basics
Most people often use the WiFi with its default settings, which makes it prone to hacking. Most Wi-Fi equipment is shipped with security disabled and most access points, routers, and gateways are shipped with a default network name, username and password to make it easy to set up your network and make configuration as simple as possible. These default settings should be changed as soon as you set up your WiFi network.
192.168.0.1 is one of the most popular IP addresses for getting in router’s web-interface. However, if you have trouble accessing your router’s web-interface, you can find your router’s IP address in the WiFi’s manual.
Different WiFi devices have different interfaces, so the settings will vary; however, the Setup Wizard will guide you through all the important settings. Also, do not forget to update your router firmware to improve connectivity and keep your WiFi secure.
Keep Changing Your Password
Change the password, which controls the configuration settings of your access point/router/gateway, regularly to remove unwanted devices from your WiFi or to put the number of people with access back down to zero.
You need to do this through your router’s settings — either take out the manual or run a quick web search to find the instructions for your particular make and model.
Set a Limit
When you install a WiFi in your home, the signal is broadcast all over the surrounding area where neighbors or other strangers can log in to your network and take up your bandwidth. Limiting your WiFi signal prevents outsiders from accessing your WiFi.
How do you do that? You need to minimize the amount of wireless signal leaking from your home. Re-position your router’s antenna to limit wireless signal range and change the wireless transmit power to 75%.
Using VPN & Security Software
VPNs securely “tunnel” network traffic over an encrypted connection and protect your WiFi from the government’s prying eyes and from hackers always ready to steal your sensitive information using key re-installation attacks (KRACKs).
You should also double up on Firewalls. While you have a firewall on your computer, usually built in to Windows or Mac OS X, your router also has a firewall to protect your internal network against outside attacks. Turn it on as an extra layer of protection.
Turn Off WiFi
If you have your WiFi on all the time, it’s not that hard for your neighbors or hackers to access your network by cracking your wireless password. So, when you do not use your WiFi, you must turn it off.
