Everyone has WIFI at their home nowadays. Using it, you can connect pretty much any device to the Internet, without using cables. But how secure is your WIFI network? Believe it or not, most people don’t really know how to secure their WIFI , and I can’t blame them for that. Configuring a router is not very easy, especially when you start messing with the advanced settings.
The first and most important thing is using a password. Millions of people around the world still don’t password protect their WIFI network. This is very dangerous since without password, anyone can connect to the network. Then, he can sniff information and steal your personal info ! By encrypting your WIFI with password, you avoid such problems.
There are different types of encryption you can use to secure your WIFI router. The most popular are : WEP, WPA, WPA-2. I persoanlly recommend using wpa-2 since it provides better security and much harder to break into. But it won’t help you if you choose an easy password as “123456789”. It is super important to choose a complex password that contains letters, numbers, symbols, upper case letters and more. If you think you won’t be able to remember such a long and complex password, just write it down on a piece of paper (and don’t lose it of course).
It is also very important to update your router firmware. Router manufactures like D-link release new versions of OS for routers on regular basis. Each new version is more secure than the previous one (in most cases). When a security hole is found, the company fixes it, but if you won’t update the router firmware – it won’t take effect. In the past, very serious security holes were found in many routers. I always recommend buying a router from a well known company that you can trust.
