Ever thought about that someone in your next door might have hacking into your wi-fi router and using your connection for free? Worse is when you find out you are too slow even opening up web pages just because this guy is downloading huge media files from P2P networks day in and day out.
Fortunately to protect your wi-fi router from someone hacking into it is fairly easy.
First, you need to get onto you wireless router's administrative interface.
Once connected to your wi-fi, normally you can type in http://192.168.1.1 in your browser's address bar. If no page shows up at all, you may look at the user manual from you router to find the IP address and the username and password for it.
Here are some default login for popular routers:
I strongly suggest you change the default password for your administrator account on your router to keep it safe!
After you successfully login to the administration interface.
Find the wireless section in your admin interface, change the settings in the following steps to make sure your router is rock solid. You won't need to do all of them, but #2 is recommended to be done at least.
- Hide SSID, so people won't even see and connect to your wi-fi hotspot unless them know the SSID. (Typically under default page)
- Use WPA protocol plus AES for encryption instead of using WEP and TKIP. This proves to be the best way to prevent wi-fi from hacking. (Typically under security page)
- Select a password mixed with both numbers and characters and at least 8 digits long. A combination like this will reduce the chance that hackers may use brutal force to guess out the password. (under security page)
- Enable MAC address filtering and input the MAC addresses of only the computers that you'd like them to have access to this wi-fi router. (typically found on advanced page)
- Close your wireless router when you are leaving home. Saves energy by doing this and as a side effect, no one is ever hacking into your wi-fi when it's off. :)
