5) Use scary names to discourage Wi-Fi theft: If your wireless network
has a name like C:\virus.exe, most people who might otherwise access
your network will not for the fear of getting their devices infected. You can
use your creativity to find more dangerous names for your wireless network.
6) See Connected Devices List: Almost every new router will have a page which displays the list of every device that is connected to the network. You should check this page at regular intervals to see that unknown devices are not leeching your network. When you see an unknown device, you can be certain that someone has breached your network. You can try AirSnare, a free utility which scans your network for unexpected MAC addresses and also looks into DHCP requests.
7) Turn off Guest networking: While most routers will have guest networking disabled by default, it always pays to see that you may not have accidentally enabled it. Guest networking allows others to access your network.
8) Enable MAC address based filtering: Media Access Control or MAC address identifies each device connected to your network. MAC address is an alphanumeric key separated by colons. Enabling MAC address based filtering allows only devices having particular MAC addresses to access your network. You need to enter the MAC address of every device you wish to allow to connect to your network on your router's settings page. This prevents unknown devices from connecting to your network even if they know your password. To find the MAC address of your computer, open command prompt and execute “ipconfig /all” without quotes.
While it may prevent inexperienced users from getting access to your network, experienced hackers and advanced users can use a wireless network analyzer like Nmap and then change the MAC address of his computer with another free tool MAC Shift.
9) Keep your firmware up to date: Router vendors regularly release firmware updates and post them on their websites. You should occasionally check the manufacturer's website to see if a new firmware update has been released. Newer routers will automatically inform you when new firmware is available.
10) Reduce wireless signal range: If you reduce the range of your wireless network, common sense tells that it will prevent hackers located at a distance from detecting your network. This has the advantage that if hackers do not know that a wireless network exists, they will not try to break into it. You can place your router at places which would block the Wi-Fi signals. While this technique is advantageous, a hacker keen on hacking into your network will just have to use a larger antenna to pick up your router's signals. Moreover, reducing the range of your wireless network might cause troubles for genuine users.
11) When not using your internet network, turn it off: This is self explanatory. If you are not using your network, turning it off saves you from giving extra time to hackers to try and hack into your wireless network. While it may be impractical to turn every device on your network off every time you are not using the network, it still is advisable to do so during extended periods of non use.
If you follow all these techniques, your Wi-Fi network will be a lot more protected and hackers will have a tough time breaking into it
