I would love to be able to tell you how to prevent anyone from hacking your router, but there is no fool-proof method. In fact I scoured the internet in the vain hope of finding a definitive answer, but that search wasn’t altogether fruitless, as it unearthed an interesting post on netsecurity.about.com.
From that article, I have listed below 4 tips that will help you make your wireless router harder to hack and hopefully fend off any potential threats.
1. Enable WPA2 wireless encryption
Without WI-FI Protected Access (WPA2) encryption your wireless network is wide open to hackers. Even using outdated Wired Equivalent Privacy (WEP) security isn’t enough to keep them at bay. That’s why you should check your router manufacturer’s manual to find out how to enable WPA2 functionality now (a firmware upgrade may be needed for older routers).
Plus, it’s important to make a strong SSID (wireless network name) because using your default network name is easy to hack. Create something that’s long and random. Admittedly, that will make it hard to remember, but better that than giving the hackers easy access.
2. Turn on your wireless router’s firewall
Your router’s built-in firewall will help make your network less visible to hackers, It’s also best to test it to make sure you’ve configured it correctly.
3. Encrypted personal VPN service at router level
Gone are the days when you have to be a large corporation to afford a Virtual Private Network (VPN), now one can be yours for a small monthly fee. A personal VPN is one of the best ways to prevent hackers from attacking your network because is anonymises your true location with a proxied IP address and adds a wall of strong encryption to protect your network traffic.
4. Disable the “Admin via Wireless” feature
When this feature is disabled only someone who is physically connected to your router via an Ethernet cable can access the admin features of your wireless router.
Of course, there are some devious and persistent hackers out there who will penetrate your network whatever you do, but following the advice in these tips will make your networker a much harder target to crack.
