Once you have setup your wireless router, it is a good idea to secure it, so that attackers have a harder time getting to your network (if they can get to it at all), and so that people cannot steal your internet, and possibly slow your connection's overall speed. Here are some key tasks to preform in order to secure your network:
- Disable SSID Broadcast - Doing this makes your network virtually invisible to other devices looking for a connection
- Change SSID - Most hackers/attackers know the default SSID for routers. Changing it will make it harder for them to guess your network's name (and knowing the SSID can be half the battle).
- Enable Encryption - This makes it so that you need a password to connect to your router wirelessly. Obviously, setting a password makes it harder for a hacker/attacker to access your network. (I suggest setting a WPA2-PSK rather than WEP, because WEP is able to be cracked)
- Change Router's IP Address - This is another default setting that hackers/attackers find useful. Changing this, just like changing the SSID, will make it harder for people to figure out your network's address (which would give them a better opportunity to change the settings on your router, just as you are now).
- Change Router admin password - If someone somehow gets onto your network, doing this will make a last line of defense against a person changing your router configurations.
- Enabling Wireless MAC Filtering - Doing this will allow you to prevent or allow a specific device or devices connection to your network. (note: not recommended for the regular house hold, because it can be a big hassle for connecting new devices)
Though similar in features, each device has a different way of go about these tasks. If you need further assistance for your particular device, or have any other questions, please feel free to contact me.
After preforming these tasks, your network will be much more secure. I am looking forward to getting feedback on this guide.
