Most noobies with a wireless router in their house have no idea whether or not their wireless network is secure. And while I could sit here and write a bunch of complicated steps on how to secure the router, I think everything really boils down to these 3 basic steps.
1. Don’t use an obvious wireless network name.
If you don’t want people to know which wireless network belongs to you, then don’t use something obvious like your last name as your wireless network name. Use your favorite breakfast cereal or your favorite fruit. Heck, I’ve even seen people name their wireless networks after something that scares people like “Connect To This And Get a Virus”. Be creative!
2. Assign a password to your wireless network.
While most people will never get hacked through their wireless network, there’s no good reason not to secure your network with a password. I mean, even if you live in a safe neighborhood, you lock your doors at night, right? Bonus tip: Don’t use a password that you use anywhere else. Down the road, you may want to share your wireless network password with a house guest.
3. Secure the wireless router itself.
I see this one everywhere. People secure their wireless network with a password but leave the actual wireless device wide open. Yes, your wireless device itself has a username and password and it is usually assigned one by default from the factory. And the default is the same for every other person with the same device. Do yourself a favor. Find the change password function and select, at a minimum, a new password. And again, this should be a different password than the one chosen in step 2 above.
