Wifi is something we use in everyday life, from home, work, a restaurant, to the coffee shop down the street. But I wanted to speak a little bit about our home Wifi connection. Did you know that approximately 80% of routers and Wifi broadcasts are insecure? This can be due to multiple reasons, such as; Using a weak password, using a password that's easily guessable(such as your phone number), not using the correct Wifi protection, leaving WPS active when not in use, and the most common problem that is leaving your router credentials set to default(usually after purchasing a Range Extender or a Router from the store).

So the question is, what can be done? First off, when your ISP(Internet Service Provider) initially installed your services at your home, they should have given you a 12 digit numeric passcode along with your SSID(Service Set Identifier, AKA your Wifi name), this should be kept in a safe place and not given out to neighbours, as they're able to reach a 2.4GHz network from a fair distance away (typically a couple of houses down). Don't change your wifi password to the name of your dog, cat, or great uncle. Majority of the time you're causing a massive flaw in your home network security by doing this. A 12 digit numeric password has 8916100400000 combinations available, it's extremely unlikely this will ever get cracked by brute force(comparing a password list to your password).

Second, you want to be sure you're using the correct Wifi protection settings, using WPA(2)-Personal(PSK), is best in today's day and age. Be sure the network is not Open or using WEP. Also, if you're not using the WPS(Wi-Fi Protected Setup) then there is no reason to leave this active, as it just leaves your network open to more vulnerabilities.

Last but not least, If you've recently purchased a range extender or router on your own, be sure to change the default login credentials to something secure, write them down, and store them in a safe place.

A great article guide with valuable information. The more we know about cyber security, the greater chance of preventing a cyber attack on our home broadband connection. Thank you for posting this Dan. I'll be sure to change the router's cresdentials to a 12 digit numerical password.

1) Don't broadcast the password scheme you plan on using, you've just created a profile for brute-forcing your own system.
2) Alphanumeric would be better.
