It’s an interesting question and is why I decided to write this short article on it. Short answer is no. Long answer is – it depends on a lot of different things like the type of encryption you use, the complexity of your password and so on.
In short, the best two things you can do to protect your WiFi connection are:
- If you have an old WiFi router, make sure you’re not using WEP encryption as that takes about 8 minutes to crack. The solution: If your current WiFi router has WPA2, use it. If not then get one.
- Make sure your password is long. Longer than 10 characters. Include numbers and capital letters, even things like $#%. Why? The easiest to do and most common WiFi cracking method is either brute force or dictionary attack. The longer the password the better. Each additional character multiplies the amount of time such an attack would take. For example, 10 characters could take a few years. 12 characters could take 10 years.
What’s there to worry about then? Years? Yes, but you could also be unlucky and it could take a week instead. The point is, the longer the maximum is, the less likely it will happen sooner. It’s like a guessing game. Is the number between 1 and 100 or 1 and 100000? Which game will likely be won first?
