Last week I talked about traveling with your electronics. In that episode, I mentioned that connecting to an unsecured or unofficial WiFi network at the airport is a really bad idea. There are many reasons you wouldn’t want to do this and today I’ll explain why.

Types of Wireless Networks
Let’s look at what an unsecured network is. Generally you can call a network “unsecure” if there is no password or login credentials needed to access it. You just get on and surf the internet. These types of networks can still be found in many places, but in recent years the trend has been towards security (thank goodness).

    Terrible advice in the original article and the comments that follow. For the record: hackers can just as easily snoop your info over 'secured' public wifi as over 'unsecured', because (1) they can usually get the password for the price of a coffee -- public wifi passwords are never secret, and (2) every wifi encryption scheme has been cracked. And in response to the comments, no the iPad is not immune. (As if!) Thinking that if you don't have to type your password, it doesn't get sent, is ridiculous and false. Even if you don't type it, in the course of automatically logging in your password will often get sent, sometimes without even any encryption.
