It is not prudent to connect to one of the hundreds of thousands of active Wi-Fi networks available in the world by setting the connection parameter of your laptop or smartphone to automatic mode.
You should check technology adopted by the network security system. Wi-Fi Protected Access Version 2 (WPA 2) is the latest network security system which will also connect at a fast pace. WPA 2 will not work on old networking cards.
WPA 2 requires the testing and certification by Wi-Fi Alliance, industry association which implements the elements of wireless standards. WPA 2 has eliminated all the serious drawbacks associated with earlier WPA.
Use secured website mode
You should not share your private and sensitive information on websites that are not using encrypted technology. You can find whether a website is secured or not by noticing https at the beginning instead of http.
It is common that https sites will employ a minimum of 256 bit encrypted technology for data transfer through their sites. As the data is encrypted, it is not possible to encode the data even if someone is able to access the data you send across the wireless network.
Banking and shopping sites adopt secured technologies on their sites. You can also observe the same on Gmail, Hotmail, Facebook and other websites.
