Hi guys. My college provides free WiFi internet access, but I dont know anything about how to use a WiFi. I'm completely an illiterate person when it comes to WiFi. *Please tell me how to use wifi service provided in college campus. *The precautions to be taken to avoid hackers/data theft. *Do I need any particular hardware/software ? Please yaar, iss Sakharta abhiyan me meri madat karo.
