1.	Solve : WiFi security: n00bie wondering what's the optimum safeguard to use in public??
Answer» Safety Course 101 question: At home I use my desktop COMPUTER for work and school. But now I WANT to start USING my laptop for the same things at a public hot spot. That means I'll be going on the Internet via wi-fi on a daily basis. I understand that when it comes to safe surfing a VPN is something a security concious person should set up on their laptop. Is that TRUE? If so, can you recommend the name of a good VPN? And will the VPN slow down my surf sessions at all as opposed to a hard wired connection?
