Here's a new task i am assigned now, i have to setup a wirless LAN here as we have around 10 laptop users, plus visitors also bring there laptops so i have to eliminate those wire issues. What initially i want from you people is little help in setting this WiFi LAN.

I wanted to know how i am going to configure, installation & setup procedures. What are the security issues in it?. I am couting on you guys once again.Obviously main thing what hardware i required for this ? Do i be needing AP only or anything else is needed for setup?
