Hi, My name is John I got a degree in A.S. in Cisco networking back in 2004 and felt like I didn't learn nothing. I tough myself wireless routers setting them up and setting up wireless networks for home users. I am looking for a book to teach me as I am just a beginner walking into class for the first time and go from the ground up. I been a A+ tech for nearly 15 years. The classes was so bad that I shy away from med to large networking jobs as I am scared to death to take them on because of all this. I feel pretty confident when working with home users as they isn't that much to deal with. What book do you recommend me getting to get me back on track and give me the confident to tackle networking jobs no matter the size?
