I'm currently studying a CCENT book and I work in a pretty relaxed environment where I troubleshoot computers on our network. About 100 PC's, 2 servers. I have a pretty solid understanding of how things work, just trying to learn the details and more advanced topics. Wanted to know what I could do at home as well to practice that's not extremely costly to increase my learning. I've got a 2 laptops, 2 netgear wifi routers one not being used, the other one I have set up for two wireless networks, a private and guest. Working on building a good desktop which I hope to have done within a few months. Any suggestions/ideas on setting these machines up in a way that would make me think and increase my knowledge, in more detail, on setting a network up?
