I need some help understanding all of this router stuff. I am pretty basic when it comes to the complexities of the internet and the way it works so please keep it simple. I live in an apartment and my roommate would like to share the internet connection. I have a 3 meg cable internet connection hooked up to my computer in my room. No internet is his room. We called the internet provider, Charter, and the Charter guy said that our best bet would be to get a router. Now how do these router things work? I have heard of them before but I have never had to mess with them. Plus how secure are these things? What is the best, wireless or other types? See, I really do not know much about all of this stuff. Sorry for being computer illiterate. I rather rebuild a small block than have to try to figure out the internet. Thanks for any help!
