So it seems as if I have come to a roadblock. My house requires 4 wireless access points / routers in order to have decent signal in key places around the house. I currently have a mix of G + N routers and a mix of G + N capable computers. Currently, our cable hookup comes in through the basement, and that is where our internet lives... in the basement. However, if I were to have wires run throughout the house to the places where the wireless access points should be located, I am wondering whether this configuration would provide for optimal speed and cost. If I take the cable modem --> 4 port router/switch --> 24 port netgear 10/100/1000 switch/hub (what's the difference?) and then from the netgear have an assortment of wired connections and wireless routers/switches that I already own (some gigabit, some not) placed throughout the house where I need them. I have heard that having multiple routers/switches/hubs on the network slows down the overall speed of the network. Is this true? Also, if I walk from room to room with my laptop, will it automatically pick the best wirless router to take the signal from, like a cell tower? what if I am on a wireless voip phone? will it be able to switch access points without interruption? if I have some non - N routers on the network, does this cause the N routers to function at slower G speeds? I know that this is a lot of questions, but thank you for helping.
