Ok so we have 9 computers in the house at the moment, 2 macbooks 3 pc desktops, and 3 pc laptops. We are currently running a 16 mb/sec cable line through a single 4 port router (a dlink dgl-4300) with wireless. the 3 desktops are connected via ethernet, one of the two macbooks uses the last port sometimes but most of the other laptops run wirelessly. Usually at most we have 5-6 computers on at once. 3 desktops and 3 laptops . The router works fine on the second and third floor of the house but its horrible on the first floor + kitchen, and the basement. The router is placed in my room which is on the third floor. would placing the router on the second or maybe even first floor make a difference in the wireless? The router is also a 802.11g router so it kinda can't let the macbooks run wireless on its full potential. My question is how do i satisfy my family? they want a better wireless connection and better networking, for the least amount of money. Should i buy an airport extreme, or any of the new draft n routers? I don't know much about wireless networking but i know the basics. I'm willing to rerun ethernet cords across the house to move the placement of the router or wire a new wireless access point to achieve better service. Thanks guys! Oh yea, one more thing, whats the difference between cat5, cat5e, cat6, and crossover cabling?
