I know that theoretically 802.11g routers, access points, and adapters move data faster than 802.11b ones, but what is the reality of the situation? If I am hooked up to a cable modem, which I believe does not come close to maxing out the speed of my 802.11b gear, what would 802.11g gear get me? If I have other computers wirelessly sharing the internet connection and passing files back and forth, would anything really, in practice, run any faster? Does the 802.11b gear that says it runs at double the speed, 22mbs, really in fact run twice as fast, if the input, e.g. cable modem, is the same?
