Re: 802.11 a/b/g/??????
In order for a network to be considered a network, several things need to be the same - mainly, the protocols used. In order to form a network, all computers need to be running the same protocols, e.g. TCP/IP and 802.3/802.11g/b/n. The protocol variation used will be dictated by your router, and everything that connects to that router will use the same protocol by the time the signal gets there, randomly swapping protocols in networks is more likely to just slow everything down. I'd assume that most of your computers would have G-band compatible wireless cards, and G-band is the most common band around today. 802.11g is 54mbps. If all your PCs support 802.11n, this can be considerably faster.
