Netgear, Linksys, 2Wire, Dlink and 3Com. They are also easy to
configure.
54Mbps is the maximum speed for 802.11G. I haven't heard of 94Mbps,
but 108Mbps, yes. 108Mbps is the maximum speed for yet to be
verified 802.11N. Some call it Pre-N routers, some call it
extraboost and by some other names.
The difference is only the speeds, other than that, nothing
else.
In reality, you will never achieve those speeds, because it's still
being determined by your ISP.
You will only get those speeds only if you are in a local area
network (that is, transferring files from your desktop to another
PC/laptop)
