WiFi b or g might be fine for pushing around a few bits here and there, but until the powers that be figure out a 802.11n
standard, you're stuck with MIMO
routers if you need bitrates that rival LAN speeds to throw
around HD video and the like. Buffalo is pushing out a new SuperG product line that includes the A/G High Power Smart
Router and the A/G High Power USB Adapter. The SuperG chipsets, from Atheros, can push 240Mbps and include 802.11a
support. The router will go for $99 and the adapter for $79, and both should be available in February.
