802.11n Finally Ratified
It only took them six years to ratify the new wireless standard </sarcasm> so we now have four wireless standards. This will undoubtedly cause more confusion among the consumer as to what the heck the difference is between 802.11a, 802.11b, 802.11g and 802.11n are, along with speed and compatibility differences/issues between them all.
All I know is that since I use the WiFi at my house primarily for 'net access, 802.11g is plenty fast for my needs. For any file serving/moving in my house, it's all over wired ethernet anyway (which is faster than 802.11n -- or at least lower latency and overhead on a 100mbs connection). While my laptop has a 802.11n card in it (a draft-spec), I probably won't be moving to a 802.11n router until there are a lot more on the DD-WRT supported list.
Just the same, here's a good guide on buying a new router and some brief differences between the specs.
