Question: Which wireless standard should I use?

The most popular wireless standards are 802.11g and 802.11 pre-n (802.11n draft). However I would recommend 802.11g since it’s a mature technology and the price is reasonable.

As for 802.11 pre-n or 802.11n draft products that based on MIMO technology, since the standard is not yet finalized, product price is considered high and not sure whether it’s compatible with finalized 802.11n standard, I don’t recommend using it unless you really need a high speed network.
