    Disadvantages over what? No encryption, WEP, WPA1. Also how is WPA2 configured, PSK, certificates, authentication server? – mikeazo Apr 30 '14 at 14:53

You could have just tried google!

The only disadvantage of WPA2 (when comparing to WPA) is in the amount of processing power that it needs in order to protect your network. This translates to a direct need for more powerful hardware or suffer a reduction in network performance for heavily used networks. This is an issue with older access points which were designed and built prior to WPA2 and only implemented WPA2 via a firmware upgrade. Most of the more recent access points have been equipped with more capable hardware to minimize the speed degradation.

    Thanks Snox - using quoted information is fine as long as it is attributed. Your update is fine on this one - please go and do the same for your other answers. I would suggest that in the longer term you don't solely post answers copy and pasted from elsewhere, though... – Rory Alsop Apr 30 '14 at 15:02
