    Disadvantages over what? No encryption, WEP, WPA1. Also how is WPA2 configured, PSK, certificates, authentication server? – mikeazo Apr 30 '14 at 14:53
  • You're given the choice between an overly complicated (Enterprise) solution and a weak (personal) solution. – CodesInChaos Apr 30 '14 at 15:53

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
