Motorola/Arris NVG510's wifi security only goes up to WPA?

Hello. I noticed my client's AT&T U-Verse (slow DSL speeds) modem+router device (Motorola/Arris NVG510; software v9.0.6h2d45; 8/11/2014)'s wireless security can only go up to WPA. IIRC, WPA is crackable. Is there no WPA2, SPK, etc.? Thank you in advance. :) -- Ant @ http://AQFL.net and http://AntFarm.home.dhs.org
