Optimal wireless security settings

[ipfftw]

I was talking to someone recently about their keypair regeneration time settings on a crappy ddwrt (no offence, but its NO pfsense). He seemed to set them intentionally very low, and I was concerned as the pfsense defaults are set to several orders of magnitude more time than his recommendations. I suppose there is a speed hit with more negotiation, so i was wondering what pfsense peoples thought about optimal wireless settings. Specifically, settings that can be changed on pfsense to increase wireless security from cracking and the various brute forces that are our there.

any input appreciated! I am posting the relevant sections from pfsense 1.2.3

thanks!
