Hi, in order to compare the performance between antenna-diversity on and off I did a quick test with the following sysctl settings: # antenna-diversity on dev.ath.0.diversity=1 # antenna-diversity off dev.ath.0.diversity=0 dev.ath.0.txantenna=1 dev.ath.0.rxantenna=2 The performance was pretty much the same but I noticed that the link-quality reported by my laptop was notable lower with enabled antenna-diversity (AD): ~ 43/70 (AD on) ~ 51/70 (AD off) I've read a few things about AD on Wikipedia and it seems to be a good technique to achieve a better signal quality but OTOH there are people who recommend turning it off to get a better signal quality. So whats actually true here? Thanks, Petar
