Hello List, I am having a problem getting Rx diversity to work with both ar5213 and ar5413. What I have found is that the fast diversity works great for receiving 802.11b (i.e. CCK) modulations. But fast diversity for OFDM just does not seem to work (and yes diversity is turned ON). I am using controlled conditions, i.e. cable and attenuators, and find that basically on the non-default antenna there is effectively 30dB attenuation. This means that to successfully receive an OFDM frame on the non-default antenna the signal has to be 30dBm above the noise floor! Not very useful... Basically Rx diversity for 802.11a 5GHz and pure 802.11g is a no-go.
Does anyone know if this should work - or perhaps Rx diversity for OFDM is just a no-go? BTW - I've tried this with ath5k/mac80211 as well as madwifi and openhal, as well as the old closed source madwifi hal. They all behave the same way. Adrian - I see you have made some changes to FreeBSD related to this - do you have any idea if this *should* work? Anyone else? Thanks Brett
