I bet half your problem is that half your packets are going in/out of a disconnected antenna. Antenna profile: [1] tx 8543738 rx 4922481 [2] tx 544837 rx 14216 See? :) Try sysctl dev.ath.0.diversity=3D0 sysctl dev.ath.0.txantenna=3D1 sysctl dev.ath.0.rxantenna=3D1 See if that improves things. If not, try antennas =3D 2. Adrian
