That would > be very useful for monitor mode and good for IBSS. I just received an answer from Ralink about this issue, --- 1. For 11b/g based chips rt2500, rt2570, rt61, rt73 doesn't implement this. 2. For 11n based chips, there is one MAC register have to enable to have this feature. But, Word 2 of RXWI will put the timestamp and the RSSI will put to Word 3. The original Word 3 SNR will disappear and replace by RSSI. --- As for the timestamps in 2400 and rt2800, they are both in 32bits, so I am not sure how reliable they will be for IBSS. Ivo
