we are simply not able to deliver RCPI, because we have no idea how RSSI is measured for the ZD1211 device. We had discussions with the vendor developers, but it seemed that their understanding was not really more advanced than our's. There is the same issue for signal quality and signal-to-noise ratio. -- Uli Kunitz - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
