Not > very scientific so it might as well be 2.75MB/s :) 54Mb/s is 6,75MB/s, but you'll never reach that speed on 802.11g. No matter what card, what driver :) 3MB/s is probably sth around the maximum speed *in practice*.

I've tons of N-PHY (and not only) devices around, so don't really need any donate of that devices. I just have to find time for this. -- Rafał -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
