Yes. It's a dual band chip, but you only get to choose one band at a time. Yes, there are limited keycache slot chips. I don't remember if the hardware limit is 32 or 64 clients. > And are the numbers in the 'power consumption' analysis > (http://linuxwireless.org/en/users/Drivers/ath9k/power-consumption) > for STA mode or AP mode? The 'PS On' configuration implies that this > is for an STA mode but I wanted to confirm. You should always do your own power consumption tests. It differs based on operating mode, environment, TX rate selection/power, what kind of amplifiers and other circuitry are on the NIC, etc. Adrian -- 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
