I don't think these two are connected - the erroneous country setting is probably just the reason why I can't try the 5GHz band and thus can't verify if the packet loss occurs there as well. Thanks for your explanations - I will try to get CRDA and regdb running and will try again with the 5GHz band. One other thing comes to mind: this 802.11n card has two antenna connectors, and both are actually connected to pigtails (which are probably not mounted in correct distance according to wavelenght, but that shouldn't cause packet loss). However, it might be possible that one of the antennas has a poor connection, is misaligned with the clients, or whatever. What I couldn't find in ath9k is an option for user-controlled antenna diversity (comparable to madwifi). How can I selectively disable antenna usage and/or set them for RX or TX mode only? best regards, Rene -- 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
