I don't think there is currently any configuration option for doing that in the driver or an easy mechanism for doing that. If you are running wpa_supplicant manually, you could configure a network block with only some of the channels marked for scanning (scan_freq parameter). That may end up doing this kind of selection in practice. However, I do not think that forcing 5 GHz connection is really that useful in most cases; giving an option to prefer 5 GHz band may, however, be useful (or some other additional mechanism for preferring some APs over others). I would assume you would still like to connect even if some location can only see the 2.4 GHz BSS. I would prefer to make this type of optimizations automatic whenever possible, i.e., there really should not be need for the end user to have to have this type of knowledge. Do you happen to know why the 5 GHz band is better in your particular case? Is it just because the APs on 2.4 GHz get more users? - Jouni _______________________________________________ ath9k-devel mailing list [email protected] https://lists.ath9k.org/mailman/listinfo/ath9k-devel
