Power saving mode impacts battery run time; one of our design goals. ips=0 seems to solve with 3.19, but not fully with 4.1-rc7; still some periods of packet loss. I offer to test any rtl8723be changes. (I'm also looking into IBSS, because Sugar desktop relies on ad-hoc. No beacons on creating an IBSS through NetworkManager, but beacons are fine with "iw dev wlan0 ibss join x 2437". But I'm not yet ready to report problem; still some debugging to do.) -- James Cameron http://quozl.linux.org.au/ -- 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
