Which u-boot do you use on ES? Maybe it could have some influence. I suspect that power sequence is not working properly as there is missing 32kHz clock and then after some time regulator for wifi is disabled as wifi isn't probed on sdio. What is really strange that why it works on ES and not on A2. I did check schematics and wifi part is the same :). > > Seems like pandaboard connects to another access point, but not to > another computer running hostapd on wl12xx..
