I've run into a problem that I am trying to workaround. It seems that when I reboot my router, or change a setting that requires the wireless (ath0) interface to restart, wireless clients can no longer re-connect.
I have confirmed this with an ASUS transformer tablet as well as several TrendNET webcams. Oddly enough, Windows 7 does not seem to be affected. On the Transformer, if I turn-off Wi-Fi, and then turn it back on, it reconnects fine. With the webcams, restarting them (power cycle is only way), does the trick.
As you might imagine, this is a problem if I am not on-site as that is why I have the cameras in the first place.
I've tried telnetting in an disabling the wireless interface and then re-enabling it, but that does not work. As a matter of fact, that is actually one way to reproduce the issue. This also means that the several WiFi dropout scripts in the Wiki won't work either. ?
