The "auto bond0" stanza is required, else bond0 won't be brought up. The "wpa-bridge bond0" stanza is required to inform wpa_supplicant that wifi link-level packets will arrive on bond0, not on wlan0. The "bond-give-a-chance 10" stanza is required to give a chance for wifi authentication to succeed. Save
