I have a ZTE AC30 Global router that works with 3g as well as EvDO.
the firmware has a bug. Once disconnected (due to signal lost or change from 3g to 2g while moving), it never connects back. I mean even once signal is back, it doesnt reconnect on its own. We have to restart modem or manually click connect (Eventhough WAN mode is always on OR On Demand)
The firmware version that has this bug is BD_AC30V2.0.0B02
i am looking for any firmware higher than that
BD_AC30V2.0.0B04
BD_AC30V2.0.0B05
BD_AC30V2.0.0B06
BD_AC30V2.0.0B12
Is there any one who has access to ZTE firmwares ?
