Product specifications are enticing ... but what use is a bit disappointing. I looked for a solution to provide access relief 3G / 4G when ADSL failure, the product allows it and does it well ... the first time! because then it must reboot for the new failover is automatic, too bad. The DHCP Reservation on the latest version of firmware can record 10 addresses, the following pages do not allow saving changes !!! It is impossible to assign a device in the DMZ ... Finally, I only used as a modem 3G / 4G WAN second entry on a TP Link router that handles switch to him as ADSL falls and there it works. In short, a good modem 3G / 4G but not a real solution, especially not as a router for reliable backup connection.
