    The 151117 firmware doesn't work for me. I'm using a Huawei E3276 USB modem...

    My last dialog with TP-Link was end of March. My Internet connection was really bad, and I wanted to leave it that way till they fixed the fail-over problem. At that time the 151117 release appeared (to me) to have a memory leak of some sort. After about 3 weeks of use and failing over a dozen times a day, it would stop failing over. I was approaching a point where I would be gone for an extended period, so I fixed the WAN issue. About the same time TP-Link support pretty much said I would have to wait till the next production release and see if it was fixed then. I have not had time to go back to it.
