Looks like your router is an Atheros SoC router, for
my AR-unit, mobile broadband I had to use build 25760.
Newer builds had broken something in mobile broadband dongle support. _________________ EA6900 v3.0-r33555 std ░ WZR-HP-AG300H-DD-WRT v3.0-r33529 std ░ WHR3-G54 v3.0-r29193 mini ░ WLI-TX4-G54HP ░ WBMR-HP-GNV2 ░ TL-MR3420v²

Now a days due to LTE feasible speed upto 50 Mbps is possible over USB LTE Modem/Dongal/Routers with Battery backup. Problem with this devices is they do not have ethernet interface, they use only wireless ethernet or usb over ethernet. Devices like Alcatel MW40CJ, ZTE MF90, Huawei E5573 etc.
There are DD WRT supported routers with USB ports, but I have not found any DD WRT image that supports USB over Ethernet Emulation.
If anyone knows about this please share, otherwise a firmware with that support will be appreciated.
