Hi, we have an internet connection via WIMAX in one of our systems.
The Teltonika router is cascaded to the POE switch and connects to it via a PPPOE protocol.
When the connection fails, the Teltonika Router switches to mobile.
And in fact we see the relative IP in the choice of the WAN, but when the ADSL returns to work the device does not return to the WIRED configuration.
What could be the cause of this inconvenience?
The device has firmware ver .: RUT9XX_R_00.06.04.5 as firmware
