I have a client that we installed a MR400 as they needed to use a 4G backup supplied by their ISP and the ISP couldn't get their provided modem to work with the 4G at all.

Anyway its been running for a while and all was going good until recently. I even tested failover and failback when I first installed it and it worked perfect.

If the device switches to 4G as a backup because the ipoe (Ethernet) internet goes down its not switching back to the ipoe when its back up. Operation Mode is set to Wireless Router Mode not 3G/4G Router.

Under Internet connection its set for 3G/4G to be enabled as backup However as seen the ipoe connection is back up (I have whited out the IPs obviously)

Yet its still using the 4G as below...
