Set up using 4G with wan socket as backup
I want to buy one of these and set it up to use 4G by default but switch to wired WAN if 4G fails. The product description says "Wi-Fi router mode – plug an Ethernet cable into the LAN/WAN port for flexible access as a backup option if you can't get a 4G connection" - however in the manual and FAQ it just shows a switch to enable 3G/4G as backup after you have chosedn wi-fi router mode.
I have tried the emulator but on the emulator when you choose to go to router - mode it does a beautifully simulated reboot and then just takes to the main TP Link website :-(
Can anyone confirm that I can use 4G as main WAn and wired connection as backup and if so - how to do it?
Many thanks
