Thank you very much for your detailed information.

For your case, we would like to follow up on your case by email and please have a check of your email box later.

By the way, even though the Ethernet backhaul Is not working anymore, all three Decos still have internet access, right?

And both of the satellite Decos failed to use the Ethernet backhaul, right?

If the Juniper switch is replaced by the TP-Link unmanaged switch again, the Ethernet backhaul would take effect immediately, right

Thank a lot and wait for your reply.
