I updated my RT-AC66U_B1 to firmware version 3.0.0.4.386_40558 the other day and since then I've been unable to connect it back up to my RT-AC86U (on latest 3.0.0.4.386_40451 firmware) to act as an AIMesh Node. I've tried resetting it then connecting my laptop via ethernet cable to go through the wizard to set it up as a node, it goes through that OK to the point of opening up the admin console of the 86U to complete setup but the 86U never sees it. I've tried wired and wireless, it has a DHCP IP from the 86U and I can connect to the admin console via the 86U's network when connected that way, but it just can't see it as a usable node. Any ideas?
