I just got a TP-Link ER605 for internet load balancing and failover. I plugged both my internet modems into the WAN1/WAN2 ports on the ER605, plugged my AX55 into the LAN port, all devices connected to the AX55 have internet, but it is impossible to reach the admin page for it (neither by ip or http://tplinkwifi.net or the tether app). I can still reach the admin page of my RE315 range extender, and Tether shows the AX55 is connected, it just won't let me change the settings at all. Is there any way around this? Maybe some setting in the ER605 I am missing?
