@limibot. OK. Yes, I do recall reading your earlier post and I’ve done pretty much what you have advised. I can see ip addresses for all three routers when I scan my network but I can only access the banner page of the master router and it doesn’t appear the sub-routers are using backhauling. Must the master
router be connected to the LAN switch by both the WAN and LAN ports, or only the LAN as I currently have? .I guess I’ll keep tinkering.
