I have an exisiting easymesh network with an Archer AX55(MAIN) and 3 RE605X devices. I have been working to add a satellite router using ethernet backhaul to the network to create better coverage and speeds in certain areas. I purchased a second AX55 and added it to the mesh, and ran a hardline to its new location. Initally i added to the easymesh while the devices where right next to eachother. Then powered down the satellite router and moved it to its permanent location and connected the ethernet back haul to one of the LAN1 Port and powered it up. Once it rejoined the easymesh network i could see that it was using the ethernet backhaul. However soon after it seems to created a network storm that started crushing the network causing the network speed to drop drastically, and making the Main Routers web Console or Access via the Tether app unusable. As soon as i disconnected the ethernet cable everything cam back and the router switched over to wireless and joined the easymesh. When the satellite router is connected to the easy mesh wirelessly there seems to be no issues, only when its connected directly via ethernet. I have tried using the WAN and Various LAN ports on the Satellite router all have the same result. Anyone else experience a similar issue. I have an IT ticket open as i had a firmware upgrade issue for the satellite router, which i updated to include this info after the upgrade was successful.
