I have 2 AC86U routers in AiMesh. The main router is on the ground floor and the node is on the first floor with ethernet backhaul mode. There are 25 devices connected to the network, of which 15 are wireless (home appliances with no LAN connection: smart lights, doorbells, etc.. ). Both routers are using the latest FW (220.127.116.11.386_48260), separate SSIDs for 2.4 and 5Ghz WiFi, and smart connect is turned off. The rest of the settings are on default. Sincerely I'm using the system for half a year already but almost every week the main router drops all the WiFi connections, and the devices reconnect to the node (reboot solves the issue). In this situation, the farthest devices receive just minimal signal and randomly appear offline. This issue happens only with WiFi devices, the cabled devices stay connected always. Tried binding the devices to the main router, but in this situation when the WiFi drops they do not reconnect to the node either. Performed hard/factory reset multiple times. Tried switching up the 2 routers or placing them further from each other. Nothing helped. After a couple of days, the main router just disconnects all the wireless devices. I even tried it in Router-AP mode, and the same thing happens. :mad::mad::mad::mad: Before I used 2 TPlink Archer C7 in Router-AP mode and I didn't face this issue. I have no idea what else I could try, and I really hope that someone here can help me.
