upgrade to 386.1_2 for my rt-ac88u (router) & rt-ax86u (node). Recently bought ax86u so just want to try as node 1st (replaced rt-ac68u). No issue during firmware upgrade. Both routers reset to default factory after upgrade. However I noticed at times, all devices will connect or switch to my main router instead of node even though those devices near to node (even my smart tv located right beside node). Tried enable roaming assistance but still the same. As of now, I had to force some devices to connect to node. Appreciate any solution for this.
