So my home internet is using TM Unifi. It comes with a terminal (Huawei) and a router (Tplink Archer C1200). So I bought the Deco M4 2 packs to enhance the wireless range. I have no problem in setting up the Deco M4 with the Unifi router rather I have done it many times, due to power outage or router restart or down. So the problem is this, every time when the (TPLink Archer C1200) internet is down or power outage or the router is shut down. Whenever it is recovered, the Deco M4 will always show Red Solid LED light. No matter, I try to restart or reboot the Deco M4 or the entire network devices, including the terminal and router, the dice will never work. Every single time I have to delete the SSID and recreate the network or reset the Deco M4. Then only it will work. It is so frustrating. It is like the Deco M4 is not smart enough to recover by itself. Really hope the community can help me out with this.
