Can a m3w be used without the deco main unit? I am still unable to get my M4R to work. I even got a new router with no success. Very dissatisfied with the system!!
Can the TP-Link Deco M3W be used without a main Deco unit, and how can I troubleshoot my M4R unit?
No, the TP-Link Deco M3W cannot be used as a standalone router. It is designed specifically as an add-on unit for an existing TP-Link Deco Mesh Wi-Fi system. It requires a main Deco unit (such as a Deco M4, M5, or M9 Plus) to establish the network; it cannot connect directly to a non-Deco router via Wi-Fi to create a mesh.
Regarding your Deco M4R issues, if it is not responding even with a new router, you should perform a factory reset:
If you are trying to use the M4R as your main router, ensure it is connected via Ethernet cable to your modem and that you are following the setup steps in the Deco app. If the M4R is still not working, it may be a hardware fault or a configuration mismatch with your Internet Service Provider (ISP) settings.
