I have an extender RE-305 V3.0 whose serial number is 220A086000879 EU/3.0.The extender is not getting connected to the 5Ghz host network of the router tp-link archer c-6 V3.20 (Firmware version 1.0.5 Build 20201117 rel.41066(5553) ). The 5Ghz light in the extender is not getting on. RMA has been provided 2 times, still, the problem is not solved. please solve my problem. The problem gets solved with the smart connect feature off on the router but by disabling the Smart connect, it's not convenient for everyone to use .please tell me how do i connect the extender to the 5 GHz network of Archer C6 with the smart connect feature on the router
I will be highly grateful to you if you solve my problem as soon as possible.
