I have recently been supplied with a BT smarthub 2 in the move away from analog phones. My two TPLink RE450 devices are no longer working after been reset and connect to the new router. One does not provide any internet at all and the other, newer one seems Ok at times and then also has no internet. I have tried them in both mesh mode and with unique SSID's.
I am thinking that its maybe down to the smart feature of the hub changing channels and considering just selecting a fixed channel. Has anyone else had this problem and would this be a sensible thing to do.
I would use a wifi analyser on phone and find channels in use near you then select a free or less congested channel. certainly move off auto/smart to specific channel
