When I upgraded my Sky Q dual channel modem router, i found that the wi-fi smart plugs and camera I controlled via my iphone no longer worked. I established that this was due to the new modem operating at 5Ghz so I reconfigured it to run a parallel 2.4 Ghz channel. However the set-up procedure on the iphone apps failed - they would only find the 5Ghz channel. So I thought I'd try using a separate router at 2.4Ghz and bought the TP-Link 300Mbps router. But I am struggling to connect it to my network. ANy help would be gratefully received!
