Our TP-Link TD-W8970 router is WiFi and Ethernet connected. WiFi connection to the router is lost by all WiFi users (Desktop, 4 phones and 4 laptops) approx three times a week at totally random times. When WiFi connection is lost the Ethernet machine is unaffected and remains connected to the BB and interrogation of the router from the Ethernet machine shows the router status including WiFi status as normal.
WiFi is re-established in 3-8 mins. The TP-Link router is 1 week old and the previous Netgear router suffered the same problem. I suspect something is interfering with my WiFi transmitted signal. Operation and use of the central heating boiler, house alarm, cordless phone, mobile phones and car key fobs do not appear to influence the loss of the router WiFi.
Is there anything I can use to assess the radio frequencies in my house to understand better why I am loosing router WiFi signal. Any other ideas would be welcomed.
