Internet dropping out

[AVRD24]

The Sky troubleshoot tests say that there are no issues with the wifi/broadband but the connection is dropping out regularly on laptops. Router stats copied below. Any suggestions of what the issue might be and how to resolve would be welcome!

Your router stats suggest the WiFi radios are dropping or changing channel due to interference. Has anything changed recently that could have caused this such as changes in appliances, router location, neighbour's WiFi etc.
