WiFi Intermittent Drop

Hello, 

The last month or so, our internet WiFi signal has dropped and stopped broadcasting repeatedly.

Within a few seconds to minutes, it returns.

Any advice would be much appreciated.

Before I have had Pre RS in the four figure, and Post RS in the 5 figure range and 4 to 4 T3 time-outs but currently the router logs look like this;
