I have a network of  3 Archer C4000 and 6 Archer A7. All of the routers are connected by CAT6 cable. The home router is a C4000 v3.0 with the latest firmware (as are the A7s). Is there a way to record the time when lost signals on individual routers occur and the duration of those down periods. I have one router (an A7) that has started to drop out periodically. I can see it when it happens if I am actively watching it on the network which is good. But, the clients are rental cabins so I may be getting outages while the clients are away from the network.
