Clients not displaying "dropped connection icon"

If WAN is disconnected or the cable modem goes offline, the connection status icon on the clients laptop/desktop adapter still shows an “active connection” as opposed to an exclamation for “no internet”

Any input as to why this is occurring?

Anyone? Im sure it seems basic but a little help here would be appreciative. Thanks.

It depends on how the operating system is detecting that something is online or not, and has nothing to do with the router. Typically it sees if it is physically connected, if the default gateway is reachable, and if it can reach a resource on the internet.

Thank you Feklar !!!
