Help required regarding my monitor

Could someone shed some light on the blip I have on my graph between 6-11pm every night? It happens even when I am not really using the line and I would appreciate any input.

If you are sure nothing is moving data across your line, then the zone of raised latency (not really a blip as they are generally shorter periods) suggests increased latency due to congestion and some packets delayed long enough to be dropped

Thanks Andrew

The usage on the line is constant so its not as if everyone just came home and started using the bandwidth, it is happening every night too.

If this is congestion what are the best moves to get it fixed?

Content use of broadband is very rare, you need to try stopping this constant use and see if that helps.

As for congestion, if its ISP side as opposed to you filling the line up yourself then down to them to add more capacity

Maybe a (non-internet) TV, or even a smart (internet-capable) TV being turned on for that period? Possibly not even yours, it could be next door's. Also, not necessarily the main home TV.

I should clarify constant use, I have a remote lyric device similar to a hive product that is connected 24/7 [wireless] and a networked printer. Maybe I was wrong describing it like that.

As of now I have removed everything that is actually using the router to see what happens and I will report back again tomorrow.

Thank you for the help, I really appreciate it.
