Diagnosing lost packets profile

I am intermittently loosing BB. Fiber to the cabinet, BT modem, Ethernet to the TP archer c50 router. The attached snap shot shows this drop out at 22:00 and between 23:00-24:00. There are also a few sporadic small lost packets occurring during the day.

Does the profile of this drop out indicate any specific part/component of the system ?
Specifically the jagged lost packet profile fluctuating between 90% and 100%.
Ignore the drop out at 08:30, that was me trying a few things out.
Any help would be appreciated.
