Thank you for your post Rizuk and sorry to hear you're experiencing some broadband issues.
Could we please confirm if the tests provided is through a wired or wireless connection? If through a wireless connection could we please ask that you post your tests with a device connected through a wired connection?
Could we also please confirm if your Hub is in modem mode? If this is the case could we please ask if you can put the Hub back on router mode and provide us the tests in this mode as well? We would need to take away the possibility it may be to do with any third party equipment as if we end up booking an engineer appointment, if they arrive and it was third party equipment causing the fault this would then risk you being charged for the visit which we'd like to avoid.
How are your devices connected to the internet? Is this via WiFi or Ethernet.
Ethernet and WiFi
When your devices lose connection do they all go at the same time.
Yes, all devices lose connection to the Internet, internally they are fine - I can connect to my NAS from my computer just fine when this happens. It's the cable modem that drops the connection, as you can see from the logs and the external ping graphs.
Do all the light show on the Ethernet ports?
I'm sorry it's not clear to me what you're asking here?
