I recently got a 2.5Gbps hardware agent to replace my old yellow agent.
The new hardware agent seems to be constantly rebooting, as marked on the dashboard. Sometimes it seems like it is actually rebooting; mostly it seems the dashboard is just incorrect. This "rebooting" can last well over 60 minutes. That amount of time offline due to random "reboots" makes it much less useful for any reliable monitoring.
However, it also seems to not be logging times when I know internet was offline, like when i swapped cables or when I rebooted the router.
Maybe I have it set up incorrectly? There was no included setup instructions, only the activation email, and activation was successful.
So far, this new hardware agent has been a huge disappointment, but I am hoping it is just due to user error.
