Internet keeps disconnecting

Hi,

I have a superhub 3 switched to modem mode connected to my asus router - I used to have this issue before I switched it to modem mode and connected to my router but still seem to be getting it even with the router. The issue is that the internet keeps losing connection across both a wired ethernet connection and WiFi connected devices.

Looking in the network logs I see a lot of critical errors around the times I lose connection. Here are the logs (currently running the superhub 3 in modem mode):

The levels I posted above weren't actually during the time the dropouts were happening... These are the levels:
