Abysmally slow internet

Hi all. Was just wondering what to do with the internet when all these notices happens? Factory reset the superhub a few days ago and it was fine for a few days and last night has probably been the worse.

Straight all afternoon til this morning I've only gotten 1-10mbps compared to promised 1GB. These notices keep popping up on the virgin log, not really sure what they are. Already have power cycled it, factory reset it, restarted it. Not sure what else to do!
