Sorry about your disconnections, I'll do my best to help.
I have tested your connection but I honestly cannot see any errors/faults on the network that would result in loss of broadband.
I hope you don't mind me asking a few questions so I can get a clearer picture of what's happening from your perspective:
Is more than one device affected by these disconnections?
Does this affect wired or wireless connections (or both)?
Does the Hub require a reboot to restore connectivity?
How often are the disconnections occurring?
As soon as I see your posted reply I'll see if we can determine the cause and hopefully take the appropriate corrective action. Thanks for coming to our Forum for help with this, welcome on board
