In an ideal world they would be at zero and stay there. To zero them can you reboot the Hub using this method and then keep an eye on the counts.
Try a reboot using this method ...
Before you retire for the night can you do a 5 minute reboot on the Hub to see if the Hub can renegotiate a decent connection.
Switch the Hub off using the small switch on the rear of the Hub next to the power cord and pull the PSU plug from the wall socket.
Give it a good 5 minutes put the plug back in and switch the Hub back on.
Allow the Hub a few minutes to fully restart then check the counts again.
Can you set up a Broadband Quality Monitor (BQM) at thinkbroadband.com - this will give you an insight into what is happening with the signal at the other side of the Hub, it will take a few hours to get any kind of trend showing although you should post the link straight away.
Post a link to your BQM on here.

Click the lower link (Share Live Graph) then click generate.
