Hi,

So my service keeps dropping from time to time. 

My hub is saying Partial Service - DS only

Can anyone help please?

Post up the Upstream data and the network logs as well. But it looks like you have a "noise" problem thagt will require Tech visit to sort. Down channel 4 is suffering - a vast number of RS errors and low SNR - other channels not great either. Try resetting the counts to 0 and watching to see if the start reappearing - they shouldnt

Hi 

So I had a splitter for when I also had Virgin TV. I've unplugged that and restarted the hub (as it had crashed) 

Here is the data from this morn..

Your upstream is on the limit of 51.  Ideally aiming at 45 return and around 0-2db forward.  Have a look from the hub to the wall isolator including the splitter, make sure all connections are clean and tight.  If there is a wideband attenuator fitted try removing it
