Sudden Loss of Upload Speed and Intermittent Loss of Broadband

On Monday night my connection suddenly dropped out. For the rest of the night my connection was intermittent

Previous to Monday I consistently got max speeds for my 360-382 down and 36 wired and over wifi. From Today (Tuesday) my download speed is all over the place. Anywhere from 10mb to full speed. Upload speed doesn't get over 10, but often only 1meg.

Im on a hub 3. I've done the usual reset. Cable into the router seems fine.

VM Status check does not detect any errors. 

Getting loads of errors in the network log:

Re: Sudden Loss of Upload Speed and Intermittent Loss of Broadband

Could you post the 'Downstream' and 'Upstream' tab data?

We can have a look for any oddities in the stats.

Re: Sudden Loss of Upload Speed and Intermittent Loss of Broadband

Power levels look ok.

Some of your channels, however, appear to have a large number of errors. If these have built up over a short period of time this points to an issue with your line.

It could also be a hardware (HUB) issue.
