Hi, signed up a couple of months back and speeds have been fantastic until this morning, where test results have been coming in at a mere 10-20% of the usual rate. Still having the same issues now, even after rebooting the modem.

You have a fault (probably noise). Down channels 5 & 6 are borked - low signal noise ratio's and too many RS errors - also you upstream power levels are all at the maximum limit and may be struggling.
Call it in as a fault and see if they can see it - or wait here for a day or two until a VM mod picks up the thread and offers to help.

Thanks, John. Not a fan of offshore call centres so I think I'll hang on here until some help arrives.

Abysmal speed issues still occurring as of this morning. Thankfully we're only on a monthly rolling contract if things don't get resolved.

Hi there @manaomanao. 

We sure do need to take a look into this, I am going to pop you a PM so that we can get some account details. 

Kind Regards
