80Mbps on M200 since moving house

In previous property where we first started with Virgin, download/upload speeds were absolutely fine, consistently hitting the 200Mbps.

Since we moved, we have only been getting 80Mbps regularly (occasionaly it will go up to 100Mbps but not for long). This is below the minimum expected when I checked the speed charts.

I have followed the steps (wired test with Cat6, factory reset of router) advised on the website, and checking my service on the website says there are no faults.

Wireless speed is showing the same, so speed out of the router is pretty much 1-1 with what we are getting to the router.

Re: 80Mbps on M200 since moving house

The downstream power levels on some of your channels are out of spec (-6 to +10 is in spec).

You shouldn't really change anything yourself.

An engineer visit would be required, where they would probably fit an 8dB forward path equalizer between the HUB and cable to the wall socket, to reduce the power level by 8dB across your downstream channels, whilst keeping your upstream levels 'as is'.

Re: 80Mbps on M200 since moving house

Thank you for the quick information! I'll book an engineer visit to have a look at what's going on.

I assume it was a self install?

When an engineer installs the kit they check the levels as well so probably would have been picked up by them!

Re: 80Mbps on M200 since moving house

Yep just plugged it in as there was already a Virgin media connection to the house.
