Low bandwidth after upgrade to M500 from M350

Hi, I'm expeirencing a drop in bandwidth since upgrading to M500 from M350. Everytime I carry out a speed test, connect via a network cable I'm only seeing download speeds of ~100Mbps. Before the upgrade I was seeing at least double that during the day and higher speeds 300+ later on in the evening. I've tried rebooting the superHub3 and all my network equipment, as I run the superHub3 in modem mode and still no joy.

Below is my current router status, hopefully someone can shed some light on the issue and a way to resolve it.

Re: Low bandwidth after upgrade to M500 from M350

Downstream power levels are too low! - You'll need an engineer to fix it!

VM will be able to book this through here when they see it!

Re: Low bandwidth after upgrade to M500 from M350

Cheers lotharmat, I gave VM a call this morning and they sent some "signals" to the box and restarted it and didnt make any difference so I have an engineer booked to come out and take a look.
