So I have vivid 500 and when first installed it was great and I hitting 500-560 download speed in Modem Mode

Over the last month it’s been getting slower, now I only get 200-310 download speed. 
(upload speed is 35-39)

Any suggestions welcome?

Upstream power is too high, its's right on the upper limit of 51. You need an engineer to get this down. BTW, there is a bug in the Hub 3 firmware and the decimal point is in the wrong place for Upstream. So the 5.1 is actually 51 ......

There you go, I was late today.

Thank you all for your help, I shall give them a call and get them to sort it out.
