Recently upgraded to 500mb from 200mb but I'm not getting the promised speeds. I've tried this on ethernet and wireless which is up and down on speedtest.net. Most I've had is 460mb dips down to about 200mb with lowest this morning being 4mb.

What speed do you get on https://speedtest.samknows.com/ with direct wired connection from PC to router using a Cat 5e cable or better with a 1Gbps Ethernet capable network card?

[Labowl1989]

Tops out at 405mb but can drop to about 360mb. When I was on 200mb I used to get 220mb consistently which is very frustrating.

You power levels are a bit high on the download but still within specifications.

Can you please set up a Broadband Quality Monitor (BQM) at thinkbroadband.com.

Post a 'Live Link' to your BQM on here asap.

Under your graph you just created Click (Share Live Graph) then click generate.

Copy the text in the Direct Link box and paste it on here

With that many errors in a short period of time I'd suggest there is an issue with your line.
