Do I have speed issues?

[#1]

I've noticed a drop in speed lately - I have only been a PN customer for a few months. It initially started out at around 56Mb download. Stats below...

My upload speed is currently 4 below the 'Low' value and my download is has been slowly decreasing as you can see from the graph. My BT IP profile last week was at 54Mb, now I have lost 4Mb.

Does this look like a problem?

To my inexpert eye, it looks as if your line is struggling, particularly on the upload side. I would have expected to see the attenuation roughly the same for upload and download, but upload is around 10dB worse. It might be worth putting in a fault report and getting the line checked, in case there is any degradation, noise, crosstalk or whatnot that is pulling your upload data rate down. Your download rate is within expectations, although only just, and it may be that the poor quality of the upload is causing the download rate to be dropped to compensate.

Unfortunately... It's dropped again...

Now the max achievable is 45?? Actually getting 40 down. Although DSL Checker still says I should be getting:

Featured Products	Downstream Line Rate(Mbps)		Upstream Line Rate(Mbps)		Downstream Range(Mbps)	WBC FTTC Availability Date	WBC SOGEA Availability Date	Left in Jumper

Anyone got any ideas? The router hasn't moved, only been restarted twice in about 2 weeks.

Your connection is definitely in sync lower than we'd expect (46.9Mbps) given the estimates for your line.

Is there any noise on your phone line at all?

I'd suggest going through the troubleshooting steps advised here. However if this doesn't give any improvement, please raise a fault here so we can investigate further.

Thanks Harry, I will go through the steps again tonight when I get home.

Thank you.
