Sudden upload speed drop

My internet connection has suffered a sudden drop in upload speed, and the SNR margin is showing as 0dB.

Previously I had a fairly consistent 9.22Mb/S until some time between 23:54 30th and 15:53 31st of March when it fell to 7.64.

I don't have a record of the SNR before that date, so I don't know if the download SNR margin has changed. but it is now about 14.4dB.

There is also a gap in my Whitebox stats for the duration of this period, as if the line was disconnected.

 

Any ideas?

Thank you

 

Edit: DSLstats output added. Connected by an Ethernet cable.

(Old date, as that is all I have access to ATM)

Re: Sudden upload speed drop

Hi there, 

 

Diagnostics aren't showing any issues. Have you definitely ruled out WiFi as a potential factor?

Re: Sudden upload speed drop

Hello Adam

Do you mean I should disable all WiFi, in case that is getting into the line?

Re: Sudden upload speed drop

Hi James.

I'd plug a computer or laptop into the router using an ethernet cable.

This will help narrow down where the issue lies.

 

EDIT: I see you're referring to your sync rate coming into the router.

In this case I'd try the steps here.

Hope this helps.

Re: Sudden upload speed drop

Hello Gandalf

I tried that.

Exactly the same, but I'm not surprised, as I have no telephone extension sockets.

I'm wondering if something was changed with all the Openreach activity that has been going on since the FTTC cabinet was installed?
