Fibre 38mb drops to 2mb every evening.

[#1]

Hi,

My fibre speed is dropping to, on average, 2/3mb every evening. However in the mornings the speed seems consistent at around 36mb. Is there anything you could suggest as to why this is happening?

Thanks 

Dave

Same here 😡

Is this throughput (as measured by a speed-tester website) or line speed (sync speed) as reported by your router?

[#4]

Ookla speed test

[#5]

take the test here http://speedtest.btwholesale.com/      and do the further diagnostic test too

That's using Ookla speed test. I just don't understand why it would be that unstable.

Its the line speed as per speedtest.net

Not quite sure why this should help? Just tells me what I already know. Here is the results this morning

We need to know your sync speed as well as your throughput. They aren't the same thing.

If you are using a Hub One router, log onto it, go to the Troubleshooting / Helpdesk page and you will see a table of data. Copy and paste lines 6 to 10 here. Mine look like this (you will have different numbers)

6. Data rate:	1999 / 39950
7. Maximum data rate:	25930 / 77729
8. Noise margin:	30.4 / 17.0
9. Line attenuation:	16.8 / 15.1
10. Signal attenuation:	16.2 / 15.1

One possibility is that you are getting airborne interference that is impacting the line, either between the router and the telephone socket or between the socket and the green cabinet in the street. This could affect your throughput without necessarily affecting your sync rate. It could come, for instance, from dimmer switches either in your household or in a neighbour's. That would account for it only happening after dark. But this is only a guess. We need more data.

Doing the further diagnostic test , saves them for BT and PN to check 

if you look at my test you can see 

[#11]

This is the stats this morning, I will post another this evening.

Okay. Good. That tells us that there's nothing wrong with the condition of your line - it's better than mine. You are syncing at 40/2, which is as it should be. If PlusNet test it, they will find nothing. The line is not the problem.

This evening, when you detect the drop in throughput, record the same 5 lines of data (it probably won't have changed) then restart your router, give it time to connect and record the data again.

Meanwhile, see if you can do the ookla pingtest (it's the next tab along from speedtest). You may need to give it various permissions to get the packet loss test to work. Here's what I get:

Do it in the daytime as a baseline, then again in the evening when things are bad.

Here is the results of my ping test this evening. Any solutions?!

Same here Dave ..
