Peak Time slowdown

As I can't get through on chat at the moment and can't speak at the moment  I'm resorting to the forums in the hope that one of the nice members of staff can raise a ticket on my behalf.


I'm having some issues with peak time performance.


The internet is fine during the day but in the evening the performance can be diabolical and there doesn't seem to be any logic, for example:

6:38PM - 8.64 Mbps.

6:40PM - 37 Mbps.

6:41PM - 10.93 Mbps




Sync speed is OK and there doesn't appear to be anything wrong with the line at the moment so I'm wondering if it's congestion and if anything can be done.

Re: Peak Time slowdown

Hi @Nom_D_Plume,

I'm sorry to hear you're having intermittent speed issues and have had trouble trying to get through to our webchat.
We're more than happy to look into any issues you are having via these Community Forums and my findings after looking into your connection are below:

Test Outcome Pass
Test Outcome Code GTC_FTTC_SERVICE_0000
Description GEA service test completed and no fault found .
Main Fault Location OK
Sync Status In Sync
Downstream Speed 40.0 Mbps
Upstream Speed 10.0 Mbps
Appointment Required N
Fault Report Advised N
NTE Power Status PowerOn
Voice Line Test Result Pass
Bridge Tap Not Detected
Radio Frequency Ingress Not Detected
Repetitive Electrical Impulse Noise Not Detected
Cross Talk Not Detected
Estimated Line Length In Metres 444.1

Parameters Last Traffic Count(Upto 15 mins) Current Traffic Count(Upto 15 mins)
Start Time Stamp 2018-11-09T13:42:16Z 2018-11-09T13:57:16Z
Ingress Code Violation 0 0
Egress Code Violation 0 0
Errored Seconds 0 0
Severely Errored Seconds 0 0
Unavailable Seconds 0 0

Everything in terms of testing is looking fine with the sync speed with no signs of errors or issues.
I've also tested for congestion and overheating of equipment however that's coming through all clear also:

Date HOT VLAN(Yes/No) Action Fix Date
09-11-2018 NO    
08-11-2018 NO    
07-11-2018 NO    
06-11-2018 NO    
05-11-2018 NO    
04-11-2018 NO    
03-11-2018 NO  

Can I ask then, are you seeing these intermittent speeds over solely wireless devices or wired also? As it could be wireless interference behind the intermittent speed you're seeing and if so we can advise on how best to optimise your wireless settings to suite the property.
Have you noticed the intermittent speeds across more than 1 device? And when testing the speeds was there anything running in the background? Streaming/downloading etc...?

We look forwards to your reply so we can investigate this issue further.

Re: Peak Time slowdown

Hi Ben,


Thanks for the test results. 


Testing was done with an Ethernet connection direct into the router with no other downloads running. Slow downs have been noticed on multiple devices.



The slow downs seem to happen between 15:00 and 19:00 (roughly) I was wondering if it was when the kids got out of school hence why I thought it might be congestion. Outside of these times the connection is spot on.


Any chance it's weather related? We've had problems with moisture in the lines before but I'd expect that to show up as errors in the line and be all day rather than at peak times.


With respect to your offer regarding wireless connectivity, I'll take any advice you have on this to rule it out. (It's an old stone property so optimisation hints welcomed).


Thanks for the help.

Re: Peak Time slowdown

Hi @Nom_D_Plume,

Please run a speed test via an Ethernet cable and Internet Explorer / Microsoft Edge. If the speed is lower than the estimated speed during the times mentioned, please click further diagnostics then enter your telephone number and run the diagnostics to send this information to us.

Along side this, please raise a fault and let us know when you have completed it.

Usually when the service has been effected by weather conditions we would see a drop in sync speed but after all our testing the sync speed has been at 40Mbps.

As you have run speed tests when connected via Ethernet there is no reason to believe it is a wireless connectivity issue however, if you would like to see how to improve wireless connectivity I have crated a ticket on your account.

Thank you.

Re: Peak Time slowdown


Thanks for the information.


Running the BT Wholesale test gives me 39 Mbps which is what you'd expect but the ookla speedtest gives 21.



So it's possible that I'm experiencing congestion but not on the PlusNet network so it's out of scope.


I'll keep the information you've given me and if I get problems at peak times next week and the bt tests don't work I'll raise a fault as suggested.

Thanks for all the assistance.
