I guess this has been posted a 1000 times but my internet connection has recently been slow during the hours between 5pm to 11pm.I live in the Chesterfield area and not aware of any issues as to cause this apart from the obvious heavy traffic.This problem i have had before and spoke to support at BT (which was a nightmare being passed from one advisor to another).
Eventually i had 2 engineers call during the day and they couldnt find a problem with the line.If they came out in the evening they would have seen the issue.I am using HH5 ,is there anything else i can do apart from ring support up.This took 3 months last time from start to finish :((
if you have a HH5 can you go to hub manager then trobleshooting then helpdesk and post 1-12
can you run btspeedtester and when first test completes then run diagnostic test and post results must be done with wired connection btspeedtester
are you using the test socket with a new filter
can you enter your phone number and post results remember to delete number wholesale FTTC check
try quiet line test dial 17070 option 2 should be quiet and best with corded phone
Here are my resultssorry had to take a photo of it from my phone .Used wired connection.
is it possible to run btspeedtster diagnostic test again but during the day to show difference in download speed - peak/off peak
It sounds very much like congestion. BTWholesale should be aware of the situation from their own stats and add extra capacity to the backhaul from your exchange.
