Ok so this was take just 1 hour after taking the advice of online customer support and factory re-setting my hub.
whilst speaking to them, they assured me there have been no problems at all going to my hub and there has been a stable connection since at least 1st May 2020. This isn’t constant like this but happens for about 15 minutes every hour or so. This test was taken on my phone and I get very similar results on my pc which is connected via Ethernet cable.
clearly there is a problem somewhere but BT are saying everything is fine. Does anyone have any advice on this please
welcome to the BT community forum where customers help customers and only BT employees are the forum mods
in order for the forum members to help please can you post the stats from your router (if hub enter 192.168.1.254 in your browser) and if HH5 then go to troubleshooting then helpdesk and if HH6/SH2 then advanced settings then technical log information .
Have you tried the quiet line test? - dial 17070 option 2 - should hear nothing - best done with a corded phone. if cordless phone you may hear a 'dull hum' which is normal
enter your phone number and post results remember to delete number https://www.broadbandchecker.btwholesale.com/#/ADSL
Someone may then be able to offer help/assistance/suggestions to your problem
Your stats show you have 33/4 mb connection which is well within th expected range for your line and well above the handback of 20mb
you need to run btspeedtester with an Ethernet cable direct to the hub and post results
