Once again thank you for your advice hope I am not wasting Mod's valube time.
Some screen shot if they are any help
Forgot to mention brand new RJ 11 Router to socket cable also in place.
Don't worry you are not wasting thier time.
You have a problem and despite your best efforts it hasn't been resolved.
If by any chance it gets resolved before they get back to you then just post here to let them know.
If not just sit back and wait for them to contact you.
Hello fellow oldie.
I have also had a nightmare experience with BT. The customer service and fault fixing is simply not fit for purpose. Check out my post on otInfinity 1 to Infinity 2 issues.
Part of my experience involved exactly what you have had when picking up the phone.
It is a common problem according to the engineer that I had visit me. Basically when you pick up the phone it sends a surge of current down the line (very small) which in turn creates a noise on the line situation which is enough to screw up your hub connect and disconnects you for a short time.
Bad news is there is now easy cure given the complex and in many cases the dated infrastructure (copper wiring) that Infinity has to use.
Just keep hassling them ask for your complaint to be escalated and given a case handler, then at least you will have a direct line of contact with a human.
Very worrying state of affairs I hope that a resolution is swiftly administered to your account.
It seems the Smart Hub is not as Smart as they think it is!
I have a limited knowledge of fault finding but I have isolated as much as I can with just the phone and Smart Hub connected to the test socket via a brand new plug in filter and brand new RJ 11 connection cable. I have even run the setup for most of today without the phone plugged in just the Smart Hub plugged into the filter which made no difference. My inclination is to a fault being with the Smart Hub, although it is wisperd by some engineers that the cabling in my area is poor.
I did get a call regarding my complaint which I missed but the voice on the answer machine reassuringly told me they would ring back later, yes your right BT again did not keep to their word they did not call back. BT's integrity is being shredded by the hour.
Once again thank you for your insight, I know that the vast majority of the members and all the mods do their utmost to provide the best of help they can which is much appreciated it is a pity BT and Openreach cannot follow their example.
Thank you for letting me know.
Partial resoluton the speed has come up again 24m through put, Downstream sync speed: 27.40 Mbps
Upstream sync speed: 7.20 Mbps still not back to previous levels but I presume there will be another 10 day settling in period.
Just need to sort out the outstanding complaint.
Noticed that the firmware update date has changed from 29/08/2017 to today's date 17/09/2017but the version number remains at SG4B1000B316 so has the first update become corruptedin some way not so Smart hub.
