Renewal of contract and speed has fallen through the floor

[#1]

My renewed contract for unlimited fibre started yesterday and my connection speed has dropped by approx 10mbs despite the promised speed. Instead of my previous download speed of approx 36mbs I am now getting only 26mbs. Upload speed is similar to previous. I have gone through troubleshooters without improvement and am now doubting my router. Can line be checked?

Hi @janeandtony and welcome to the Community Forums!
I'm sorry to see you're seeing speed issues as of recent.

Checking into your conenctio nfrom this side we can see 28.7Mbps donwload and 6.3Mbps upload getting to the router which is below the 34-40 estimates we have for your line.

Looking at the conenction testing results above there does look to be high retransmission currently enabled on the line which could explain the lower sync speeds seeing however this error preventing line setting will only have been turned on if there were errors and interference on the conenction.

I'd advise moving forwards then to set your router upo within the test socket for 48-72 hours and monitor to see if the speed increases and if the high retransmission is removed. This can be done by plugging the connection into your test socket which is under the faceplate of your master socket. This rules out internal wiring, face plates and extension sockets as being the cause. How to locate the test socket and set your connection into it can be found here:
https://community.plus.net/t5/Library/Testing-From-The-Master-Socket/ba-p/1322242

Let us know if there's any improvement in this set-up over the next few days and if not we'll happily raise a fault with our suppleirs to investigate further.

Many thanks for confirming speed has slowed up and advising removing face plate of master socket.

However, my BT Open Reach Mk 3 has different face plate and if I remove it, it does not enable connnection of both telephone and router plugs simultaneously, and I cannot be without landline for 48-72hrs. Unless I use an old "splitter" that I have, and would this complicate the diagnosis? Also, I dont currently use the ADSL filters, as I believe these are not necessary with fibre.

Hi Tony

Also, I dont currently use the ADSL filters, as I believe these are not necessary with fibre.

Yes it needs to be one of those (aka microfilter)

If you don't have one, could you ask a neighbour, just for a few days?

If that's not practical, then @BD will hopefully drop one in the post (though being a weekend, plus the 3-5 day wait will delay this). Having said that, it's not uncommon for one to arrive earlier.

@BD 

If the download range is allegedly 34-40 Mbps then presumably the 32.4Mbps profile isn't helping either. Can't that be removed now or does this happen automatically if the high retransmission mode is disabled?

[#6]

I have removed face plate from my BT Open Reach Mk 3 master socket and inserted ADSL/phone splitter/filter with router and phone lines connected. Speed not good yet but assume it needs up to 72 hours to settle down.

Hi @janeandtony I've re-tested your line today and I can see that your speeds haven't improved. With this in mind we are going to need an engineer to look into things further.

I've got your availability request and the appointment for an engineer has been booked for between 8am and 1pm on Tuesday, the 16th of April 2019.

Please let us know if this needs rearranging. I've also updated your fault ticket here.

@Baldrick1 the profile being at 32.4 isn't really indicative of anything. The time stamp from there was also April 1st. The sync speed is the bit that's under performing. The profile should bring itself back into line when the sync improves.
