Speed issues

Hi,
BT completed some cable work to my house last Wednesday, as they connected the new cables as you would expect my Fibre went off line for 15 minutes. After the internet came back online I did a speed test and my speed had gone from 77mbps to 55mbps. I logged an issue with Plusnet who then acknowledged that there was a problem with the line. 4 days later Plusnet update the post and tell me that there is nothing wrong with the line !!! Having completed a BT wholesale speed test I can clearly see that my IP profile is not correct, normally it would be 77mbps however, it's currently 60 mbps. Over the years I've had a similar issue twice, on both occasions the cause has been a 'stuck profile'. Plusnet are now telling me it's an issue with my wi-fi !!!
Please can this be reolsved ?

You will need to give it some time for the DLM to increase your profile.
My profile was lowered when I was disconnecting my modem several times during setup. After waiting 3 weeks the profile went up to 72.46Mbps. This was last week.
I am still waiting for it to go back to 77Mbps. Just have to be patient for this process.
In the meantime, you should ask for a GEA test on your line.

Hi @robquick, thanks for your post.
It does indeed look like the exchange had clamped down on the speed profile due to the instability caused by the engineering works.
We've changed this setting now and a quick reboot of the router should get you back up to speed.
Please let us know how you get on.

Hi,
Thanks, I have followed your instructions and the speed has improved however, it's still down by about 20%. Looking at my profile it's moved to 70mbps but not the normal 80mbps. Again, this is exactly what has previously happened on two occasions, both times it's been caused by a stuck profile..............please can this solution be reviewed and potentially resolved ?
I've attached my BT wholesale test which clearly shows my IP profile at 70mbps.
Thanks.

Hi @robquick, thanks for your post.
I can see from the account that it does look like the profile had become stuck, which is something we can sometimes see when a Static IP is in use.
I've had the relevant changes made and you should notice those speeds go back up within the next few hours.
We're sorry for any inconvenience caused but please do let us know if you need anything else at all.

Many thanks.
Nothing has changed yet, as you say I will try again in a couple of hours. Will I need to reset the modem and router ?
Thanks.

Hi @robquick, if it still hasn't improved, reset the router and let us know if there is still an issue.

I've now rebooted my modem and router and my speed has again improved. However, my upload and download speeds are again still slower then they were prior to BT replacing various overhead cables in my road. Surely, with new cabling my speeds should be equal or better than they were before.........not worse. Again, my IP profile is still lower than it was before suggesting this is the cause ? Can this please be reviewed again, and fixed once and for all ?
Thanks.

Hi,
Looking on BT wholesale my speeds are still around 10%-15% slower then they were prior to BT replacing various overhead cables in my road. Surely, with new cabling my speeds should be equal or better than they were before.........not worse. Again, my IP profile is still lower than it was before suggesting this is the cause ? Can this please be reviewed again, and fixed once and for all ? Previously this has ALWAYS been caused by a stuck Profile.
Surely if my IP profile is lower than before my speeds will be lower too ?
Thanks.

Hi @robquick, thanks for your post.
We can see that the IP Profile is currently at 76.3mbps, which is within the estimates for your line.
Due to this, there isn't a great deal that we're able to do in relation to your speeds.
We're sorry for any inconvenience caused.

Hi,
With respect that's not a helpful reply.
My speed is 15% lower than it was before Openreach decided to replace the overhead lines (albeit everything was fine prior to this). My IP profile is also lower than it has been for the last 5 years I've been with Plusnet............but because my speeds are 'within the estimates for my line'...........there's not a great deal you can do ??!!
Surely based on the fact that my speed and profile is lower than before this would suggest that there is an issue somewhere ?
Thanks.

One thing that jumps out however is that the connection has been dropping a fair bit over the last few days looking at the graph below:
I'd advise from here then although as you mentioned work has been carried out outside which may be behind the drops and slight dip in speed to run through a few own domain checks before we raise a fault and more than likely get a engineer out to investigate further given nothing fault wise is flagging up our side.
I'd recommend starting with basic checks here: http://goo.gl/p2tpvL
And if that doesn't help the next thing would be to rule your internal wiring out by plugging the connection into your test socket which is under the face plate of your master socket and seeing if the drops stop. 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
(Given the frequency of the drops I'd recommend staying in the set up for 24-48 hours to see if the issues persist)
Let us know how it goes

Hi,
I've completed the below checks and I'm still in the same situation.
Can someone please answer one simple question ? Why is my IP profile lower than it's ever been ? If this is lower than it should be would that not suggest that's the issue with my speed ?
No one seems to want to answer that question !
Thanks.

Your IP profile is 96.7% of your downstream sync speed so if your sync speed drops then your profile will drop as well.
There are numerous reasons why your sync speed may have dropped but the most common one is crosstalk which is interference from other lines.
Whilst I appreciate any drop in speed is frustrating I'm afraid that there isn't anything we can do
