We are on ADSL2 with Plusnet and in the past couple of months have noticed a drop in performance of our internet connection. We used to get 9-10Mbps reliably whereas now we're getting far less than that - single thread downloads run at about 70-120kB/s which is roughly 0.7-1Mbps.
Browsing feels sluggish and streaming doesn't work properly either.
The BT Wholesale speed test site shows 6-8Mbps, but that's more or less the only site that works this fast.
Tellingly, if I start multiple downloads to the same file, each one runs on average around 90Kbps without slowing the others down, until I get to about 10 or 11 downloads which maxes out the connection.
They have sent 4 openreach engineers out and none of them have managed to find any significant problem. They've also increased the SNR and turned on interleaving, neither of which have made much difference.
Now they're basically saying that there's not much else they can do and are trying to encourage me to upgrade to fibre at a discount.
Has anyone ever encountered this before and have any suggestions as to what can be done about it please?
In case anyone wants to read the whole boring story, see my thread on plusnet community.
My speed test result
Thanks in advance for any advice
