Your Downstream figures show that you have a poor signal to noise ratio (RxMER) which is probably affecting the connection. They should be at least 34.5db and preferably more. You can either wait for a Forum Team member to respond to your post, which could take a while, or phone the call centre ... 150 from a VM phone or 0345 454 1111 from any other phone.
Thanks for posting on the community. It's nice to have you here.
Sorry to learn that you are experiencing slow broadband speeds. I know how frustrating this can be.
As Dave_cq mentioned the Modem SNR (signal to noise ratio) for downstream is running low and for this I can arrange for an engineer appointment to check this for you. I've sent you a PM (purple envelope icon, right corner) requesting some details.
There is also a high peak time traffic fault in your area which is causing slow speeds. Our networks team are investigating the problem and are improving bandwidth and performance to help with this issue. The reference number is F004670584 and with a review date of 15th February 2017.
