Welcome to the forum and sorry to hear you're getting lag. I've tried to check your connection to see what could be causing this but was unable to locate your account. I've just sent you a private message requesting some information so that I can investigate further. To view your messages just click the envelope at the top of the page.
I've now checked your connection and there is currently a SNR fault in the area which will cause drop outs and speed fluctuations. This is under ticket F004401664 and is due to close 05/05/16. Once the fault has cleared we can check the connection again for you.
