Every couple of seconds, the internet will suddenly drop in speed significantly for a minute or two. It'll repeatedly do this and I'm unsure what to do. It was fine before Christmas and fine before it suddenly went down for maintenance around 19-21st December kind of time.
Below are the speedtests that I've used, and it's worth noting that it's a student house on the 100mb Package. At the time of the tests, only my Desktop PC was connected.
I'm so sorry that the broadband speeds are dropping so frequently, that definitely shouldn't be happening. I've run a few tests on your connection and it looks like the power levels on your hub are a bit too high at the moment, this could well be causing the issues you're seeing.
I'd like to book an engineer to sort these out for you, I've sent you a PM (purple envelope, top right) so we can arrange a suitable time for an appointment. Get back to me when you've got a minute and I'll go ahead and get something booked in.
