Hi @drwarrowsmith, thanks for getting in touch and I'm sorry to hear you're having connection issues as of recent. I can confirm when checking your connection from this side currently we can see there's an underlying fault currently being detected with your connection however the fault location of which isn't clear. In which case, please can you run through the below internal checks your side to see if the same issues you've been seeing look to persist.
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 faceplate of your master socket and seeing if the speed issues and drops in connection look to 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:

Please let us know how it goes and I'd advise whilst we're detecting an underlying issue with the connection to please run wired speed tests if you're not already as this will help rule out the possibility of underlying wireless issues also. By all means if there are wireless issues present after the underlying fault has been resolved then we'll happily help address them.
I look forwards to hearing from you further.
