Noticeable slow download speed again this week. limits around 19-50mbps on m350. Is this a physical fault or just bad luck? Seems symptomatic that I'm approaching the end of my contract...

In the last hour it seems to have gone back to advertised speeds, approx 340/350mbps. Weird stuff.

U/S looks broken to me! - Power is too high which could be causing all of these issues!

Hi Atomichobo

Thanks for your post 

I have had a look at the up and downstream from here and we will need to get a Service Technician out 

I have sent you a private message to pass security 
If you can check the purple envelope top right of your screen that would be great 
Regards
