Hi Steve,
Thank you for getting back to us.
Having had a look on our systems again today we are still not picking up any issues in terms of speed. Sam knows is showing no disconnections in the last week, and average speeds of 111 download and 10 upload coming into your hub.
There are also still no signal level issues on your upstream or downstream channels.
We are picking up one short term connectivity issue that should be resolved soon, however I have also logged your issues on our systems again. We are also picking up some wifi quality issues within your home.
Apologies if you have been asked to do this before but could you check all of the connections coming into your hub are nice an secure? It may also be worth doing a pinhole reset. (Please be aware this will return your hub to factory settings, and so any personalised settings will be lost, and need to be re-se-up.)
Let us know how you get on! All the best.
Molly
