@timsussexmobile You must have been quite distracted replying to a 2017 post made by someone who only posted the once and has never been seen again.
Would I be right to say that you are now outside the cooling-off period as you said it has been a month? Meanwhile you could go to the Think Broadband site and get a BQM (quality logger) setup which will watch the router connection. This is a free service and produces some good evidence of what is happening. Also have a look in your router logs for any critical error. While you're at it can you do a trace route to a couple of well know addresses such as bbc.co.uk and google.com and we may be able to see if it a network routing issue within Vodafone, they have been connecting people in the south via Scotland, and the other way round too.
Are you on FTTC (copper wires to the house) or FTTP (fibre to the house)? Depending on which there may be some differences on where we can look.
