Thank you to everyone who has contributed … it seems that there are quite a few avoidance suggestions, but recommendations difficult to find - not unusual in the telecoms market anywhere perhaps.
As we are in remotest Gers, we already have a rugby pitch size sat dish, but it consequently doesn’t like wind gusts much, so we have already discounted that for internet. Also, I have a 4G router that I could use, but unfortunately it isn’t actually any use in remote areas as there isn’t a regular signal of any G (let alone 4) anywhere near us!
The problem I find with the main providers is that they seem to want to supply everything including useless (in our case) TV, plus landline, and the kitchen sink etc. All we want is the internet side of the wire. I even have the VOIP modem already as I purchased that three years ago.
The other silly thing is that fibre cable was installed along our nearest small ‘main’ D road linking local towns less than 1km away several years ago, but linking in our little hamlet … !
