Hello John.
The new set top box has not arrived yet, and the engineer who came on Saturday to change the Router knew nothing about it. I'm beginning to wonder if it was ever ordered for me. The Engineer came on Saturday afternoon to change the Router for an upgraded one for the Fibre land line. This , he thought, would be a 40 minute job. However, he actually spent over 2 + 1/2 hours with us as he was unable to link up, and get authorisation for the new Router on my account. He eventually gave up with that one, after sending numerous messages to the administrator. He then tried another Router, and after some time, was successful in setting that one up. We then learned that although we could use our old analogue phone in another room, it would not ring as the new line does not have any electrical power. That was never explained to us at all. Luckily we have other land line phones.
At present, my computer is running fine as I have an ethernet cable connection through to the Router. However, My Wife's laptop will not connect via Wi Fi, and our Alexa will not connect at all, even though the whole system has TWICE been switched off and on.
Any advice would be appreciated.
