A customer of mine had sat broadband installed about 15 years ago as the alternative was dialup. When it worked it was ok, but was about as reliable as an old reliant robin. As soon as it rained, snowed or a bird landed on the dish, the speed dropped to a snails pace or the connection dropped completely.
Things may be better nowadays, but I wouldn’t be surprised if the same issues still exist.
As an aside, their neighbour was a scaffolding company called Dick’s Erections which always used to make me chuckle! Yes, I have been drinking this evening, but true story!
