I can well believe that.
We recently tried to take up an internet supply with an independent supplier but, being with Virgin, we don't have a telephone cable connection. Consequently, the supplier arranged for an Openreach 'expert' to come and install a cable.
So far, so good, but the engineer first suggested that the cable be run from an existing pole conveniently at the bottom of our drive to the middle of our house. Unfortunately, as we have a bungalow elevated well above the adjacent road, the cable would pass across our front garden at a height of about seven or eight feet, well within human reach. So that idea was ditched.
My suggestion was to run it to the apex of the highest part of the house, but the engineer assured me that the cable would then have to run down the house wall, through the wall and attached to the main junction box just above floor level in that bedroom. Unfortunately, we'd need this to be at the middle of the house where we want our router to be.
No, not possible. The router would have to be near the main box. Can we just extend the cable from the main junction box across a couple of rooms to where we want the router to be? No, because the signal would then be too weak!
Now, I'm no expert, but if the cable is coming from a pole about 50 feet away, and to that from a cabinet well up the street, would another 20 feet or so make the signal so much weaker?
We cancelled and will have to think again.
