When you do move it might be worth seeing how near your cabinet is before deciding between adsl or fibre
Thanks for the advice B13blues. I'll keep that in mind. At present the cabinet is just outside this block of flats, but I've never had the advertised download speeds, so there's no point paying extra for fibre after the move. I'm used to this now, and I'm not downloading as much as I was a while ago.
I just wanted to let NeilO know things have finally been put right. A very well-mannered young (Scandinavian?) man has now properly attached both extensions to the walls.
Problem solved. Thanks to NeilO and all concerned.
