Well if it has been repaired at the ISP end, then your problem is likely in all the settings they tried to get you to change locally. Your problem now is finding out if in fact BT has fixed it, before bothering to try fixing your settings, becuase if they havent then nothinsg gonna solve it anyway frown,

And of course thats the RUB isnt it, a company blames the user, the user adjusts settings and then when it is fixed the user still cant connect due to settings changed.
