To be honest, now Orange is a nightmare! Have a look :

I have been lost connection for totally 3 months and they are still trying to find some excuses to delay my connection. Have got 2 line tests and a million of times of call, but still got no broadband at all and eventually I am paying for just nothing.
You got to think about their CS hotline, it's not free!
In average, you have to spend to 2mins to speak an advicer and another 5 mins to play around with their default checking process for your live box. Eventually, you might end up paying a call of 30 mins for no solution at all (they might say there will be a line test on your line, but you never know if this happens)
