The wireless network drops out intermittently, for no apparent reason. Using the windows XP "Repair" function makes it work again, although a message is generated telling me that the DNS cache cannot be cleared and that I need to contact my System Administrator - I need to have a talk with myself, apparently.
The VOIP side just drops out intermittently also, often in mid-call. To cap it all, it is difficult o know who, in BT, I can turn to for help.
