I am posting this, as it might be helpful to others with wifi problems.
I have Dell Inspiron 14z running windows 8.
The wifi would get disconnected, and 'solve problem' would reset modem, and reestablish the connection, but most of the time would also report 'a wire is loose or disconnected'. wifi got disconnected once or more often in the day. Occasionally a day would go without wifi disconnect.
Finally Dell agreed with me that the modem must be defective, and they replaced it five days ago. since then wifi has not got disconnected.
So it turned out to be a defective modem.
