You can download them by using your Desktop machine that does connect - then by way of a memory stick or even a camera card transfer them to the lappie.
I have to say I spent several visits to a friend trying to sort out a similar problem.
In this case the lappie was simply across the hall in another room.
But the Lappie 'connection [A USB dongle in this case] was close to the powered speaker set.
Thus the magnetic field was possibly shielding the signal.
The Virgin Router though wireless had to 'speak' to a Belkin router placed next to it before the lappie got any joy.
