First two questions that come to mind

1. Are the drivers updated for the wireless card

2. Is there a firmware updated on the Router

Has this problem just accured or is this a new setup

:-)

could also be conflicting with someone elses wireless network...

get her to change the channel on her router and see what happens then.

forgot to say her husband also has a laptop setup the same and his works fine every time

EDIT - just occured

Some times my old pcmcia-card stopped working when i had a excellent connection. I had to remove it and cool it down to get it to work again. Could it be the same issue here? Excellent connection makes it to hot to function? That might be the reason it's not dropping out at work, since it's not that "stressed" there.

this is a built in wifi, would it still do over heat?

is her husband on a N and not a b,g network conx to router?

what brand is the router?

who is there internet provider?

what type of net conx is it?

if she is connecting using b or g then like joanne said other devices in the home will be interfeering i.e wireless home phone, door bells.
