sorry mel..i just skimmed the last few posts.
with a laptop, if her internet service is by cable and she wants to be wireless, then she can use a service like aol for broadband.( it's like $10 a month or something) she just hooks up the wifi router like you got.
that was how it was explained to me by aol.
that is the only reason to use aol if someone has cable internet.
but check with her cable service. they may offer their own router. most do.
