^ I agree with Fortuner. Better to go wired.
In addition - if you really want to go wireless, you would still need to purchase additional equipment for the desktops in order for them to 'accommodate' wireless queries/connections. That'll cost way too much as opposed to just sticking it out with a wired connection.
Anyway, there are two desktops and just one laptop so just think of it this way: whatever's two should be given more importance than to whatever's just one
