I've got my desktops on an ethernet network, and am buying a laptop for my daughter. I don't want to convert the desktops to wireless, but was wondering if I can tie a wireless router into my cable router for just the laptop. I want her to be able to share files and access the internet. Worst case, I'll add a few ethernet points around the house, but I'd rather give her the option to take it anywhere in the house and not trip over a cable, if it's possible. Thanks in advance!
