I have a Motorola cable modem and a wired Linksys router. What equipment do I need to buy, to use one of my Ethernet connections to offer a wireless access point? (Or is that only doable with a wireless router?) The former solution would be preferable, since I could place the transmitter in a better (closer) position for the receiver to be used. Essentially, I need a wireless link (possibly part time) between my network and a wireless (Wifi) laptop.
