Which wireless router will work with my skyedge satellite broadband modem?

The properties of my satellite modem are as follows: "Realtek RTL8139 Family PCI Fast Ethernet NIC". I want to use a wireless modem to connect my Nintendo Wii and other PC's to the net. My broadband company will not provide ANY support for more than one connection (I asked them which woud work and their answer was use a wireless router - duh!). I need to know what spec's to look for or if any ADSL router will work, and then if it is as simple as plug & play, or is it a bit trickier?
