Some information on this router
http://dlink.com.au/Products.aspx?Se...&Sub2=5&PID=60
Suggest you start with a wired network, unless there is a great distance between router and PC's, that can not be easily cabled. If your not using the wireless disable it.
If you have laptop's check they dont already have built in wireless built in.
For PCI Wireless cards for Desktop Pc's suggest Dlink's DWL-G510 (I like to recommend people use the same manufacturer if possible)

Again you can look at these retail outlets. Note more than likley the stores in the list I linked for the router will be duplicated here as they will carry or can order other dlink gear.
