The short answer is no you don't need another adpater...
You need a wireless router device of some flavor. The
Linksys WRT-54G series get good reviews for example...
I recommend staying away from the so called Pre-N devices and stick with routers that do
802.11g. Make sure the router will also support
WPA2 or
WPA encryption. WEP encryption is very weak and not safe.
