I decided on the WUSB54G because I did not have any available internal slots.
Look for reviews on all these items posted separately. For this review, I'll be discussing at the WUSB54G.
For my initial conversions, I was converting a desktop PC and an older laptop. When it came time to make the jump to wireless, the WAP54G seemed the logical choice, as I would not have to reconfigure anything on my existing network. Already part of this network is a Linksys single port Cable / DSL Router. I have a SOHO that uses a wired 10/100 switched network.

And your wireless communications can be protected by industrial-strength Wi-Fi Protected Access (WPA) encryption, so your data stays safe. The Wireless-G USB Network Adapter is also compatible with the Wireless-B (802.11b) network standard, with data rates up to 11Mbps. The included Setup Wizard walks you through configuring the Adapter to your wireless network settings, step by step. (It's compatible with both USB 1.1 and 2.0 ports, but 2.0 will yield the fastest speeds.) It gets its power through the USB connection, so no power cord is necessary. To install, simply plug the Adapter into any available USB port.
