Once the Asus WL-330ge is configured for wireless adapter it is locked into that configuration and must be reset to access the configuration menu.
Follow these steps:
1. While powered on, press and hold reset button (next to power input) for 5 sec or until lights blink.
2. Tell computer to repair network connection or renew IP. (I believe this is under connection properties) Or just reboot computer with device connected.
3. Now you should be able to connect to 192.168.1.220 config menu.
