Verify the Wi-Fi router can broadcast an 802.11b/g signal. If using a 802.11n Wi-Fi router, consult the manual/documentation for how to configure the Wi-Fi router for 802.11b/g compatibility.
If you are using multiple WEP keys on your Wi-Fi router, try configuring your Wi-Fi router to use only a single WEP key.
