This error is caused by incorrect internet connection settings, such as network name (SSID), WEP/WPA keys, or any manual settings.
Ensure you have correctly entered basic information such as network name (SSID) and WEP/WPA keys.
Try changing the channel of your wireless router to either channel 1 or channel 11 which can increase download speeds. Be sure to test both channels to see which works better or faster.
