If you have entered the WPA/WEP key for your home wifi network incorrectly, or if you need to change or edit it, you can do this by going into the Network Settings menu and select Set-up WiFi.
The player will now scan for networks. Select to the network that you wish to edit.
Select Yes when prompted to Edit saved Key.
The player will display the current incorrect key. Use the Stop/X button on the front panel to delete any characters and then you can re-enter the wifi network key in the normal fashion.
