DRX-3.4 - Troubleshooting: Network and Wireless LAN

Problems may be solved by simply turning the power on/off or disconnecting/ connecting the power cord, which is easier than working on the connection, setting and operating procedure. Try the simple measures on both the unit and the connected device. If the problem is that the video or audio is not output or the HDMI linked operation does not work, disconnecting/connecting the HDMI cable may solve it. When reconnecting, be careful not to wind the HDMI cable since if wound the HDMI cable may not fit well. After reconnecting, turn off and on the unit and the connected device. 

• The AV receiver contains a microPC for signal processing and control functions. In very rare situations, severe interference, noise from an external source, or static electricity may cause it to lockup. In the unlikely event that this happens, unplug the power cord from the wall outlet, wait at least 5 seconds, and then plug it back in. 
• Our company is not responsible for damages (such as CD rental fees) due to unsuccessful recordings caused by the unit’s malfunction. Before you record important data, make sure that the material will be recorded correctly

Try restarting the unit 

Restarting this unit may solve the problem. After turning the unit to standby mode, press and hold the On/Standby button of the main unit for at least 5 seconds, and then restart the unit. (The settings on this unit are kept.) If the problem persists after restarting the unit, unplug and plug the power cords of this unit and connected devices or HDMI cable.

Resetting the unit (this resets the unit settings to the default) 

If the restart of the unit does not solve the problem, reset the unit, and restore all the settings to the factory default at the time of purchase. This may solve the problem. If the unit is reset, your settings are restored to the default values. Be sure to note down your setting contents before performing the following operations. 

1. While pressing and holding CBL/SAT of the input selector on the main unit with the unit turned on, press the On/Standby button. 
2. "Clear" is displayed on the display, and the unit returns to the standby state. Do not remove the power cord until "Clear" disappears from the display. 
3. To reset the remote controller, while pressing and holding Mode, press the Clear button at least 3 seconds.

Network function

Before you start...

• If you cannot select a network service, start up the network function to select it. It may take approx. one minute to start it up.
• When the NET indicator is blinking, this unit is not properly connected to the home network.
• Unplug and plug the power cords of this unit and the router, or restart the router.
• If the desired router is not displayed in the access point list, it may be set to hide SSID, or the ANY connection may be off. Change the setting and try again.

Cannot access the Internet radio

• In the case the service provider has terminated the service, the network service or contents may not be used on this unit.
• Check if your modem and router are properly connected, and they are both turned on.
• Check if the LAN side port on the router is properly connected to this unit.
• Check if connecting to Internet from other devices is possible. If it is not possible, turn off all devices connected to the network, wait for a while, and then turn on the devices again.
• Depending on ISP, setting the proxy server is required.
• Check if the router and modem you are using are supported by your ISP.

Cannot access the network server

• This unit needs to be connected to the same router as the network server.
• This unit supports the Windows Media® Player 12 network servers, or NASes that support the home network function.
• Windows Media® Player may require some settings. Refer to "Music Server".
• When using a PC, only the music files registered in the library of Windows Media® Player can be played.

Sound is interrupted when playing music files on the network server

• Check if the network server meets the requirements for operation.
• When the PC is serving as the network server, quit application software other than the server software (Windows Media® Player 12, etc.).
• If the PC is downloading or copying large files, the playback sound may be interrupted.

Wireless LAN Network

Before you start...

• Unplug and plug the power cords of this unit and the wireless LAN router, check the power-on status of the wireless LAN router, or restart the wireless LAN router.
  Check the following if the problem persists after you have confirmed the above.

Cannot access wireless LAN network

• The wireless LAN router setting may be switched to Manual. Restore the setting to Auto.
• Try the manual set-up. The connection may succeed.
• When the wireless LAN router is in stealth mode (mode to hide SSID) or when the ANY connection is off, the SSID is not displayed. Change the setting and try again.
• Check if the SSID and encryption settings (WEP, etc.) are correct. Match the network settings with the settings of this unit.
• Connection to an SSID that includes multi-byte characters is not supported. Set the SSID of the wireless LAN router using single-byte alphanumeric characters only, and try again.

Connected to an SSID different from the selected SSID

• Some wireless LAN routers allow you to set multiple SSIDs for one unit. If connecting to such a router using the automatic setting button, you may end up connecting to an SSID different from the SSID you want to connect to. If this occurs, use the connection method requiring you to
  enter a password.

Playback sound is interrupted, or communication is not possible

• You may not receive radio waves due to poor radio wave conditions. Shorten the distance from the wireless LAN router, or remove obstacles to improve visibility, and connect again. Install the unit away from microwave ovens or other access points. It is recommended to install the wireless
  LAN router and the unit in the same room.
• If there is a metallic object near the unit, wireless LAN connection may not be possible because the metal affects the radio wave.
• When other wireless LAN devices are used near the unit, other symptoms may occur, such as interrupted playback and impossible communication. You can avoid those problems by changing the channel of your wireless LAN router. For instructions on changing channels, refer to the instruction manual supplied with your wireless LAN router.
  • There may not be enough bandwidth available in wireless LAN. Use a wired LAN for connection.
