Networking
• Poor wireless networking performance may be caused by using wireless equipment that is not Designed for Media Center Edition (DfMCE) logo certified. You should replace an older 802.11g only router with a newer DfMCE certified dual-band 802.11g and 802.11a router to ensure compatibility with current gear while providing additional uninterrupted bandwidth for the Media Center Extender. Your Media Center Extender can connect to either 802.11g or 802.11a. Optimal performance can be achieved when your Media Center Extender connects by using 802.11a while other wireless devices, such as portable computers or desktops, connect by using 802.11g.
• Media Center Extender devices connected to the Windows XP Media Center Edition 2005 system through a D-Link DI-784 wireless access point or router with “Dynamic Turbo” mode enabled will cause connection failures. Media Center Extender devices currently do not support “Dynamic Turbo” mode. This mode can be turned off using the D-Link router administration page. Contact the router manufacturer for any additional assistance.
• TV or video may experience frame drop or “choppiness” if proprietary speed boosting modes such as "SuperA”, "SuperG”, or “Turbo” are enabled on the wireless access point. To prevent this issue, disable these proprietary modes on the wireless access point as described in the manufactures documentation.
• Video playback on a Media Center Extender may appear choppy on an 802.11g wireless network if slower 802.11b devices are connected to the same wireless network or if other devices interfere with the signal. These devices could include cordless phones, microwaves, or a nearby neighbor’s 802.11b devices. Try to remove the 802.11b devices from the wireless network or connect the Media Center Extender through wired Ethernet to the network to minimize this effect.
• Media Center Extender devices connected to the Windows XP Media Center Edition 2005 system through a D-link DI-774 wireless router may become disconnected when the user starts TV playback. This is a known issue with earlier versions of the firmware that is used in the DI-774 wireless router. To minimize this issue, contact the router manufacturer for help with downloading and installing the latest firmware revision for the wireless router from the router manufacturer’s Web site.
• If you configure a firewall after you installed a Media Center Extender, the firewall may close ports that the Media Center Extender needs open. This can render the Media Center Extender non-functional. If a firewall is configured before you set up the Media Center Extender, the Media Center Extender Setup program will detect it and help the user with the configuration. If a firewall is configured after setting up Media Center Extender, the user must manually configure their firewall to open the following ports:
• 3776
• 3390
• 5555
• 7777
• You may receive the following error message on the Media Center Extender when you work with earlier network card device drivers:
Network Congestion – There is not enough network bandwidth to provide a good TV experience. For more information, see Help. Would you like to watch TV anyway?
Contact the system manufacture for help with downloading and installing the latest network card driver in the Windows XP Media Center Edition 2005 system to minimize this issue.
