• What Hardware version is your modem? Look at the sticker under modem.
• Link>What Firmware (http://forums.dlink.com/index.php?topic=47512.0) version is currently loaded? Found on the modems web page under status.
• What region are you located?

Router and Wired Configurations
Some things to try: - Log into the routers web page at 192.168.0.1. Use IE, Opera or FF to manage the router. Besure to log into the Admin account on the router.

• Turn off TrueGigaBit Routing (http://forums.dlink.com/index.php?topic=60699.0) under Setup/Internet/Manual for those routers that have this feature for testing.
• Turn off ALL QoS (http://vonage.nmhoy.net/qos.html) or Disable Traffic Shaping (DIR only) GameFuel (DGL only and if ON.) options, Advanced/QoS (http://en.wikipedia.org/wiki/Quality_of_service) or Gamefuel. For the DGL-5500, review this for Streamboost information and settings: Furry's DGL-5500 Review (http://forums.dlink.com/index.php?topic=55136.0)
• Turn off Advanced DNS Services if you have this option under Setup/Internet/Manual or under Setup/PARENTAL CONTROL/Set to>None: Static IP or Obtain Automatically From ISP.
• Enable or Disable Use Unicasting (compatibility for some ISP DHCP Servers) and test under Setup/Internet/Manual. Disable may help with speed performance on higher speed ISP services.
• Turn on or off DNS Relay (http://forums.dlink.com/index.php?topic=45143.0) under Setup/Networking. Link>Finding Faster DNS Addresses using Name Bench (http://forums.dlink.com/index.php?topic=53222.0) and input new DNS addresses under Setup/Internet/Manual.
• Setup DHCP (http://forums.dlink.com/index.php?topic=58017.0) reserved IP addresses for all devices ON the router. Setup/Networking. This ensures each devices gets its own IP address when turned on and connected, eliminates IP address conflicts and helps in troubleshooting and maintain consistency for applications that need to connect as well as mapped drives.
• Ensure devices are set to auto obtain an IP address.

Wireless Configurations
Links>Wireless Installation Considerations (http://forums.dlink.com/index.php?topic=48327.0) and Managing Signal Congestion (http://forums.dlink.com/index.php?topic=53228.0) and Good Neighbour Policy (http://forums.dlink.com/index.php?topic=10634.0)

• Ensure the default (dlink) SSID name is changed. Can be anything and not something that's already in use by any neighbouring WiFi routers. Under Setup/Wireless/Manual.
• What wireless modes are you using?
• Try single mode G or N or mixed G and N?
• Channel Width set for Auto 20/40Mhz or try 20Mhz only.
• Try setting a manual Channel (http://en.wikipedia.org/wiki/Wireless_channels) to a open or unused channel. 1, 6 or 11. 11 for single mode N if the channel is clear. 13 for EU regions.
• What security mode are you using? Preferred security is WPA-Personal. WPA2/AES Only. Some WiFi adapters don't support AES (http://en.wikipedia.org/wiki/Advanced_Encryption_Standard), so you might want to try TPIK (http://en.wikipedia.org/wiki/Temporal_Key_Integrity_Protocol) only or Auto TPIK and AES.
• What wireless devices do you have connected?
• Ensure any devices with WiFi adapter drivers are updated.
• Any 2.4Ghz or 5Ghz cordless house phones or WiFi APs near by that maybe causing interferences?
• Any other WiFi routers in the area that maybe causing interferences? Link> Use a WiFi Scanner (http://forums.dlink.com/index.php?topic=48327.0) to find out. How many?
