Welcome!- What region are you located?
- Was a Factory Reset performed before and after any firmware updates then set up from scratch?

>FW Update ProcessRouter and Wired ConfigurationsSome 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.- Setup DHCP 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.
- If IPv6 is an option on the router, select Local Connection Only under Setup/IPv6.
- Set Firewall settings to Endpoint Independent for TCP and UDP under Advanced/Firewall. Enable or Disable SPI to test.
- Enable uPnP and Multi-cast Streaming under Advanced/Networking. Disable uPnP for testing Port Forwarding rules. Enable IPv6 Multi-cast Streaming for routers that have a Media Server option. Disable IPv6 Multi-cast Streaming if IPv6 or Media Server is not being used.

Wireless Installation Considerations and
Managing Signal Congestion and
Good Neighbour Policy - Ensure the default (dlink) SSID name is changed. Ensure that different SSID names are used between each WiFi 2.4/5Ghz radios. 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 N or AC on 5Ghz?[/li]
[li]Try setting a manual
Channel to a open or unused channel. Try channel 48 or 149 on 5Ghz.[/li]
[li]What security mode are you using? Preferred security is WPA-Personal. WPA2/AES Only. Some WiFi adapters don't support
AES, so you might want to try
TPIK only or Auto TPIK and AES. [/li]
[li]Any 2.4Ghz or 5Ghz cordless house phones or WiFi APs near by that maybe causing interferences?[/li]
[li]Any other WiFi routers in the area that maybe causing interferences? Link> Use
InSSIDer to find out.
How many? Use v3, its free.[/li]
[li]If you have any of these options, Try turning OFF or ON
Short GI, WLAN Partition, Extra Wireless Protection and
HT 20/40 Co-existence if you have it. Also testing with HT20/40Mhz Co-existence enabled will impact results as well. I prefer to use this option OFF. Recommended settings are default. Under Advanced/Advanced Wireless. [/li][/list]
Router PlacementForum User - "Well I feel really dumb. After moving the router away from other electronic devices my speeds are back to normal. Just a heads up for anyone experiencing slow speeds, you might want to move it away from other electronics and see if that helps."
3-6' feet minimum safe distance between devices.
Placement on main level floor and central in the building and WELL ventilated is preferred. Not in basements or closets as building materials, or near by electronics devices could interfere or hinder good signal propagation.
