- Ensure the default (dlink) SSID name is changed. Can be anything and not something that's already in use by any neighboring WiFi routers. Under Setup/Wireless/Manual.
- What wireless modes are you using?
- 2.4Ghz Routers only: Try single mode N or mixed G and N?
- Channel Width set for Auto 20/40Mhz.
- Try setting a manual Channel to a open or unused channel. 1, 6 or 11. 11 for single mode N if the channel is clear.
- 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.
- What wireless devices do you have connected?
- Any 2.4Ghz or 5Ghz cordless house phones or WiFi APs near by?
- Any other WiFi routers in the area? Link> Use InSSIDer to find out. How many?
- If you have any of these options, Try turning OFF 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.
