Hi,
My DSL-2730 keeps restarting when wifi is on. The power LED blinks and all connections are disconnected. Thereafter it keeps restarting and does not reconnect. I have to physically switch off the power, leave it for a few minutes and then switch in on and the connections are restored. I have also a PC connected through LAN, but my main usage is through wifi. This is irritating me no end. Has the product reached the eol or can it still be salvaged.

- 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?
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. 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?
- 2.4Ghz Routers only: 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 InSSIDer (http://www.techspot.com/downloads/5936-inssider.html) to find out. How many? Use v3, its free.
- If you have any of these options, Try turning OFF or ON Short GI (http://www.smallnetbuilder.com/wireless/wireless-features/30969-what-do-80211ns-optional-features-mean-for-you), 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.
Router Placement
Forum 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.

I had the exact same issue where all lights of the router would go off and the router would restart immediately. I noticed thia would happen more frequentely when more devices would simultaneously use the wifi connection. I guessed it was an issue with the power supply since the router would just die on multiple wifi connections.
Replacing the power supply fixed the issue. Please ensure the power supply you buy matches the voltage of your existing power supply.
