DI624 will not work. All 4 LAN lights permanantly on with no cables connected

SOURCE: LAN led light alway on and flashing

Reset the router:
While the router is powered on press and hold the reset button for 5-10 sec. Release the button and wait until the router boots up (1 min).

If this does not work then you can try this

Try setting it into recovery mode and loading firmware:

Unplug power cable from the router and press the reset button. While holding the reset button plug the power cable in. Continue holding the reset button untill you will see LEDs on the router flashing rapidly.

You should be able to log into the router - you will see a prompt to load firmware. The firmware is available on our WEB site: http://www.dlink.com.au/tech/

Note - suggest you d/l the firmware BEFORE you reset router

I think that u need to go on, open your internet explorer, and enter your ip address in the address bar. Enter your password. Check your settings. Sometimes, internet stops, because firmware needs to be updated, sometimes its your computers driver (this is not likely); but most likely, your best option is to update the firmware for it. Consult your manual or internet on how to do it.

Try resetting the router . Press the reset button for 10 seconds and after 10 seconds unplug the power cable but continue pressing the reset button for another 30 seconds after 30 seconds plug in back the power cable and continue pressing the reset button for 10 seconds and release it after 10 seconds.

try to open an Internet browser and type in 192.168.0.1 on the address bar. It should give you the DLink page. Once you have that configure your connection.

please call dlink tech support at 877-453-5465. just an advise on how to handle the call when you reach dlink tech support (agent); do not agree to call back after you troubleshoot with them (they'll be giving you a case id reference# and be advising you to check your pc or call "who" and call them back to continue the troubleshooting). insist to the agent that he need to resolve the problem asap (by the way, agents are not allowed to drop the call or they'll be dead-history!). and if the agent still insisted you to call back, ask for a "senior level technician" to finish the job (escalate the problem).
fyi: dlink tech support handling time to resolve a call is 15 to 18 minutes only. if you reach that 15-18 minutes (max) time the agent will think of a way for you to call back (advising you to check with your pc manufacturer, check with your ISP, call microsoft to update your software, etc... non-sense!) they need to do this in order to reach their handling time (agents need to reach 21 to 25 billable calls, and billable calls are "solution provided", "resolved", and "dropped call"). ---- believe me, i was one of them and repented.

You could pay a qualified technician $50 for one hour of "trouble-shooting",
and then be told that it's not fixable,
or you could skip that step, and just pay $50 to buy a replacement.

Contact D-Link; if the device is still under warranty, they will replace it, at minimal cost to you.
