Test light i setted up my router but the test light keeps flickering i have reseted the seeting but its still the same can someone help me,iv tried everything but nothing seems to work reply back ASAP chhers

Look at the back of the router.
Is there a "RESET" button? If so, push it in, for a few seconds,
to reset the router to "factory" settings (ID of "blank", and password of 'admin').
If no such button, then straighten one end of a Norwegian paper-clip, and push that end into the small hole in the back of the router, until you feel resistance. Then, push it in, and hold it in for 30 seconds, to "reset" the router.

After reseting the router did you noticed that all the lights were flickering. If yes then might be firmawre needs to be updated and for the you have to contact the OEM. If no reset the router once again and wait till all lights flicker.

Are you trying to install the router.
You can do it manually without the CD.

First reset the router for 30 seconds. unplug the power to the router. wait for 5 seconds. Plug it back in.

Make sure that your computer is able to go online through the modem.
If your computer is able to go online through the modem
Then you need to connect the computer to the router ad the modem to the router.
open the set up page of the router and change the settings of the router according to the ISP.

There is one case where everything is fine but still connection drops too often.---
This happens when the network type of your laptop is "public" as ublic networks are less secure, routers usually drop connections after sme time. Change the network type to "private". This should solve your problem. There is one more setting in your router where is says something like "automatically login when disconnected". Selecting this option allows automatically login to ISP when connection is dropped from ISP temporarily.

If network connectivity itself is the problem then you can debug followingly.

Step-1:
If ISP company says everything is fine from their side, then you need to check your router. To confirm this first connect the wall outlet of ISP to your laptop and check network connectivity. If there is problem, then ISP has to fix it.

Step-2:
If connection works fine then ISP is fine and you need to check your router settings. Now check network connectivity by connecting the laptop to the router through a ethernet wire. If the network does not work then your router hardware could be wrong and may need servicing or replacement. If this works fine then go to step-3.

Step-3:
Try resetting your router by using a paperclip. Usually the reset button can be found at the backside of your router. This will reset all the settings and there by making as good as a fresh one. Try to access internet from a place close to router where router signal is strong.
Change authentication and other network settings of your router to connect to ISP. Now network should work fine. Ensure that you set router password to avoid unauthorized access to your router by others.

Unplug everything from it except for the power supply.
Hold the reset button as you did before. After you release and it resets, plug in the Ethernet cable.

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.

try seeting the channel to 11. (adjust the channel)

if your wireless network is secured try to disable it for a while to see if that is causing the problem.

try to reset the device by pushing the reset button for 15 sec at the back
(note: important!! by pressing the reset you will loose the informations that you set on the router be sure to know all the settings before resetting the router.)

try updating the firmware of the router to the latest.

There are two things you can try, however if the router has recieved damage caused by a power surge it is probably cheaper to replace it than repair it if the resets don't work.
You can try a reset by unplugging and leaving unplugged for several minutes.
Check the routers configuration settings (especially if you have a static IP address) as a surge in power may have caused an unintentional reset of the device.
Failing that there should be a small pinhole with an indented button on the back which you can press and hold with a pen or paperclip and cause the router to reset to default settings.
Check the configuration again and make sure it is set up correctly for your network and your ISP
If you are having any trouble checking your configuration please tell me the following:
Static IP ?
Are you able to log into the routers homepage?
Are the lights on the router still behaving normally (turn off and on as devices are connected/disconnected)?
Thanks
Hope that helps

return it to the store where you bought it
its a manufacturer problem
