When initially powered on all indicators except W Lan lights up. Is this normal? Router is WR841ND

Welcome to FixYa
Indication of Router Lights:

• Power light blinks. If LAN or WAN cable is plugged in, their respective lights will flash on activity.
• Power light turns off for several seconds.
• All lights, except power light, turn on and then off.
• Power light blinks slowly, then faster, and WLAN light will turn on.
• Once Power light and WLAN light are on solid, the router is fully rebooted.

A working router should show solid green power light. upgrade the firmware of the router.

Hi,

It seems that you need to reconfiguer router
please follow steps to reconfigure router

RESET THE ROUTER :
1. At the rear panel of the router, near the antenna, there is a very small round pinhole that contains the reset button.
2. Using a pen/pencil/paper clip, hold the reset button for 60 sec. so that the test light starts flashing.
3. After few seconds when the test light stops flashing Power cycle the unit.

1. Please remove all the connections from the router. Connect power to the router and then connect a cable from the computer into any of the 4 lan ports on the router. Make sure the modem should not be connected to the router or to the computer.
2. Open up the Internet Browser (Safari, Internet Explorer, Mozilla Firefox, Opera, etc.).
3. Put http://www.routerlogin.com/basicsetting.htm in address bar.
4. On the basic setting page scroll to the bottom and click on Apply.
5.Login to the router (Username = admin Password = Password)
6. Click on lan ip setup under advance.
7. Change the lan ip to 192.168.10.1 and under use router as a dhcp server change the starting ip as 192.168.10.2 and ending ip as 192.168.10.51, click apply and click ok for any popup message that arise.
8. Once the browser display some error message like CANNOT FIND SERVER, ACTION CANCELLED etc, Connect the dsl modem on the wan port of the router and restart the computer.
9. Power off the dsl modem and the router after making the connections.
10. Power on the dsl modem and wait till the dsl light comes on, then power on the router.
11. Open a web browser (Internet Explorer, Mozilla Firefox or Safari).
12. Access the router (http://192.168.10.1).
13. Login to the router (Username = admin Password = Password).
14. Click on Setup Wizard and then select "Yes" and Click "Next" on the detection window.
15. It should give you a "Dynamic IP Detected" or "pppoe detected"(type the Username & Password of your dsl account in case of pppoe detection) and then click next.
16. click Apply.
17. Open up another browser window and try to access internet.

hope it will resolved your issue

It's dead, sorry. You could TRY removing the power cord, holding in the reset button and powering it back up with the button HELD DOWN for at least 10 seconds. That will factory default it, so I hope you know how to program it all again! (please don't contact me and complain if you don't...)

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.

On the bottom of the Modem, it usually lists the type of voltage/current ratio, for example, My modem is a 12VDC in, output is .75A Through the modem. Each modem has its own power requirements. Therefore if they dont match, you have the chance of either underpower (which means no use) or overpowering (and killing your modem permanently)

Best suggestion si the same as above by cnavarro, Buy the Right power supply for it, dont just try anything. get the matching one. Otherwise it will be Incident A or Incident B. Neither would work well, and you would end up buying a new modem all together.

If you have cable internet then you need to :
* disconnect router from cable modem
* restart the cable modem (power off-on)
* restart the router (power off-on)
* connect cable modem to router WAN port using CAT5 straight cable

If problem still exist try changing the cable to new one. If it still does not work then contact your ISP

try to use another power adapter with the similar power output aside from what came with your 2wire modem if you have one, if it works fine that means the original power adapter is busted and i think it is also covered by the warranty, get a replacement from the store where you purchased it.

oh by the way, it's normal for all of the lights on your modem or router to blink when you initially power on the hardware, usually your hardware will perform a system check for several seconds to verify if there is any problem after that, several lights if not one should remain steady like the power light, the other lights on the other hand like the ethernet(LAN) or the wireless(WLAN) will most likely flicker from now and then because it indicates activity between the modem and the device/s attach to it.

Hope that answer your concern about your 2wire modem.

the web page of your router cannot be changed by the isp, but what may have changed is your network cards ip address, as thats the only wat the router cannot be reached if you are on a different address route, so check that your card is 192.168.0.X, the last being different to the router. the only other way this may have happened is if you have used an installation disc and it has changed all address so that they are different to what the routers manufactured address is and therefore cannot be altered but is allowing a static ip address or mac addresses for internet connection. The outer may have simply froze out, and you may have to reset the router by way of a pin hole button at the rear of the unit or underneath or firstly try a restart by unplugging it.

Arunk, When you say the electrical characteristics of the new A/C adaptor are the same as the old one did you check to ensure the amperage and the polarity of the power plug is the same as well?
