I have iBall 150M Extreme Wireless N Router. I am trying to connect my internet through this router. I configured it correctly (using quick configuration) as per my knowledge using static IP Address. But When I plugged in WAN cable in to WAN (Blue) Port. It is not showing me LED ON for WAN on Router.

I Said I configured it correctly because it worked for me once and then when I switched off my modem and router then it never worked.

I plugged same cable in to my Laptop and it is working perfectly. Also, I tried with 2 routers (both are same make and model).

I am connected with modem.

In Router configuration page, it shows me WAN Port unplugged when I try to Auto Detect IP Address.

Any one faced this kind of issue ? Please let me know. Thanks in advance.

This question came from our site for system and network administrators.

Just wondering did you find the solution to the problem. – user88311 Jun 26 '13 at 17:07
Is your ISP-provided modem just a modem, or is it a modem/router all-in-one? ISPs tend to send out combination modem/routers as these offer the ability for SoHo environments to quickly connect multiple devices so they can access the Internet immediately. If your modem is a modem/router and you're connecting another router to this then this is where your problems begin... double NAT'ing etc... – Big Chris Jul 14 '15 at 14:42

Sounds like maybe a short in your router, if you got it from your ISP or just bought it recently I'd return and get a new one just to see if that solves that problem.

This could be 1 of 2 things to the best of my knowledge.

  1. Your power cable can be shorting out your WAN port causing you to show no network connection. I have had this problem happen to me in the past, and when I changed the power cable, my router lit up like normal and gave me a connection without anymore problems

    1. Your WAN port is blown/fried and is no longer functioning. This sounds like a higher possibility, especially on a fairly old router. Unfortunately, there isn't much that you can do about this. You can go ahead and try a hard-reset. Or, if you are daring, you can take the casing off the router and inspect it to see if there is any physical damage.

Hopefully option 1 fixes the problem, but if not, it is time to move on and purchase a new one (unless it's still under warranty or from your ISP)

Check the pins in the jack where you plug your ethernet cables in. Sometimes these pins can get bent backwards or sideways, preventing a proper connection. The image below shows the pins I am talking about. If they arent straight take some tweezers, or small needle nose pliers and gently straighten them out.
