Modem light won't stop blinking/No connection
Hey everyone. I am having a serious problem with my wired internet connection. I have a wired connection and a wireless connection. My wireless connection works, and my wired one doesn't.

What happened was that I went to unplug and replug the wires from my router (long story) and now the router must not be working right because I can't access the internet on my wired connection. To restate, my wireless connection works.

I checked to see if I plugged the wires from the router in the wrong holes but I didn't (I think). Remember, ever since I unplugged and replugged the wires from the router, this wired connection screwed up.

Below is a picture of the router I have. The one in the yellow circle (labeled as modem) keeps blinking. What can I do to fix this? Would greatly appreciate it!

Check the wiring.

The modem should be plugged into the WAN/Internet connection, and the computer(s) should be plugged into the LAN/Network connections. Note that the WAN/Internet jack should be uniquely identified.

For future reference, the picture of the devices gives us very little info. Best is the exact make, model, and hardware version of each device, modem and router.

Let's see this from the working computer.

Hold the Windows key and press R, then type CMD to open a command prompt:

In the command prompt window that opens, type type the following command:

Note that there is a space before the /ALL, but there is NOT a space after the / in the following command.


Right click in the command window and choose Select All, then hit Enter to copy the contents to the clipboard.
Paste the results in a message here.

If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.

FWIW on both my Belkin routers that jack is labeled "to modem."
