Router Doesn't Recognize Modem

by Cg2916 / July 23, 2011 8:09 AM PDT

When I plug my computer directly from the modem to the computer, it works fine. But when I plug the modem into the router, the router's modem light flashes orange (i.e. error).

Could be proper. So little to work with.

Try the usual method.

1. Turn the power off to the modem.
2. Move the cable from one thing to another.
3. Power up the modem then the next thing giving the modem enough time to start up.

Already done that. It's what I do by default.

You may have to call the service and ask for a reset.

The most common issue is usually covered by those steps but given so little to work with, there's not else to offer.

It's not the service. Like I said, Modem to Computer is Fine, Modem to Router is not.

Sorry for the typo.

Given no details of make, model, firmware, settings we are left with little but to guess (badly) or suggest you call for service and support.

Firmware Shouldn't Matter

I plugged in a second router. The second router works for wired computers, but not wireless computers. The DSL light is flashing orange.

You are faced with decisions only you can make. Either pitch in and help others help you or arrange for some support to visit you and fix it.

We have a Charter Ubee U10C018.80 modem. I have a Belkin Wireless F5D8233-4 router. Like I said before, they have worked fine together for years. They are compatible.

Link please.

In reply to: Ok

And what is this "output of the router"?

Normally we use this to the WAN port, not the LAN ports. Since this model is not at you'll have to share the model and the settings.

For example in BRIDGE MODE we have to configure the Belkin router to do all the login work.

So folk forget the setup and I can't tell which mode your Belkin is in. Is it set for DSL/PPPoE or Cable?

From what I can glean, you want to use the CABLE MODEM and not any PPPoE/DSL setup.

Remember that it worked before has nothing to do with today's problem. Many folk doggedly keep pointing that out and lose time and progress to fixing it.

Still looking for details. You didn't supply a link for the dsl modem.

It appears you need to call them and have them set it up. IT WORKED BEFORE doesn't mean much here as one glitch and the settings are gone and need to be redone.

This is all volunteer. Imagine if you stopped to help change a tire and you asked for where the spare was and they wouldn't tell you? You'd have to be as polite as you can and move on.

I'm not sure if you will be upset but I'll ask. Why are the details hard to share?

Here's my bet.

The router lost it's configuration.

We have 10 posts mostly looking for make, model and details so let's work this as if all that is secret information and what to do next.

Make the assumption that this is a new setup. Press the reset and hold it on the router and then follow the setup instructions you used the first time.

I set it to factory defaults, and turned of modem and router, and it worked. Thx!
