XR500 wont let modem set IP

XR500 wont let modem set IP

When the net goes out and I have to do the typical unplug and plug back in routine this odd thing is happening...

All settings in the router are correctly set to let the ISP set the IP addresses dynamically

If I reboot the modem first, then the router, the local network goes up just fine but I get no internet.

If I reboot the router first, then the modem, I get internet but it's temporary and often flakey. My ISP tech support says that the router isn't accepting the ip changes dynamically for some reason and when the router trys to dictate the modem things don't work right.

Has anyone experiences this and if so, how did you fix it?

What is the manufacturers name and model number of the modem/optical network terminal you have in front of your XR500?

 

Are you sure it is not a combination device that includes a router?

What modem do you have?

That's not typical.

 

While many questions about routers are generic and could be answered anywhere, some things need specialist knowledge.

You might get more help, and find earlier questions and answers specific to your device, in the appropriate section for your hardware. That's probably here:

Nighthawk Pro Gaming Routers - NETGEAR Communities

Gaming routers have their own DumaOS operating system that is nothing like the one on Netgear's standard routers.

Sounds like the usual meaningless ISP tech support b*ll*cks.

 

Which ISP? Might help people to avoid it.

Re: XR500 wont let modem set IP

What is the reason you're needing to reboot so often? The best way to reboot would be to press the power button instead of pulling the power - that may have something to do with it. What is the model of the modem? It seems odd that no matter the order you boot it that the router can't pull the IP properly, usually the best boot order is modem then router so I'm surprised its not working. Its best to reboot the modem, wait 2 minutes then reboot the router and wait 2 minutes, does that work better?

Answers to the questions.

Yes my modem is just a modem and not a combo router/modem

It's a standard spectrum unit supplied for gigabit service. I don't know the manufacturer.

The reason I have to reset frequently is because I lose internet service frequently. The network stays up but I lose online service, LED indicator goes red.

As I mentioned, if I reboot the modem first (as instructed by the ISP) then the XR500, the internet LED indicator remains red and I get no online service.

If I reboot the XR500 first, then the modem I get internet.

When speaking to the tech help at spectrum, they seem to indicate that this is a problem.

I suspect the reason I'm losing service a lot is when the ISP makes a change, the XR500 isn't dynamically following suit. Why not is the mystery. All the settings are correct, as far as I can tell.

ISP tech help thought It might be a bad WAN cable. I've tried 3. No change in this behavior.

When you reboot the modem, disconnect the coax for a few minutes then reconnect before you restore the power.  This provides a reset for some of the internal circuitry.  If you have access, you may have to start looking at the signal power levels activity logs on the modem.

Do you know if your public IP is static? If so you could then put that in the Internet Setup of the XR so it always connects after a reboot
