My Netgear modem CM500 worked two days ago. When I tried to use it in an apartment yesterday, it did not work.The ethernet light was orange with no internet service when the modem is connected to a wireless router or to a laptop.

Can you connect the laptop to the modem without using the router?

This would check that the modem is working properly. Then you can start working out why the (unknown) router does not connect to the Internet through the modem.

Remember, when connecting to the Internet you have to do things in the right order:

Be sure to restart your network in this sequence:

• Turn off and unplug modem.
• Turn off router and computers.
• Plug in and turn on modem. Wait 2 minutes for it to connect.
• Turn on the router and wait 2 minutes for it to connect.
• Turn on computers and rest of network.

While many questions about routers are generic and could be answered anywhere, some things need specialist knowledge. Your question is about a cable modem.

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:

Cable Modems & Routers

I will ask the Netgear moderator to move your message.

In the meantime you could visit the support pages:

Support | NETGEAR

Feed in your model number and check the documentation for your hardware. Look at the label on the device for the model number.

You may have done this already. I can't tell from your message.

I mention it because Netgear stopped supplying printed manuals and CD versions some years ago and people sometimes miss the downloads.
