Will internet cut off if I do not have a PC connected to cable modem?

Question

My cable internet provider is Cox.
I am getting internet service interruptions, and I am wondering if it might be because I don't have a PC directly connected to the modem or the router.
I have my Motorola cable modem in the garage connected to Linksys router. My PC and notebooks are all on wireless network sharing internet connection, printing and so on.

Everything worked fine until two days ago where I started getting a lot of service interruptions. Local network is fine. It's just Cox internet that cuts off.

- My question is do I need to have a PC directly connected to the modem or the router for Cox Internet to work?
- Do I need to change any settings on the router?

TV signals are fine and when I called Cox they did not see any problems with the modem or signal.

Thanks

Answer 1

No, your router is all that the Cox network sees. You router hides the home network, in that all communications on the Cox network appear to originate from the router.

It sounds like your problems are with the Cox network, could be an installer working between your home and the Cox head-end, the Cox support people probably wouldn't be aware of that type of activity.

The only thing you might try is to restart (power off for 1 minute) the cable modem and the router. Turn the cable modem back on first, then turn on the router. If you do that, reboot your PCs too, just to make sure all the addresses are reassigned correctly.

Answer 2

You do not..either the issue is with COX or your router. Some of the older Linksys models do not have a built in router, just a switch & plugs. If you do not have a true built in router and are operating more than one PC, you will have conflicts. You might want to test the cox service by connecting directly to the fax modem.

Your router should be occupying the connection. It directs packets sent from the DNS Server and the DHCP Server. A PC should not be necessary.
