Continuous cable/dsl router lights

By fesmith49 ·
I have a three node peer to peer network sharing a cable connection. The network itself operates great. Connections to the web are fast and clean. The nagging issue for me is the port lights stay on all of the time even if the pc is powered off.I have placed the card into different slots. Move the patch cable to different ports on the router and tried a different NIC. All of the NIC's connected to the router are 10/100. The only way to get rid of the lights is to disconnect power to the router or the pc. What could be happening here? The router is a Linksys BEFSR41.

Hi,

Modern nics have permanent power applied to them. Its how the "Wake on LAN" option functions. You can have your PC go into sleep mode but if any network activity comes along, it'll wake up automatically.

Its possible there will be a setting in your BIOS to disable this if its a serious problem to you. Look under the power options in there.

Cheers,
Tim.

Answer 1 is correct. Most modern NIC's are designed to have power on all the time, for wake on LAN as thechas said, and also to enable remote logins. That may be what's concerning you, that someone may have the ability to attach to your PC while youare out. I wouldn't worry. If you have a router, there should be some basic protection like NAT on the router.
It sounds like it's performing as designed.

You may not have tried this, and I want to be sure that you and I and everyone reading this knows what's happening. Turn your PC off. Look at the back of the PC. You should still see lights on the NIC lit up. If this is a very old PC you may not, but any PC made in the last couple of years should still have the NIC lights on. When you see that, you'll know that the NIC is still active. That is what is making the lights on the hub flicker. It's supposed to work that way.
Let us know what you find.

Are you with AT&T or any other highspeed service. I work for them as troubleshooting and I will inform you that most Dynamic Networks are broadcast which means also along with the nic that anytime anything outside your modem on the network request info from the network everything is hit with the request. Which is why you may notice that sometimes you are getting hit multiple times with packetts from other users on the network. This is not necessarily someone wanting to break the network you are on but just requesting an IP.

I am with Time-Warner. If I'm understanding your comment; the other nodes on the network are requesting an IP. I don't think that is the case because the other nodes are not powered up all the time. I don't think it outside either because of the firewall with the ISP and also because of the NAT within the router.
