Wierd Problem: NIC stays on after computer is powered off

[kevman]

I have an Asus p4b266 ansd whn I power it off the NIC lights stay on and in Addition the lights on my DSL router stay as well. Anyone know why this is happening?

Most newer nics will do this. I think it has something to do with the APM and possibly WOL.

Funny thing is that it didn't do this in my old mobo (asus p3b-f) I will have to check is auto power management ot wake on lan is enable in the bIOS. Thanks

It's not anything to worry about unless you have WOL enabled. Most of the time though, WOL requires a cable connected from the NIC to the motherboard. If WOL is enabled I would disable it.

Most ATX Power supplies provide a small amount of current to the Mobo when the system is off. Nightowl is correct in saying that it's to do with WOL - The network card needs enough power to keep the link alive so it can listen for a packet telling it to wake up. You need a small 3-pin cable going from the NIC to an appropriate header on the Mobo for it to work, so dont worry about your PC suddenly turning on unless that cable is there...

Thanks, It's kind of annoying cuz it keeps my router lights on as well. But I have my WOL disabled so shouldn't it keep it off? my old mobo with the same PSU & NIC didn't do this before.
