Ethernet dropping out and laptop loses connection


I have Vortexbox (fedora distro) installed on a laptop which I am using as a media server. I would have issues where I thought the laptop would go to sleep and disconnect itself from the internet. The computer boots in command line mode and what I would notice is that the screen would go blank and then I would have to go to the computer and jiggle the trackpad and it would wake up.

I posted about it and got responses related to the gnome desktop which I could not find the files referred to in the answer. I tried using setterm to keep the computer awake setting blank to 0 and powersave off. The same thing happens even with the monitor on and the screen display on. A gesture on the trackpad seems to wake the ethernet back up.

Here's my old post: http://www.linuxquestions.org/questi...-awake-839150/

Any suggestions. Everything else about this situation is perfect. Vortexbox is easy to set up and it does everything I want, DLNA, streams to my squeezeboxes, etc, but this ethernet cutting out is exasperating.

I looked in the BIOS when I first had the issue and there are options for powersavings.

go into bios set to none plug n play O/S that what linux likes. If you are using a broadcom wireless let us know that.

The bios has no options for PnP. Only options are for passwords and for boot order.

My system (focusing on what attaches to the linux server).

The laptop is wired into the router.

My iMac which is wired into the router accesses the vortexbox. My 3 squeezeboxes are all wirelessly accessing the vortexbox.

go into your router and see what the settings are on that lease. I had to set my lease time from default 48 hours to more for my wifi connection then I stopped having the problem. If you are using the broadcom card with the sta driver then this is a none bug.

I tried setting the lease time to 60 hours and still have the issue (it happens even after 12 hours). I have integrated Ethernet in my laptop, i'm not sure if it is Broadcom. Would getting an external PCMCIA ethernet card potentially fix the problem?

I was looking again and I noted the following. Both the yellow and green ethernet lights were on. However, pinging the laptop resulted in no response.
I ran acpitool and got the results below. It looks like the computer is in c1 state for a long period of time. Perhaps it is going into C1 and just getting stuck? Is there a way to prevent this? I'm at my wits end. I increased the lease time last night and it conked out this AM. I use the laptop for Subsonic so at times I will try and connect from my phone and it will not connect when this is happening
