Why computer working as a DVR goes disconnected?

Posted on 2012-04-13
Last Modified: 2012-04-17
We have 7 IP vivotek cameras, a PoE Switch, a DSL modem from ISP and a computer that has the software ST7501 installed on it, this computer has a static IP and eventually this computer shows "null or limited connection", if I unplug and plug network cable works again without problem, I have tried putting this cable directly to ISP modem, but the problem is still present, what could be happening?

The computer has windows 7 Professional.

Thanks in advance

I would check the BIOS and OS for any sleep settings, because it sounds like the system powers down after a while.

You mean sleep settings of NIC or operating system or both?

I mean both, and check for any powering down options in the BIOS that might be active.

I will check those options and I´ll let you know.

I was wondering If the speed of the NIC (10/100) has something to do with the speed of the LAN (10/100/1000).

It sounds like the issue is almost certainly the power settings, as Callandor noted.    As for your last question, the difference in the NIC speed (10/100) vs. your router (10/100/1000) doesn't matter -- it simply means the system doesn't operate at gigabit speed since the NIC doesn't support it.

I disabled all options of energy and the NIC failed again, I have installed another NIC in a PCI-E port since a 4 days ago without failing.

I have to mention that I disabled all energy shutdown or hibernating options in this new NIC as you said before.

>I have installed another NIC in a PCI-E port since a 4 days ago without failing.

Are you saying you installed another NIC in the same machine, and it works?  That would point to the original NIC having a hardware problem, and it should be replaced.
