Internet Lost Connection


(Edu) #1

Lose the connection from the PC with Internet continuously, however if performed from the PC Nethserver ping the server (192.168.0.200) the connection is restored.
Network Configuration:
Green Network IP: 192.168.0.200 mask: 255.255.255.0 IP gateway: null
Red Network IP: 192.168.0.201 mask: 255.255.255.0 gateway: ip router (192.168.0.241)

Why does this happen? I have reinstalled and still doing the same.
Thank you. Help me please.

Hi @edusistemas,

  • What is your (client PC) IP configuration?

  • Have you tried to ping google.com or yahoo.com from the one without internet? What’s the
    result?

Maybe you’ll need to provide proxy settings, check firewall or DNS if working properly.

Hi, thank. My Ip config:

IP: 192.168.0.100
Mask: 255.255.255.0
Gateway: 192.168.0.200

The connection works correctly per time to time I lose my internet connection.
performed a ping my gateway 192.168.0.200 (green nethserver ip) and recover the Internet connection

It seems an unusual behavior. I suspect the card may not have been performing well (driver problem perhaps). Try to continiously ping the router as well as an internet address like yahoo.com or google.com

It happens in two different servers in two different companies. The solution I’ve had to implement a scheduled Windows PCs 10 minutes ago ping task (Nethserver 192.168.0.200)

Are you using Wifi? Or maybe Windows go to Energy Saving mode?


(Edu) #7

Do not use wifi, I have disabled the energy savings in network cards for testing.
I’ll tell you how it goes. Thank you.

The problem remains the same.
When I lose the connection to the Internet if I do a ping www.google.es also becomes the connection. It is as if he lost the route where you need to go online and pinging find her again. Or that somehow the Nethserver server pinging sleep and woke up.

Just to isolate the problem, are all client PCs experiencing the same? What if you go to NethServer (while the reported computers are not able to connect to internet)…go and check if network is working (do not ping) then go back to client PCs and try again.

It is a random problem when some other PC Connection PC lose not lost.


(Edu) #11

How many PCs are supported by Nethserver?, memory is 90% Can this be the problem? the server can not process all requests Pcs

don’t get me wrong but ROTFL… :smile:

your issue has nothing to do with server’s resouces, at least if you don’t use a i486…

are you using a server class pc? or a VM?
please, give us as much details as you can about your hardware and your setup, thank you

I have the same problem in two different environments:
1 Virtual machine:
1 CPU 1 GB RAM

1 Server Xeon CPU
4 GB RAM

I have activated Nethserver:
proxy
Basic firewall
IPS
antivirus

Nethserver seems to me the best and most comprehensive Security Server Free’ve had, but this problem is driving me crazy.

Thank you.

You can’t use the same network for green and red, let’s change the green right now! :smile:
