View Full Version : [ubuntu] Networking fails when fully loaded

February 3rd, 2012, 02:39 PM
I have following network config in my house:

ISP (static, public IP)
ubuntu desktop (dns, dhcp and dlna server, NAT)
wireless router used as access point (no NATing)
lan2 wireless wireless
LG TV xp desktop win7 laptop
Now, when I am watching something (1080p) on TV using DLNA, or coping big amount of data from laptop to server something fails. Even if I stop to stuffing my network by data the problem is not being fixed. After the failure is occurred I have connection between devices in my network and server but no connection outside the world. I can ping the ISP gateway but nothing more in the world even using IP (destination unreachable) and DNS name (host unreachable). When I restart the server everything is working fine again.
Do you know what can be the problem or how to find it? If you need any logs just tell me how to retrieve it and I will provide it.
Best regards, Dawid.
