maverick nVidia MCP61 Lan driver problem

**capsule** · January 6th, 2011

Hello to everyone!
I've installed ubuntu 10.10 but I can not set up the network.
Here is network configurations:

$ifconfig

Code:

I installed wicd instead of network-manager. Сan't understand what the problem is. Will be glad if you help me to solve this problem.

I can't understand the problem either. Exactly whats wrong? It seems like you are getting an IP address and you are both receiving and transmitting data.

Code:

sudo dhclient eth0
ping [the IP of your router/gateway]

$ping gw

Code:

connect: Network is unreachable

$sudo dhclient eth0

Check the cable. What is in the other end of it?

**capsule** · January 7th, 2011

I don't think that this is due to the cable as I switch the cable from one computer to another, on the other computer installed lucid and the network is operating normally. Although I found an old bug:
https://bugzilla.kernel.org/show_bug.cgi?id=8642
Maybe all because of this bug, but bug's reported date is 2007-06-16
