I just built the latest kernel from source 2.6.36 on my ubuntu 10.04 (fully updated)

The network is not working in the new kernel. Not working as in :

  1. The kernel routing is perfect

Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
9.126.134.0 * 255.255.255.0 U 1 0 0 eth0
link-local * 255.255.0.0 U 1000 0 0 eth0
default 9.126.134.1 0.0.0.0 UG 0 0 0 eth0

  1. resolv.conf is normal

  2. ifconfig output is normal

eth0 Link encap:Ethernet HWaddr 00:1c:25:b8:f9:b5

Its just that any connection attempt is not going through. I am guessing that i need to upgrade some other packages also, but not sure which ones to update (from latest source) to get network working. I really don't want to upgrade to 10.10.

System : Lenovo t61p core2duo 2GB Ram, running ubuntu 10.04 / 2.6.32, wired network with static IP.

Can you please paste the output of ifup yourDeviceHere and maybe ifconfig to your question? Also, knowing your system specs would help. –  Bobby Nov 3 '10 at 9:04

Please run

ifconfig -a

and see if there are other adapters (for example wireless), and which one is configured.

If you recall your last used IP address, or can guess a useful one, you can check and see if it is a startup configuration error versus a driver error by manually setting an IP like this:

ifconfig eth0 down
ifconfig eth0 192.168.0.100 netmask 255.255.255.0
ifconfig eth0 up

The IP address is just for example.
