Cant connect to the internet

[spddheeraj]

hello,
I'm using HP dv6226 laptop. Installed ubuntu 10.10 inside windows 7, dual boot. My internet works perfectly in windows 7 but doesnt seem to work in ubuntu. I've been searching for a good solution and tried everything I found. These are the outputs for the commands.

$ ifconfig

only loopback shows up here.. no eth0 or anything else

Downloaded and installed e1000e manually (after installing ethtool) and then loaded module with sudo modprobe e1000e

but still there seems to be no eth0

then I uninstalled network-manager-gnome and also tried wicd... nothing seems to be working.

any help to get my internet working will be appreciated. Thank you.

Check if you have the wireless module, iwl3945, loaded, and if not, try loading it with "sudo modprobe iwl3945".

Thank you for the reply, yes it is loaded... though I'm trying to connect with wired connection. I do not have a wireless network.

edit: still waiting for some assistance...
