means the Ubuntu are still recognize my driver and hardware right?

[pokipoki08]

gksudo gedit /etc/network/interfaces

Add & save text in blue below into file /etc/network/interfaces


auto eth0
iface eth0 inet dhcp

Run these commands at the terminal


sudo /etc/init.d/networking restart
ifconfig

If all is well, you should see an IP address in eth0.

Note : You can only have 1 active network connection at any time. So, it's either the wired (eth0) or the wireless (wlan0).

When you want to try connecting to wireless, disable or comment out those text in blue in /etc/network/interfaces

[chili555]

Please do, in a terminal:
sudo modprobe forcedeth
sudo lshw -C networkIs your card still unclaimed? Now do:
ifconfigDoes your interface eth0 reappear?

If this fixes it, we will have to take some steps to make this, hopefully, permanent.

[kienseng]

i type already, but it show me this....

sudo: unable to resolve host Ubuntu

why the Ubuntu failed to bring up eth0?

even in the ifconfig there the eth0 still not appear

[kienseng]

Please do, in a terminal:
sudo modprobe forcedeth
sudo lshw -C networkIs your card still unclaimed? Now do:
ifconfigDoes your interface eth0 reappear?

If this fixes it, we will have to take some steps to make this, hopefully, permanent.

yes, it works, you sure this can work permanently?

[kienseng]

it works now, but everytime i restart it not working again and i need to type the command over again.

it show this error after i typed sudo modeprobe forcedeth

WARNING: /etc/modprobe.d/blacklist line 42: ignoring bad line starting with 'sudo'
WARNING: /etc/modprobe.d/blacklist line 44: ignoring bad line starting with 'mkdir'

[chili555]

Let's see:
cat /etc/modprobe.d/blacklistI wonder if the failure of forcedeth to load is related. Let's fix problem #1 before we move forward. This:
sudo: unable to resolve host Ubuntubothers me, too. May I please see:
cat /etc/hosts
you sure this can work permanently?Yes, indeed. Thanks.

[kienseng]

this is what it appear after i typed the cat /etc/modprobe.d/blacklist

[chili555]

sudo gedit /etc/hosts to make it look like this (a bit of guesswork here):

sudo modprobe forcedeth
sudo /etc/init.d/networking restartNote any errors and tell us if your wired connection comes up.

[kienseng]

i'm sorry, but it doesn't work, the eth0 wired connection do come up, but after i restart then it not working again, i need the command all over again to get it working, is there a solution that i can get it automatically working when the cable is pluggled in?

[chili555]

Please sudo gedit /etc/modules and add a single word on its own line:
forcedethProofread, save and close. Use any other text editor if you don't have gedit; kwrite, kate, nano or vim will work as well.

Reboot. If your /etc/network/interfaces file contains this:
auto eth0
iface eth0 inet dhcpthen you should be connected at boot.

[kienseng]

k thx.... problem solved...

[altonbr]

Why was this so hard to fix? And the use of the command line? Ugh.
