No wired connection after upgrade

[emrahustun]

$ sudo update-rc.d -f NetworkManager remove

Reboot

$ ifconfig eth0 10.0.0.10
$ route add default gw 10.0.0.2
$ sudo update-rc.d NetworkManager defaults

Hello.
This works for Datron laptop too.
But I need to do these after all restarts.

And second problem, it can't get DNS ip.
Any idea?

[hofa]

edit /etc/resolv.conf and put in

nameserver 10.0.0.2

make sure it is the only line in there

I am using my own laptop with 8.04 on it, thru somebody's open wi-fi around here.

On parents desktop it is no wi-fi adapter or any other possible connection except wired one. (and wired one is through dsl modem).

Well, I'm no expert, but it appears that your router doesn't use DHCP, and therefore need to set your IP address manually. If you use a router, you can probably login to your router and enable DHCP there, and then "sudo dhclient eth0" should work.

To manually set your IP address you have do something like the following:

sudo ifconfig eth0 <your IP address>
sudo route add default gw <your router's IP address>

Then you need to add "nameserver <your router's IP address>" to /etc/resolv.conf

Thank you. I put it before. Now DNS is working by coincidence.
But when i restart my machine, i have to do these things again.

My workaround for this problem is as follows:

1. Disable NetworkManager from starting up:

$ sudo update-rc.d -f NetworkManager remove

2. Reboot

3. Manually set up eth0 using ifconfig and route:

$ ifconfig eth0 10.0.0.10
$ route add default gw 10.0.0.2

4. Edit /etc/resolv.conf:

$ echo "10.0.0.2" >> /etc/resolv.conf

The exact IP addresses will be different for your individual setups, of course. You might want to try running

dhclient eth0

instead of step 3.

Works for me on Asus m3n but this is a workaround not a solution.
The Network manager is down. the IP is static.

This worked for me, though I do loose the NetworkManager. Toshiba L300D-10Q

Many thanks.

Yup. Worked for me too.

Thank you for your response. It is no router at all here. It is DSL modem.

Well I took detailed notes of all these fixes since as soon as I upgraded I had network trouble. However when I went back to Ubuntu 8.10 and on it now, the wired connection worked just fine with no fixings needed.
I assume everyone has already tried re-booting, but its working here now with no problems.

I don't know how to setup a DSL modem manually. You could wait until someone who does know posts, or you could search the web. Perhaps these links could be relevant: https://help.ubuntu.com/community/ADSLPPPoE https://help.ubuntu.com/8.04/interne...-adsl-usb.html

I found out how to get the internet to work with my router manually when installing gentoo, so perhaps there will be gentoo documentation for configuring DSL modems, if you don't have any luck elsewhere.

Good luck.

After up-grading from V8.04 to V8.10 I was getting a network connection but after a power failure and reboot I lost the network connection icon on the top bar this has came back after entering

sudo /etc/init.d/NetworkManager stop then
sudo /etc/init.d/NetworkManager start

but after entering

sudo update-rc.d NetworkManager defaults

I get

update-rc.d: warning: /etc/init.d/NetworkManager missing LSB style header
System startup links for /etc/init.d/NetworkManager already exist.

However I still can't get the network to work even after trying all the above methods posted so I still have no network connection to the internet.
