Ubuntu

network manager and intel pro100+adsl router

Asked by Edson

Hello! I have a strange `behavior` with my computer. I`m using Ubuntu 7.10 livecd and when using it on that machine i can`t setup a connection through my adsl router. First of all, my eth0 card (Intel pro100) can`t get an IP address from router (SpeedTouch 510 v6) and consequently i can`t setup the ppp connection trought pppoeconf utility properly. I tried down and up the interface to see if it could get the IP but nothing happens (look in `connection information` in network manager applet, addresses are empties (all zero). The configuration of this machine is:

a7v133 motherboard
Gforce2 video card
Intel Pro100+ pci card
Athlon 1.33GHz
256 MB PC133 RAM
HD 80 GB Samsung
DVD-RW LG

Using other machine works well, the eth0 interface assigned an ip address and after configured my ppp connection everything runs well. But, i decided to test:
-in terminal, run poff dsl-provider
-right-click on networkmanager applet and click on `Enable Networking`, disabling it
-wait a while and again right-click on networkmanager applet and click on `Enable Networking`, enabling it
-and again, right-clicking NM applet and select `Configuration Information` nothing is displayed (all zero), but using ifconfig -a show my eth0 and ppp connection correctly configured and IP information displayed
This machine`s description:

AsRock K7S41G
onboard SiS900 ethernet
Semprom 2800+
752MB RAM DDR
Kingston USB pendrive (thanks to Jani Monoses script, run my Ubuntu Live`Pen` right now)

If you understood my post isn`t strange?

Thanks and best regards.

Try to stop avahi-daemon from terminal
sudo /etc/init.d/avahi-daemon stop
sudo /etc/init.d/networking-restart
try to check with
sudo ifconfig -a
your network ip.
Stop avahi-daemon to start at Ubuntu boot, using the System->Administration->Services
Reboot Ubuntu and check the network setup with:
sudo ifconfig -a

Most DSL routers can be access by using you browser ( firefox or i.e) by typing http://192.168.01 at the address bar. (This is not always the case but try it). If may ask for user and password and usually the user would be "admin" and depending on your brand of DSL the password would be given at their website. If you already installed a password then just enter it and you can browse the setings of your connections and their corresponding adrresses . If your router is configured to be automatically ip address then you should see all the machine that can connect to your router. If is manually config, you may may assigned the same number for 2 machines.

I think you make a little typo: the usual router address is http://192.168.1.1

To access to the router you must configure your network interface manually from the System->Administration->Network
IP: 192.168.1.2
netmask: 255.255.255.0

Then open Firefox browser and type the http://192.168.1.1 into the browser address bar.

"If is manually config, you may may assigned the same number for 2 machines."
changed to
"If is manually config, you may assigned different ip number for 2 machines."
