cant get to internet through cable modem


Hey, im trying to connect to the internet via a "hispeed" cable modem, running through an ethernet line to my ethernet card. YAST detected the card, but does not allow me to do online updates or connect to the internet. I also have my old laptop running windows XP connected to the same modem, only via the USB connection on the modem. Using windows CMD i ran the ipconfig /all command and got the following result:

Microsoft Windows XP [Version 5.1.2600]

C:\Dokumente und Einstellungen\Brian1>ipconfig /all

C:\Dokumente und Einstellungen\Brian1>ipconfig /all

ohh and here are the results of ifconfig run on the linux box:

Link encap:Local Loopback

inet6 addr: ::1/128 Scope:Host

any suggestions as to how I can get my linux computer to connect to the internet through the ethernet line?

any help would be absolutely great.

Thanks!

Brian

How is the linux box configured?
Have you configured the network connection to use DHCP for the network card?
Is it configured to start at bootup?

In the states, a typical basic broadband cable connection only provides one dynamic IP address based on the MAC i.e. Physikalische Adresse. The modem remembers the MAC until you remove power from the unit. I have never used a USB connection and so do not know if it is different.

Try removing power from the modem for a moment. Turn on the modem and then turn on the linux box.

(I live in Switzerland) Not sure if this is interesting...or related to the problem, but having configured the ethernet card, I look at the resolv.conf file...and it is totally blank...? I understand this is rather important for troubleshooting....?

It is related

The resolv.conf file will contain the DNS IP address information from your ISP. The information is acquired via DHCP.

If the network is not setup for DHCP and / or your network card is not configured to start at boot you will not receive an IP address nor DNS nameserver information.

Have you tried my suggestion yet?

So,

followed your advice. During linux startup i can see the network initializing, but i am still unable to either access the internet or find miror servers for system update. I am eager to get the system updates installed, as I think they will solve a lot of my other installation problems. Any other suggestions for getting ?connected properly?
Thanks!!
