Why dose my internet work in windows but not in opensuse 10.2 on a dual boot computer?
in linus i can ping 127.0.0.1 and 127.0.0.2 but not anything else.I have set up a nework.

The intermet works fine for windows.

Probably because you have drivers for the internet connection hardware installed on Windows, but not on Linux.

Could you provide more information. Which network device does your computer use? (Use "sudo /sbin/lspci")
Does "lsmod" show that there is a kernel module loaded for the device. Also, look in the HCL on this site to see if information is available. Does your network have a DHCP server, such as a NAT router? If so, did you configure the device to automatically get an IP address. If that is the case, then the device's IP address, the nameserver addresses and the gateway address will be supplied. If not, you need to manually configure these values.

You can configure the network in YaST2. Select "Network Devices" -> "Network Card" to get started.
Also read the documentation on the installation disk in the docu/en/ directory. There is a chapter on networking.

I have a dsl connection with frountier. My network manger seems to be up and working. I did go to yast and network and set up both a network card and dsl. the computer wanted two ip addresses but what is the second ip. still no internet connection.

Is your DSL device a modem or is it also a NAT router? If it is also a NAT router, you may configure the ISP information in the router through a web interface and configure your device for DHCP.

I don't have a DSL modem, so I can't walk you through yast. There are different types of devices and different point to point protocols that might be used. There are also differences in the way different providers in different Countries tend to use DSL. Chapter 4 in the OpenSuSE-startup manual covers DSL network installation. It's in the /docu/en directory of the installation disk.

I am having a similar problem. I am using a Linksys WMP54GS with a
2WIRE wireless modem. I have installed ndiswrapper and sucessfully installed the driver from the disk that came with the wireless card.
When I try to update the ESSID, either by GUI or CLI using the command <iwconfig wlan0 essid "myessid" > the essid option remains
at the "off/any" rather than updating. Has anyone found a solution? Is there a patch for the kernel that corrects a bug?

Actually, It looks like your problem is very different. The OP has a DSL modem. You are using a wireless device to a AP router.
I'm not certain from your message if setting your ESSID identifier is the only problem you have.

Does Mephis have a ifcfg-<device> file to configure network devices? Does "iwlist scan" show results? Does your wireless device have an IP address? Are you using wpa encryption?
