    Default I hate DSL

    So I finished up this box I'm setting for my folks. I've worked on it at work, and here at my home. In both places, openSUSE just detected the network settings and just worked. We have multiple T1 lines at work, and I have a cable modem at home.

    I went over to hook the computer up at my parent's house, and I didn't really get an internet connection. I plugged in the DSL model via ethernet, and I could ping Google, but I got a fairly slow response. However, nothing would load in the browser. I tried Firefox and Konqueror. Both are set with no proxy. I spent over 3 hours talking to the ISP (Qwest) and they kept saying the connection was good on their end, and offered no suggestion as to how to rectify the problem.

    I went into the DSL modem's logs, and saw that it was dropping half the packets over PPP to the internet, and half the packets to my NIC. Qwest kept insisting the connection was great.

    Do I have to configure anything differently for a DSL modem? How can I fix this?

    I tried selecting the DSL option in YaST, and each time it just locked. I left it sitting for over 5 minutes, and it sat at 80% detecting NIC settings each time.

    My mother needs the computer for her at home business, and right now I'm typing on it with a great internet connection here. I have no clue why it isn't working when I plug it into the DSL modem at her house. For what it is worth, the old (ancient) Windows box when plugged into the same DSL modem is working, which leads me to believe it is some setting on this box.

    I use Qwest DSL. In the DSL config in YaST choose PPP over Ethernet, make sure your network ethernet card is recognized (if not then configure using the module provided), choose to activate the device at boot time, select the 'Modify DNS', "Auto Retrieve", and "Auto Reconnect" options. Under Network Settings > Hostname select the "Change Host" and "Write Host" options. Under Global Options choose "Traditional Method" and "AUTO" in the Hostname. Under the Address module choose "Dynamic" option and click "DHCP" in the drop down menu. Most importantly, be sure that the kernel module for the network card is being loaded during boot. Check Network Card Setup > Hardware to see if the module is listed.

    The DSL option in YaST just keeps locking up. I also tried ncurses YaST, and the same thing. It gets to 80% and hangs on "Reading Network Card configuration..."

    I'm using an Nvidia onboard NIC with the forcedeth drive. Dmesg doesn't show any oddities loading the module. And the NIC is working here, and at my work.

    Is there a config file I can maually edit somewhere to set DSL settings since I can't get into the DSL YaST module?

    Have you looked at /etc/sysconfig/network/dhcp and /etc/sysconfig/network/ifcfg-eth0?

    I am now. I'm turning on:

    DHCLIENT_SET_HOSTNAME="yes"

    Anything else I should look for?

    /etc/sysconfig/network/ifcfg-eth0

    Code:
    BOOTPROTO='dhcp'
    BROADCAST=''
    ETHTOOL_OPTIONS=''
    IPADDR=''
    MTU=''
    NAME='MCP61 Ethernet'
    NETMASK=''
    NETWORK=''
    REMOTE_IPADDR=''
    STARTMODE='auto'
    USERCONTROL='no'

    Mine were pretty identical, except I didn't have a setting for DHCLIENT_UDP_CHECKSUM.
