couldnt connect to internet

Hi guys,

I’m very new linux user. I have installed openSUSE KDE 11.3 on my notebook.
Everything looks great, but I can’t connect on internet. It looks like dhcp don’t work. Wireless works fine, only auto eth0 don’t work!

Please help!

I would ask you to go into YaST / Network Devices / Network Settings / Global Options Tab and set the bullet for “User Controlled With NetworkManager” if not selected as this is the normal way to use NetworkManager. Once set, you may have to run NetworkManager manually as a normal user the first time to see it in the icon tray, but after that it should load automatically. For wireless connections in KDE, it is said you need to run Kwallet to keep track of the system passwords. So look at this options as well.

Thank You,

OK it was like that, but problem is when I connect cable to notepad auto eth0 was recognized and problem is when it tray to obtain IP address. So i guess DHCP server doesn’t work! It’s set that IP automatic, and DNS automatic

So, you have a laptop with Wireless, but your want to use a hard wired connection, Is that correct? What is your hard wired connection going to at your home (or office)? For instance, I use a D-Link Hard wired Router, connected to Time Warner Cable. The Router provides the DHCP function and assigns the IP address. How does your hard wired connection work? Be as specific as you can, even giving model numbers can be helpful.

Thank You,

Scientific Atlanta EPC2100R2 cable modem. Now I’m using that connection on windows (on my desktop computer) its local area connection (VIA Rhine II Fast Ethernet Adapter) if it helps.

So if Wireless works, one would wonder why you just don’t use wireless? However, the issue may be solved by going back into your YaST / network devices menu and Unselected Network Manager and switching back to ifup mode. Consider than using ifup as root, you can disable the wlan0 and force eth0 to be used. However, switching back to wireless mode might be a problem in that you must undo this setup. When wireless is working and see networks (even if you can’t connect to them) will most likely prevent the wired connection from working. So, disable the network manager and then try these terminal commands:

su -
password:
ifdown wlan0
ifup eth0

I assume that the wlan is set to 0 and eth is set to 0, but they can also be 1 or 2 and so on. If you do not disable the Network Manage, the ifup/down commands will not work.

Thank You,

But I don’t have wireless at my home, so thats the reason why I want to fix this problem. This is what I get after commands

linux-qyhg:~ # ifdown wlan0
wlan0 device: RaLink RT2561/RT61 rev B 802.11g
linux-qyhg:~ # ifup eth0
eth0 device: nVidia Corporation MCP51 Ethernet Controller (rev a3)
DHCP4 client is already running on eth0
DHCP6 client is already running on eth0

So, did this help? You can issue an ifstatus command to see what is going on.

su -
password:
ifstatus eth0

Thank You,

Still no connection

linux-qyhg:~ # ifstatus eth0
    eth0      device: nVidia Corporation MCP51 Ethernet Controller (rev a3)
DHCP4 client (dhcpcd) is running
. . . but is still waiting for data
DHCP6 client (dhclient6) is running
. . . but is still waiting for data
eth0 is up
3: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN qlen 1000

    inet6 fe80::219:dbff:fe39:ea70/64 scope link 
       valid_lft forever preferred_lft forever

With openSUSE running, cycle power on the Scientific Atlanta EPC2100R2 cable modem, wait a few minutes and try the “ifup eth0 & ifstatus eth0” one more time. This is a setup issue with your cable modem I think. I would try this sequence of events:

Cycle Cable Modem Power - wait a minute or so - Open Up a terminal session:

su -
password:
ifup eth0
ifstatus

Try this and report back.

Thank You,

Now is workinglol!lol!lol!

Thank you!
