Wired Problem

[etabeta]

Hello,
I'm a newbie with linux and use knoppix on a USB flash drive it works but I'm not able to connect to internet.

I input the same data I use with a Slax distro but Knoppix doesn't work.

Herebelow I show you what I did:
I clicked on the small terminal on the toolbar (Network Conenctions) and open it, in tag "WIRED" it show me a connection called "Auto eth0", I tried to edit this configuration but I can't the edit button is not active so I created a new connection with "ADD" and named it "Wired connection1" I input all my data (not the MAC address) in IPv4 Settings:
Method: Manual
and I input Address, Netmask, Gateway,DNS server

Then a small window appears at the bottom right corner with "Connection Established, You are now connected to WIred Connection1". Then I open the internet browser "Iceweasel" and input the Google's address but after a time I received the following error "Server not found"

Any help ?

Thanks in advance

I'm not sure what can be said - I've had similar trouble on certain connections, but with proper manual settings it worked. Perhaps there is a driver issue - why don't you post the output of

lspci -v

(that's a command in a terminal window) and the network parameters you're using.

Cheers!

I am having the exact same problem. I have tried running an Ubuntu live CD, and I am able to configure my network. I use static IP, so I need to manually configure network settings.

I prefer to use Knoppix, but I cannot edit the network settings. I open the network manager and click on Auto eth0, but the EDIT button is grayed out and is not available.

Ubuntu is using NetworkManager 0.8
Knoppix is using NetworkManager 0.7.999

I have 2 network cards. A built-in Intel adapter and a Realtek PCI card. One of them is listed as Auto eth0 and the other is Auto eth1. I cannot edit either of them.

Any ideas anyone?

Network manager is one of the most buggy thing around. Everyone has problem with it. But if you try to use 'wicd', you will notice that it has more problems compared to network manager.

Yes you are not alone having this problem with it. There are many similiar posts on the internet. I remembered having this problem too but I can't remember what I did to fix it.

Part of network manager configuration is stored in /etc/NetworkManager, since your network connections are not working, I suggest you do this :-

$ sudo /etc/init.d/network-manager stop
$ sudo rm -rf /etc/NetworkManager/system-connections/*

After that reboot and then use the GUI to re-enter your configuration again. Hopefully it will recover from the deadlock.

One possibility is to check out what the router can do for you. I need static IP, too, and I found a way to get the router to assign static addresses based on the MAC address of the network card. Assuming your router has it, then you could use it to resolve the conflict and let the Network Manager get an "auto" address that will satisfy it (even for multiple cards on one system, or ethernet vs. wireless, for instance.) It's under Lan IP Setup - Address Reservation on my Netgear router, but it could be called something different, and hidden elsewhere in the menus on another router.

I noticed that nm-applet claimed it was connected wirelessly through eth0. Curious, I stopped it and ran ifconfig. ifconfig called the lan eth0.

That is wrong. Possibly a deeper problem than network-manager?

With network-manager turned off, ifconfig said I was connected on eth0, with errors, to the lan. But I didn't test it because I am sharing service with a friend and my router has none. I sould have thought to ping it.

# ifup

returned ignoring non-existant interface eth0=eth0

# ifdown returned
interface not configured

On restarting network-manager, it took a few tries to reconnect, which is not normal. But it did connect, on a wireless interface named eth0 .

So here is 1.) turn off network-manager 2.) check wireless with iwconfig and lan with ifconfig 3.) ping my router 4.) turn on network-manager 5.) check wireless with iwconfig. Interface remains eht0 for lan or wlan. (That seems basically wrong.) No connection on lan.

Hi

I ran into this forum searching for a solution for the network problem. I did however found a solution with the help of my friend. The trick lay on finding the driver name.ko they are located on
/lib/modules/2.6.32.6/kernel/drivers/net/

mine was for broadcom 440x the driver name is "b44.ko" so I switched to root

$ su -

and then typed this command
$ modprobe b44

wala ... network initiated and started!

Best of luck for all of you folks
