Default Network connection issue

Well, I recently had a power failure and when I rebooted there was a problem with the startup.* I figured FC would take care of it just like windows does and there'd be no problem.* I'm not so sure it did, a file may have gotten corrupted somewhere.

Anyway,* I am on version 6 and have been meaning to upgrade but I didn't have the time but rather than spend any more time on this I am going to do a fresh install of FC9.* I'm sure that will take care of it.

Thank all,
Jim

Default Network Connection issue

I recently installed a new D-Link DGE-530T 10/100/1000 Gigabit Desktop PCI Adapter card to connect to the internet. It was originally not recognized as there was not a driver available in debian. A new firmware-realtek update installed the driver but I had also installed another 'recognized' 3-com card, just to get the system to work. After I upgraded the driver , Debian did find the new card & set it up as eth1 while the 3-com card which worked was at eth0. As I am not well versed in this area of hardware, I just ignored the issue. I decided to try to get my system to use the new card today so I went into the box & removed the 3-com card, leaving only the D-Link card connected. Well, I was back where I started. Now my system will not connect to the network, & the router that supplies the connection will not see the card. I KNOW the card and connection are OK as the system boots into Windows7 pro and works fine. It does not work on Linux Mint Julia or Ubuntu either even though I have gone in & set the Eth0 connection to the correct intranet address & the MAC address of the card (which I got from the router interface, while Windows was booted).

Now I want to know how to get Linux to reset the network configuration. The router issues the 192.168.1.4 address via DHCP for this card. If there are files I can edit to get it working &/or test the driver to see if it works. It has been years since I had to manually configure a ethernet adapter card, & I am trying to make it as simple as possible. I have Webmin installed along with the gnome tools for network mgmt. None of these seem to get the card to be seen by the kernel.

Thanks!

Have you installed the firmware-linux-nonfree package on your
system?

Since Squeeze, a number of known working network cards are not
supported

anymore out-of-the-box and, without checking it though, it seems a
good

track for your problem.

Please send the contents of your /etc/network/interfaces file
here, as well

as the output of the following command:

*** *** lspci | grep Ethernet



Regards,

Victor

Hi John,

Support for the DGE-530T revision C1 (Realtek RTL8169 based, PCI ID
1186:4302) was added to the in-tree r8169 driver at Linux 3.0.2. This was
incorporated in Debian's linux-2.6 as of version 2.6.32-36 (part of the
6.0.3 point release).

Firmware from userspace is not required for use of this device.

Your network configuration likely requires adjustment. Through udev, Debian
systems use persistent names for network interfaces; your DGE-530T device
will still be assigned eth1 even when the 3Com card is physically removed.

The output of "ifconfig -a" (as requested by Victor Nitu) would have been
useful to confirm the current interface assignment.

You can either:

* Modify /etc/udev/rules.d/70-persistent-net.rules to assign eth0 to your
DGE-530T device (e.g. NAME="eth0"). The relevant line to adjust should
be present under a comment such as '# PCI device 0x1186:0x4302 (r8169)'.

After modification, save the file and reload the r8169 module using the
command "modprobe -r r8169 ; modprobe r8169" (alternatively, execute
"udevadm trigger"). Run "ifconfig -a" to confirm interface assignment.

* Amend your system's network configuration (/etc/network/interfaces) to
use eth1 instead of eth0, then bring the interface up using "ifup eth1".

The interfaces(5) manual page describes this file's format (execute "man
interfaces" to view this), see also other information available at [1].

Note that other application configuration files (e.g. iptables based
firewall) may require to be similarly updated.

This is incorrect, as two iface stanzas are stated for loopback. It should
contain a line for the eth* network interface (e.g. "iface eth0 inet dhcp").

-----------------------------------------Ha!!*Thanks Geoff. You really hit this out of the park. I,m now up & running with a new learning experience under my belt & a MUCH faster network.
Again Thanks & thanks to all of you who assisted especially Victor.frosty
