Trouble connecting to internet with Fedora 14

A little background.
This past fall, I formatted my hard drive and put fedora 12 on. Worked fine until my old hard drive decided to die. During the last few days of dying Fedora stopped being able to connect to my Linksys Wireless G router(I'm hard wired), or detect any connections. I just assumed this was the hard drives fault.

Now, I have a new WD hard drive with Fedora 14 on it and still cannot connect to the internet.

I fear worst case scenario would be my ethernet port is dead but I wouldnt know how to detect that.
I thought that it might be a problem of drivers also but couldnt find anything on this subject.

Some data

Router: Linksys WRT54G-TM

Drivers usually are not an issue with a wired connection, at least not that I have encountered.

Ideally, I would try a live CD that I know can connect to the internet on a wired connection (tested on another computer) and see if it can connect. Slax or Knoppix would be good for this.

I installed Fedora 14 on my notebook and desktop as virutalbox client. For both cases, the network service did not start automatically. So, this is the steps that I took:

1) Checked the configured NIC:

Code:

# ifconfig -a

eth0  Link encap:Ethernet  HWaddr xx:xx:xx:xx:xx:xx

      BROADCAST MULTICAST  MTU:1500 Metric:1

      RX packets:0 errors:0 dropped:0 overruns:0 frame:0

      TX packets:0 errors:0 dropped:0 overruns:0 carrier:0

      collisions:0 txqueuelen:1000

      RX bytes:0 (0.0 b) TX bytes: 0 (0.0 b)



lo0    Link encap:Local Loopback

      inet addr:127.0.0.1 Mask:255.0.0.0

      inet6 addr: ::1/128 Scope:Host

      UP LOOPBACK RUNNING MTU:16436  Metric:1

      RX packets:4 errors:0 dropped:0 overruns:0 frame:0

      TX packets:4 errors:0 dropped:0 overruns:0 carrier:0

      collisions:0 txqueuelen:1000

      RX bytes:240 (240.0 b) TX bytes: 240 (240.0 b)

2) Create a configuration file for eth0 in /etc/sysconfig/network-scripts/.

Code:

#cd /etc/sysconfig/network-scripts/

#vim ifcfg-eth0

DEVICE=eth0

BOOTPROTO=dhcp

TYPE=Ethernet

ONBOOT=yes

Since I'm using DHCP, BOOTPROTO is set to dhcp.

3) Start up eth0:

Code:

# ifup eth0

4) Make sure eth0 is received IP address:

Code:

# ifconfig eth0

eth0  Link encap:Ethernet  HWaddr xx:xx:xx:xx:xx:xx

      inet addr:192.168.0.6 Bcast:192.168.0.255 Mask:255.255.255.0

      inet6 addr: fe80::a00:27ff:fe6f:542e/64 Scope:Link

      UP BROADCAST MULTICAST  MTU:1500 Metric:1

      RX packets:0 errors:0 dropped:0 overruns:0 frame:0

      TX packets:0 errors:0 dropped:0 overruns:0 carrier:0

      collisions:0 txqueuelen:1000

      RX bytes:0 (0.0 b) TX bytes: 0 (0.0 b)

5) Check start up status for network service:

Code:

# chkconfig --list network

network  0:off  1:off  2:off  3:off  4:off  5:off  6:off

6) Enable network service on startup:

Code:

# chkconfig --levels 35 network on

7) Reboot the server to check if IP address is assigned after rebooting:

Code:

# reboot

8) After the server is back up, check for IP address:

Code:

# ip addr

1: lo:...

2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000

  link/ether xx:xx:xx:xx:xx:xx brd ff:ff:ff:ff:ff:ff

  inet 192.168.0.6/24 brd 192.168.0.255 scope global eth0

  inet6 fe80::a00:27ff:fe6f:542e/64 scope link

  valid_lft forever preferred_lft forever

That's it. I hope this helped you.

PS. BTW, I turned off NetworkManager prior to these steps.

Code:

# service NetworkManager stop

# chkconfig NetworkManager off

Hey ubyt3m3, I'm having some trouble with step 2.

Also, I dont get the same output for step 1. Is having eth0 necessary?

It looks like your system doesn't recognize any network adapter. Do you know what it is? It may be a good idea to run live CD to see if that recognizes any (like frankbell suggested). If all fails, get a new NIC card. I hope a live CD sees your network adapter.

Live CD also does not work.

The Network Adapter came attached to the MSI motherboard I bought back in 2006.

Heres a couple of pics of the internals if it helps

I went ahead and ordered a new network adapter.

Will reply how it goes.

You can use any editor that you have installed on your system.

Code:

# vi ifcfg-eth0

Any text editor should work.

eth0 is the first ethernet device. You can also set it up manually instead of with a script. Fedora should have a network manager where you can go through a list of questions about your network services and it will create the scripts for you, or you can edit the files yourself if you know how to do that. You can also manually set up your ethernet. Search Linuxquestions on how to do that.

Code:

# ifup eth0

# ifconfig -a

You can try to see if eth0 comes up with the above code. You can also see if you have dhcp running.

UPDATE:

MY new NIC came in the mail yesterday. Plugged it in and NetworkManager detected it instantly. Awesome.

In case anyone is wondering it was this card. about $10 including shipping.

Thanks for all responses
