View Full Version : F16 no wired network connection

6th December 2011, 02:52 PM
I have Fedora 16 running from a thumbdrive (created using the tools provided on Fedora's website). I'm having trouble getting the wired connection working on the computer I intend to use the LiveUSB to boot from. I have tried setting up a wired connection manually, but haven't had any luck. A previous installation to hard disk of Fedora 14 on the compute had no trouble with the wired connection. Windows also runs on the computer and has no problem with the wired connection. I'm unsure what the problem is, and would appreciate any help.

edit: The problem must relate to running Fedora 16 from a USB drive, and not be related to hardware issues. I think this is the case because the wired network runs fine on the target computer when installed to a local disk "out of the box." Second, both the wireless and wired connection don't work when a computer with an installation of Fedora 16 with working wired and wireless network connections are booted from the USB drive.

ifconfig -a

Try running:
ip addr
Unlike ifconfig, this lists wlan (for me at least)
Ifconfig lists only already set up connections, afaik.

Afterwards, you could enter:
# ifconfig WLAN0 up
# dhclient WLAN0
Where as WLAN0 is the label of your wlan connection.

Eerg.. wrong read.. no wireless, but wired...

Well em1 is your wired connection, try:
# ifconfig em1 up
# dhclient em1
# indicates that it should be ran as root.

Hope this helps.

It looks like em1 is up. What is in your /etc/resolv.conf file?
