Network problem with Fedora 7 - networking works on live cd but not after install?

This is on a laptop with realtek wired network interface and intel pro 2000 wireless interface. Networking all works fine on the live cd. After the livecd has been installed the networking won't work - can't activate the wireless card, wired interface says it is activated but won't work and the network manager icon does not show in the system tray. I'm a linux newbie, and after searching for a while I'm stumped. Any ideas?


Thanks

Fedora 7 - networking works on live cd but not after install?
COOL! A fellow Fedora user.





Ok, my friend, let us start. In Fedora 7, GNOME Network Manager is not enabled by default. I could never get it to work anyway, so it might be a good thing.





Let's see, have your root password handy first of all, and open up a terminal.





First thing you want to check is whether your network service is running or not, type as root:





/etc/init.d/network restart





just to be safe.


If your network starts properly, then we are in a good track. Make if you see something like determining IP information for ethX, then it's even better. It means that your machine is trying to resolve an IP address.





As I could never get Network Monitor to work, just disable it on the service list, it might be causing issues for you. Run as root:





system-config-services





and stop%26amp;disable NetworkManager and its companion service (should be the first two on the list).





Save your new config and run from the terminal:





system-config-network





Make sure your devices are properly configured and set to be activated when your machine boots. If your devices are deactivated at this point, activate them. Let me know if this works. If not, post details of the error logs and I'll answer accordingly.

After extra info:


Good to hear that at least your wired internet is going well. About WPA keys, once again, get your root password ready and open up a terminal.





As root, type:





system-config-network





Look for your wireless adaptor there and click the edit button in the toolbar, go into the Wireless Settings tab and use this settings:





Mode: Managed


Network Name:


(X) Specified: [the name of your network]





Key: 0x[Your WPA Key in HEX]





Remember the leading 0x (zero and lowercase x) in front of your WPA Key in HEX and to set the device to get the IP address via DHCP (provided that is what you use in your network, which most likely, it is). This option will be on the General Tab of the same window.





Optionally, on the General tab, set the device to activate at computer powerup.





Save your settings and restart your network with





/etc/init.d/network restart





If it still doesn't work, let me know.
