lose the net in fedora

[kantor_98]

I am in the UPC cable network, in Romania. I have a AMD 64 Athlon computer and have installed on it win XP and fedora 7. When I installed Fedora, everything was OK with my network, I was able to use it for yum (I installed adobe reader, xnview, vlc, etc, valknut, etc). In the last week I have not open fedora, only win. Now I entered in fedora and I see that the net is not working anymore ! I have 2 broswer (one is firefox) but they are not working anymore ! In win everything is ok !
Do anybody have an ideea of what could happen ?
In win I use also an DC++ client - could it affected fedora ? I can't imagine that, but...
Thank you all !

to keep it as simple as possible, the first thing i would do is run system-config-network (as root) and make sure they interface is setup correctly (static or dhcp, gateways, nameservers, etc)

The problem is that when I install the first time fedora, the internet JUST START without any other configuration from my part ! I really do nothing !

Well it's because you have setted all the tasks at the beginning (during the installation process, i guess).

I believe also that you are running a dhcp somewhere.

Please drop the output of:

code:
ifconfig -a

well.. at least that tells us your appear to be getting a valid ip. what are the results of the following commands:

1) route
2) cat /etc/resolv.conf
3) ping 72.14.253.103
4) ping www.google.com

Sorry for may delay - there are sometime more important things than computers !
When I enter again in fedora to try what you indicate me, I had a surprise: the ne now was working ! I did nothing, really ! So... I am a little confused, because I don't know what was it !
Thank you, anyway ! If the problem reappears, then I will give the commands that you tell me and see what happens !
All the best !
