Hi, I am using FC5 with dual-booting.

On Windows, there is no problme with internet conneciton.

But in FC5, I always lost my connection within 5 or 10 mins after booting.

I checked the connection with ping.. At first, ping to my default gateway is working well but when I tried to connect to some webpage(not specific webpage) ping does not work anymore and lost connection (unreachable).

I think you guys need information about my network setting and other things. Please tell me what information is needed then I will add it.

Post the output of
1. ifconfig
2. cat /etc/sysconfig/network-scripts/ifcfg-eth0
3. route -n
4. cat /etc/resolv.conf
5.ping <o/p of 3rd command>
