Unhappy using the same network setting,my xp can connect to internet,bu Fedora can not.WHY?

I installed xp & fedora on my system. and both of them can connect to internect without problems.
For some reasons i re-installed my fedora, that's the very nightmare begins.
My fedora cannot go to internet from then on.

there is my network setting:

Kernel IP routing table:
Destination Gateway Genmask flags Metric Ref Use Iface U 0 0 0 eth0 U 0 0 0 eth0 202.116. 70.1 UG 0 0 0 eth0

when i tried to use Wget to connect to certain URL, i was prompted:
no route

and i did the following work:

[root@localhost setmefree]# /usr/sbin/tcpdump -iv eth0 > log &
[3] 2630
[root@localhost setmefree]# tcpdump: ioctl: No such devic

then i ping the gateway
# ping

#tac ./log
11:35:40.637225 arp who-has tell
11:35:41.637246 arp who-has tell
11:35:42.637268 arp who-has tell
11:35:44.637306 arp who-has tell

[root@localhost setmefree]# iptables --list
Chain INPUT (policy ACCEPT)
target prot opt source destination

Chain FORWARD (policy ACCEPT)
target prot opt source destination

Chain OUTPUT (policy ACCEPT)
target prot opt source destination

[root@localhost setmefree]# ifconfig
eth0 Link encap:Ethernet HWaddr 00:15:E9:42:35:F8

collisions:0 txqueuelen:0
RX bytes:8477292 (8.0 MiB) TX bytes:8477292 (8.0 MiB)

My xp system also has the same network configureation: the same IP and netmask the same network adapter, the same Gateway. it works very well.

i feel very very frustated, i don't know what is the problem.

andbody can give me a hand. tks in advance. !!!!

ok, well firstly you can see that that tcpdump command totally failed. "eth1" is an option to the -i flag, not -v, so "tcpdump -vi eth1" would have worked. but looking at the arp broadcasts, it could be that the device is failing to respond, so it's probably worth going back to that tcpdump attempt to actually see the arps and check if you're getting any replies. i'd guess that you're not. what *is* the gateway hardware? what does "arp -n" list about the known devices comapred to "arp -a" run on xp?
