have to keep restarting network

I installed Fedora 13 in my machine. Was installed properly. I had internet and everything initially. I have a router directly connected with a cable to my lan. After installed everything I "added" my machine to an already existing network with only windows machines. I added my machine to the network with a cable. My problem now is that I can't access internet. However, I can see all other computers in the network, ping, browse in the network, everything. can't ping anything outside the lan, access the Windows mail server or access any internet site. However if I restart the network with "service network restart" I can browse for a few seconds then it goes down and I have to restart again to continue browsing.
These are the configs;
ifconfig:
eth0 Link encap:Ethernet HWaddr 90:E6:BA:51:50:7D
inet addr:192.168.1.128 Bcast:192.168.7.255 Mask:255.255.248.0

cat /etc/resolv.conf

nslookup www.yahoo.com

sudo iptables -nL
Chain INPUT (policy ACCEPT)
target prot opt source destination

Chain FORWARD (policy ACCEPT)
target prot opt source destination

Chain OUTPUT (policy ACCEPT)

Does anybody know any kind on configuration I have to do in my linux box or in my cisco router to make this work?
