rtl 8139 cp problems

 i have a realtek 8139 c+ onboard nic.
 When i installed kubuntu i wasnt able to set it up with dchp.
 (Other boxes here did well with the dhcp server)
 Later i set it up manually with
 ifconfig eth1 up
 and added a route with
 route add default gw dev eth1
 ifconfig show the correct output, everthing seems to be fine.
 I can ping the nic
 and it seems to work too.
 But if i want to ping the server
 it says:
 ping (.....) with .. bytes of data (this is the server)
 from icmp... destination host seems unreachable
 So i plugged another pci nic in, unfortunately again a realtek rtl 8139 c+
 and disabled the onboard nic.
 But its the same again.
 I checked all settings with somebody helpful in the kubuntu irc channel,
 and they are correct.
 Theres only one thing which seems strange.
 After booting two modules (8139too and 8139cp) are loaded.
 If i remove the 8139cp module, restart the network and try to ping it says:
 eth0 network is unreachable
 And if remove the 9139too module and load the other one it says:
 ifconfig eth0 ... up
 SIOCSIFADDR: didnt find a suitable interface (its my translation because the 
output comes in german )
 Does anybody have an idea where the problem could be.
 I dont have anymore of them 
 Thanks in Advance
