I bought a Dell Vostro 200 and I installed OpenSUSE11

Network Adapter: Intel 8256V-2 10/1000
Network Driver: e1000e

I applied the same network configs (ip, gatework, dhcp server .etc) But still cant reach the Network
(that config is work well on another machine which uses another brand adapter)

Is it a network adapter driver problem ?
How can I solve it ?? thank you very much
