Ethernet Is not working, Need Configuration

I am using Sony vaio E series laptop. Previously, I was using my E63 nokia phone as modem for internet connection and i have installed K-internet in my Opensuse OS, and configured wvdial.conf as follows:
[Dialer Defaults]
Init1=ATZ
Init2=ATQ V1 E1 S0=0 &C1 &D2 + FCLASS=0
Init3=AT + CGDCONT=1, “IP”,“bsnlnet”,"",0,0
Baud=4608000
Modem Type= Analog Modem
ISDN = 0
Pjone = *99#
Username = user
Password = passwd
New PPPD = yes
[Dialer BT]
modem= /dev/rfcomm0
[Dialer USB]
modem = /dev/ttyACM0

But now, I have Reliance Brodband Connection through LAN. when I am Pluggin in my LAN cable in my laptop YAST Network Configuration Showing Marvell Ethrtnrt is not Configured, When i am going to configured that part it’s showning me no Enther net present or Configured By ny Hardware Is detecting ethernet. So, I have concluded that it might be the problem with my wvdial.conf. Also, additional information are as follows:-
OS- Open suse 64bit, Version- 11.2

So please anyone can solve this matter, cause I cannot Connect to my Internet now? What should I do to have this Problem Fixed? Please revert back.

Please do not duplicate ANY MORE posts of this question, I deleted 2 others.

If you no longer plan to use the old wvdial connection, you could back up your settings and remove it.
If you plan to use the LAN connection, then you should be using traditional ifup setting in the Yast - Network settings.
Normally when you connect a LAN ethernet it just works.

I got that, soory for posting same post. I have also gone for that part what oyu have said, but I think ifup seetind deals with static IP address but i have dynamic type of address. Please revrt back. I want help.

No ifup will deal with either, just select DHCP
