Folks:

I have MOBO build with network adopter. When I tried to connect to network router most of the time I failed. few times I succeed when MAC address send to route was different. I was talking with router tech person complain about not connected, he told me same thing.

Is there any way I can rectify this problem or I should install addition NIC card and use that.

I think that you want to clarify a little more, what is the actual that you have, and how you got to the conclusion of the cause?

Currently I have one PC connected to Netgear router WGR614 V4. Everything is working. There two other PCs connect to same router wireless. They are working fine. So I know that router and internet working fine.

I just got new PC. Made same type of connection (Gateway, Submask, DNS server). It's not working. I can't even ping server (192.168.0.1). Only one time I was successful, in that case I notice device information showing on router page has different MAC address than I know. AT some point I disconnected and agin it's not working. I can not even do "ipconfig /release" or "ipconfig /renew". it's giving warning something like adopter not found (Not sure abou exact wording)

My IP 192.168.0.2
Gateway 192.168.0.1
Submask 255.255.255.0

If any specific info can help, please let me know
 
Are you using DHCP? If not, did you use the same IP twice?

In the device manager, does it notice anything wierd with your NIC?

Anything in event viewer?
 
In General you can debug the Network Setting of the computer following these steps.

Step One. Check the Network parameters in the Computer?s Device Manager. Make sure that the drivers are installed correctly; there is No IRQ conflict, and No Ghost installation. http://www.ezlan.net/faq#ghost

Step Two.Verify Basic network setting in the OS: http://www.ezlan.net/Installing#verify
If the above two Steps indicates that every thing looks good but functionally it does not work.

Step Three. Check (and repair if necessary) the Socket Layers, Winsock, and or refresh the TCP/IP Stack. http://www.ezlan.net/clean#refreshnet

I tried to use both DHCP and fix IP. I am not using same IP twice. I did not not see any problem in device manager. I can ping loopback IP 127.0.0.1 successfully. I already try step 1 and step 2 JackMDS suggested.
 
I can not even do "ipconfig /release" or "ipconfig /renew". it's giving warning something like adopter not found

It sounds like there's something wrong w/ your NIC, either hardware or software/driver.
 
You know what I mean....

My PC just connected ...and it showing completely different MAC address. Who generate MAC address? HW or SW? I have built in natword adaptor. SHould I install new NIC card?

It's generally in hardware. ipconfig /all should identify the MAC it's using.
