I had a change of motherboard of my PC yesterday. I have a UTStarcom 300R2u router configured in the bridge mode. After the change of Motherboard, I formatted and reinstalled windows XP sp2. I am trying to configure my connection and am unable to do so.I installed the LAN card alright and have the local are a connection displayed in network connections as well.The lights on the modem are working fine too. I see the bytes sent log is moving but not the bytes received.Also when I ping 192.168.1.1, I don’t get any response. However I do get a response from 192.168.1.3.I am unable to log onto the router configuration page as well. All this technical stuff is alien to me so kindly tell what and where the problem can be.The problem seems to be with my lan settings/ card only.I am able to log in using USB.Any suggestions how I can go back to Ethernet, as voltage fluctuations do cause trouble in this mode in my case.
