I just assembled a Pentium 4 rig with ASUS mobo P4S800D-X and apparently I am having internet connection issue with wired connection. I am connecting through a router and all internet connection are test to work fine with my other computer. I was able to connect wirelessly using a USB internet adapter. It is just the wired connection that is not functioning. I have consulted with ASUS tech support and at first they told me to uninstall the network adapter and reinstall and still problem not solved. Then they said could be a TCP/IP stack issue so they told me to download the SP3 and still issue not resolved. Does anyone have any issue similar to this that can help me figure out this weird problem?? Thanks.
