Have installed several networks and finally found one the stumps me. P4 1.8GHz computer, on an Intel motherboard (D845EBT) Has on board LAN. Previously had a DLink wirelss PCI adaptor (DI-514). The customer had this computer, along with another hard wired to a Linksys WRT54G wirelss router. He needed me to set up the network and make sure that all computers were connected to the internet. I know that I uninstalled an expired Panda antivirus from his wifes computer, then an almost expired version from his. This is when I think everything went down hill. I have not been able to connect to the internet since. I have attempted to uninstall the on board LAN and reboot, to find the same issue. I tried using the wireless card, same thing. It will transmit packets, but not receive them. I can connect to the network but not access anything. I have sync'd the modem and router several times and finally decided I needed to bring it home to tear into it. Having the same router, etc, I tested it here and nothing still. I have tried direct connection to the modem and nothing. I have installed 3 different PCI NIC's and ditto. I attempted to remove and install the TCP/IP protocols and still nothing. If it is the Panda antivirus program that caused this, which I thought I saw something about a missing LSP causing some failed internet connection, and had some kind of Panda name attached to it (dummy me didn't capture it) then I will scream. I have used Panda software before with no issues. I know the routers are set up correctly, as I have 7 computers connected to mine, wired and wireless, while my customers is set up correctly, as is his neighbors, who is a customer of mine. I know I am missing one simple piece of software or something that will get this fired up again. I have been at it for oever 12 hours now and need a beer. I am hoping that some one with excellent networking knowledge can give me that one missing link that I need to get this working again. Thank you in advanced.
