I have called Verizon twice on this and they told me that my Network card is bad but I took my computer in and it is not my computer. Our house is all Cat5 wired with the modem located in the Cat 5 box in the closet. In one of our kids bedrooms, we are trying to connect a computer operating on XP and it will not connect to the Internet. It is not the cable or jack because there is already another older computer hooked up in this room to same jack and it works fine whenever I switch it back over. I have taken the XP computer and sucessfully hooked it up in another room and it connects just fine to the Internet. I have spent hours on the phone with Verizon going through all the set up stuff, local area connection, Obtain IP address and DNS server automatically are both checked, we have reset the IPCONFIG, tried to ping with no success. This is driving me crazy because the computer does work fine in another room. Any help as to what could be causing the computer to not work in this room would be greatly appreciated.
