I'm hoping to find answers to a recent problem with the loss of Internet access. My cable operator says they can see my modem on their end has a good connection. They've also been out and found no problem with their equipment. Even my own computer says I have a local area networking connection yet I still have no Internet connection. I tried another ethernet cable and I've even reinstalled my windows xp operating system but with no change. Can the only conclusion be the ethernet port is bad and can only be replaced with a new motherboard since the ethernet port is directly attached to the motherboard (no separate ethernet card)?
