    D5W4250 LAN died

    markolbert

      The LAN on an i5 NUC that I bought in August, 2014 suddenly died the other night. I've confirmed this is not a cabling problem -- another computer plugged into the same ethernet jack with the same cable has full network access. I can also get network access via a USB wifi dongle. So the problem seems to be in either the LAN drivers or the LAN hardware itself.

       

      I downloaded and installed the latest gigabit LAN drivers (the OS is Windows 10 64 bit, btw, with all updates installed). Unfortunately, that did not solve the problem. I've tried disabling and enabling the connection, and that didn't solve it, either. The connection just shows "cable unplugged".

       

      What are the next steps to resolve this problem? Frankly, if it's a hardware problem, I'm going to be pretty peeved -- I can't remember the last time something as basic as an ethernet "card" died on me. It's been at least 15 or more years.

          I am not from Intel, but network ports at my church are often the first thing to get "zapped" during thunderstorms (ethernet seems to be more sensitive than any other connections).  Consider looking at network port LEDs on back of the NUC and/or whatever you are plugging into (switch/router) - if the LEDs don't light then it is probably hardware rather than drivers.  My workaround when some PC's built-in port gets "zapped" is to use a USB-Ethernet dongle or Wi-Fi if appropriate (my trouble also happens just as often on the other end such as switch/router/modem, which are typically more expensive to replace).

            Appreciate the feedback, but the tests I did already confirmed it's a problem with either the NUC hardware or software, and probably the hardware.

             

            Which led me to a less than enjoyable experience with the Intel support site, which I've documented here: They Have World Class Talent and >>This Support Site?!?

                The next questions to ask is: did you try connecting with Wi-Fi on the same NUC?  Do the LEDs on the LAN port light up and flash when the cable is plugged in?  If not then it is dead.  if they do then it is software or your router maybe?. When you installed the new drivers, did you uninstall the old drivers first?
