Replacing a built-in Ethernet jack with a NIC

Hi, Make sure you also do a power discharge by disconnecting the power cord and pressing the power button 2 or 3 times to drain all the energy then reconnect the power cord. I have seen s... Go to the full post »

I use a wired Ethernet connection on my HP desktop (5 years old), but also has wireless connection capabilities.  I use Google Fiber as my internet provider (1000 mbps), which is what I get using wired Ethernet connection.  My Ethernet connection stopped working, this was determined by plugging the Ethernet cable that was plugged in to my desktop in to my laptop and the laptop had the 1000 mbps.


I have switched my desktop to Wi-Fi and now I have internet, but at only 200 mbps. 


When I checked for the network card in my computer to see about replacing it, I discovered the Ethernet jack is solder directly to the motherboard.   I really do not want to have the jack replaced on the motherboard.


My question, can I install a network card in to one of my open PCI slots without any conflicts with the current Ethernet adapter that is part of the mother board?  See attached photo showing Ethernet port (Silver box circled in Blue) attached to motherboard.


If I can install a new card, any recommendations on a decent NIC that will work in the following PCI slot, would be appreciated.  Especially something that can handle the 1000 mbps speed.

                Slot Usage           Available

                Slot Designation               PCI Express x1 Slot 1

Should be no problem to install a new NIC.  You can get a decent one for $9.99 on Amazon: EDUP Gigabit Ethernet PCI Express PCI-E Network Card 10/100/1000Mbps RJ45 LAN Adapter Converter for Desktop PC


Before you order it go into Device Manager (search for device manager and hit Enter) then click on the arrow in front of Network Adapter.  Locate your current non working Network Adapter, right click and Uninstall device (do not let it remove drivers if it asks) then Reboot.  Sometimes that is all you need to do to fix it.  If that doesn't help you can try Update Device.  If it's still dead then Disable Device and order your new one.


It's Amazon so you can send it back if it doesn't work.

I have seen several cases where this brings the network card back to life.

Thanks for the help!!


As an update, I uninstalled the network adapter as instructed and did the power discharge.  Seem to help and I can get internet through my Ethernet cable again.  Although my speed is only half of what it has been, so I ended up getting a new NIC and installed it just to see if my speed would change, but it is still the same as with the original network adapter.  I will need to take this up with Google Fiber.


I consider this issue resolved.
