Rtl8168/8111 pci-e lan failing

Try different cable, modem, router, but seriously if its the actual lan connector on the motherboard that is bad, buy a new motherboard.

Check the warranty on the PC.

You can always but a lan card, see what you have for PCI slots on your motherboard and buy a card from Newegg.

It is not worth fixing an onboard lan.(ethernet) one that's built onto the board.


Look at these.

1) How do you know that PCI slot is not working? Tried another PCI expansion card in it? Perhaps another LAN adapter card?
(Ethernet Card)

A LAN adapter card will go bad before a PCI slot will.

2) PCI expansion slot is bad? No other PCI slot to use?
Then here is a suggestion,

Plug it into any available USB port on the computer.
It is a GigaByte Ethernet solution, also. (10/100/1000)

If it is onboard lan you would need to send the entire motherboard for LAN repair which is an expensive process.however if it is a LAN card that you have connected seperately in PCI slot, then replacing the same is a much cheaper, easier and better option.

hi! I think u need to install drivers in your PCI internet/LAN Card or built-in LAN
Please check the brand of Motherboard if it is built-in or the PCI Card Brand. and browse it in the net with another PC with the NET connection, to the manufacturer websites. and search it with corresponding model of the motherboard or the PCI Card. and download the Driver's and save to USB and paste it to ur PC and install it.
if this tips is helpful. please rate it. thank you.

Run a detection program. PC Wizard is in my opinion the best and it will provide you with a lot of extra data.

Any brand that is made to fit in in a PCI slot. Try Best buy or Tigerdirect.com. Also, go into your bios settings when computer 1st starts and shut off the built in lan on your motherboard (see computer manual or online support for your brand)

you will need to know the mother board manufacturer and model mumber to get that. if you cant get that info just get a pci nic card. and dont worry about the on board LAN. they are 10 to 30 dollars

change your media type auto to 10 mb full duplex

you found it in your lan card properties

do you have a pci network adapter intalled with the proper drivers ? did you plug in ethernet cable directly into current pci lan card it will be located on lower part of back of computer? this will eliminate the problems with the router just to see if pci lancard is working or not . if the lan card is working unplug cable and plug in router and then try with router plugged in u might need to reset the router in order for it to work with lan card . if ur using and onboard lan eg attached to the motherboard then you must go into computer bios and enable onboard lan and then the ethernet cable should work with no problem good luck i hope this helps you get up and going getback to me if there are future problems.

It could be one of two issues. The cable has gone bad. Replace the cable. Or, the LAN port on the computer has gone bad. Replace the LAN port. If it's a built in LAN port, just add a PCI one; they can be purchased for under $10.
