Compatible eth ports for laptops are available.
Hello,
the ethernet port on your laptop is no longer working. I’m not covered under warranty, but I have strong soldering abilities and would like to replace the faulty port. Could you provide a list of compatible and size-compatible ethernet ports for your motherboard (lnvnb161216)? Also, USB external ethernet is not an option due to limited USB ports.
Welcome to the forums, newcomer!
my laptop (Lenovo IdeaPad L340-15IRH Gaming) ethernet port died.
Are you sure the port is what died and not the networking chip? A dead networking chip won't change the fact that your port is unresponsive after you've replaced the ethernet port. If the chip is what's dead, you need to source a motherboard that's listed as
for parts
and you transplant it. You sure the BIOS isn't pending an update? Uninstalling and reinstalling your LAN driver change anything?
USB external ethernet is out of question (low on USB ports).
Pick up an USB hub. What about WiFi connectivity?

I keep seeing the Realtek GbE controller in Device Manager even after uninstalling it. The LAN cable works, but Eth is not responding. Which device is pointing to the dead Ethernet port?
I'm concerned about the port's custom design—only the lead section is on the motherboard and the jack is integrated into the case. Still, you might be able to reflow each lead to resolve any cold or cracked solder joints. We don't have a specific Realtek chip model because it isn't listed in the specifications, and the driver is a generic Realtek version for Windows 10 1903 and newer. You should check the chip's markings for more details. If you don't plan to use PXE booting from it, BIOS support isn't necessary. Many PCIe Realtek LAN chips share the same 48-pin QFN package, making them compatible by pin count. This means you could potentially upgrade to a 2.5GbE chip like the RTL8125 if your original was PCIe-based, though changing the chip may disable Windows.
