Network Connection Suddenly Slowed ...

I use Robocopy to backup my video files nightly from one computer to another.

I usually see speeds of around 6000 MegaBytes/min. Recently, my speeds dropped to 1500-2000.

Both desktop PCs use Intel I218-V network cards running driver v12.19.2.45.

Does anyone have any ideas about what the problem(s) might be?

TIA

Ed

Thanks for your help. You can close this thread.

After more troubleshooting, I believe the issue is with my VPN and not the integrated NIC or driver.

Hi elprice7345,


Thank you for posting in Intel Ethernet Communities. 


For us to further check and investigate the issue, please provide the following details.

1. Please provide photos of the NIC card on both sides focusing on the markings

2. What is the brand and model of your board or system?


In case we do not hear from you, we will make a follow up after 3 workings days.

Both PCs are using the same ASUSTeK COMPUTER INC. Z97-PRO (Wi-Fi ac) motherboard with an integrated NIC.

What would cause the connection speeds to slow down that much? If the HW failed (NIC, ethernet cable, switch, etc.), I would expect it to fail hard and I would have no connection.

Hi elprice7345,


Thank you for the information. From the given information, you are using AsusZ970-Pro motherboard with integrated NIC i218-V is that correct?


Have you try updating the i218-V drivers? Since it's OEM, you might want to go with Asus drivers because Intel only provides generic driver and can be used for general purposes. To avoid any potential installation incompatibilities on OEM system, Intel recommends checking with the OEM and use the software provided via system manufacturer.


You can also try the driver below if you couldn't find one with Asus.

Please let me know if you have any further questions.
