My Intel 218-v adapter has not been able to reach an internet speed higher than 100mbp/s.
My ISP provides a speed of 500 mbp/s.
When I put the 'Speed and Duplex' setting on 1GB it disconnects completely and with 'Auto Negotiation' it just gives a mere 100mbp/s and sometimes even switches to 10mbp/s.
I've tried different cables, but that did not turn out to be the problem.
Installing the latest drivers didn't seem to help either.
Perhaps someone here knows a solution?
Thank you for posting at Wired community. With regards to the issue encountered, can you check the corresponding setting on the router/switch that connects to the ISP. Please ensure the same speed and duplex setting on both the router/switch and I218 . e.g. If you configured as Auto negotiation on I218, the same should be applied to the router/switch.
As I218-V is an onboard NIC, what is the brand and model of your system? Is the driver you downloaded from the board vendor? We have Intel driver available for download but this is generic version we do not guarantee 100% compatibility.
Have you contacted the board vendor to isolate the issue since this is an onboard NIC, it is recommended you contact the board vendor for further assistance.
