What can be the issue if ethernet speed seems limited to 10mbps?

[RKris23]

I have an issue were my ethernet is reduced by 90%

I've done some troubleshooting and it would apear to be either a hardware or software fault within my desktop. There is just my desktop at this connection.

I have exluded the problem being from my ISP or router/modem.(New modem, new cable, removed any interference) After I got a new modem I had all the mbps I should have, but after some hours the speed was reduced.

There had been no hardware changes, no updates, no new devices or applications between the installation of the new modem to the problem occured again.

I've tried restarting and resetting everything with no prevail. Tried messing with advanced options on the networkcard with no difference in speed.

I've asked on different forums with this issue, but no solutions to my problem.

1. It's been going on for a very long time, I really notice it when watching streams, since 1080p60 needs about 8mpbs to stream. But when downloading an update for steam or battle.net I get 12MBps
2. https://dlcdnets.asus.com/pub/ASUS/mb/04LAN/DRV_LAN_Intel_I219_UWD_SZ_TSD_W10_64_VER121897_20190801R.zip
3. Onboard
4. https://gyazo.com/c7fd14a85d225c8903d119f33f1de9ce | If you see when I got 1785mbps that was right after I changed the coaxial cable for the modem.

Hello RKris23,

Thank you for the information that you provided. You may try Intel's latest driver and check if this will fix the problem. Here is the link below:

However, since the network card is on-board. It is best that you also verify the issue with ASUS. They should be able to further help you with their own appropriate driver or further troubleshooting with the board's on-board network card.
