Ethernet slower than WIFI (I'm desperate)

I have contracted a plan of 50 megabytes and it was always wonderful until a few days that out of nowhere I started receiving only 6 megabytes, by cable. With the other devices over WIFI I am doing excellent and I enjoy the adequate speed. I clarify that I did not touch any configuration and the network card is gigabit and is well configured.



I tried different applications like NetAdapterRepair.
I updated the drivers.
I booted into safe mode with network functions and performed a clean boot.
I tried another modem port and tried another ethernet cable.
I performed the test on another computer connected to the modem and if it receives the entire connection.
I also activated the Windows Auto Tuning application (as another post said).

Nothing worked.

Welcome to the forum. Does the network card show its çonnected at a gig or 10 met have you tried another cable and port.. have you tested the speed with nothing else using the net is the card set to full duplex

Yeah, I tried another cable and another port. My network card works at gigabit speed and is in full duplex

I use Windows 10 and my network card is Realtek PCIe GBE Family Controller #10

When I look at the configuration of the adapter it says that the speed is 10.0mbs (although I configured it to be 1.0 gigabits) can this be an error?

If its set to 10 met that's your problem often set to full duplex will cause it as that sends and receives at the same time most home routers can't handle it and it keeps having to resend data so it drops the speed to stop the problem

Why does this happen now and not before?
What should I do to fix it?

How should I set it up? I've already tried several cables.

I FINALLY SOLVED IT!
All I had to do was disconnect the computer power supply for a few minutes. I honestly didn't think it would work, but now my computer works at 1.0 gb again.

Thank you, everyone
