Ethernet cable connection with lower speed than wifi

[MadScalp12]

Dear, good afternoon.

I would like to ask for help with a problem I've been having for a few months.

I've been noticing for some time that my internet connection is slower just with the ethernet cable. Today I have a CAT7 type ethernet cable, a contracted speed of 500mbps and my network card is Realtek Gaming GbE Family Controller. For some time this connection was limited to 100 mbps. Since I've been observing this problem (limit of 100mbps) I've been looking for solutions to adapt the ethernet speed to my contracted plan. This week, after a Windows update (KB4023057) my cable internet stopped working.

I fixed the ethernet cable problem by changing the "Auto disable gigabit" setting from "disabled" to "re-connect battery or AC"

However after the update, the ethernet cable is now limited to 10mbps

I've really tried everything. I changed the "Speed & Duplex" setting to 1.0 Gbps. I changed the "WOL and Link Speed" setting to Do not slow down. I updated the driver using the manufacturer's website (REALTEK). Reverted update. I uninstalled and reinstalled the driver. I formatted the notebook to a clean version of Windows. Test with two other Ethernet cables (one Cat5E and one CAT6). I configured gpedit to not throttle the connection. I'm really upset about this problem and afraid it's a realtek chip problem (soldered to board)

On the internet we find many cases similar to mine. All the proposed solutions that I found had no effect.

Could someone on this forum help me solve this problem?
