Network Wire Speed 1000mbps Stopped Working

Hey guys sorry if there's already a thread about this but believe me, I did search a lot and didn't find it.

So I'm here to ask some help because when I installed kali, my wire speed was working with gigabit speed. After I installed a driver for a wireless USB, for some reason the gigabit stopped working and now the maximum I can get is 100 mbps.

I already removed the wireless driver and reinstalled the ethernet. Also used the ethtool to enable the 1000 speed however when I do that my internet network just stop working, only when I re enable the 100 I have connection again.

I just can't figure out what went wrong.

It's a Realtek rtl8111h and last version of kali. I tried the driver r8168.

What can I send you guys, to help me fix this?
