Ethernet issues

Question

I can't get my RTL8111F Realtek ethernet embed chip to work like it should.I sincerely have no idea what to do now.

https://www.realtek.com/en/products/communications-network-ics/item/rtl8111f

Symptoms:

1. It take too long sometimes to go up on boot. I have several gigabit cat6 cables. Same symptoms on all of them.Same symptoms connecting with other devices too.
2. Can get it to work above 100BaseTX - half-duplex.
3. Sometimes, when it goes up, the speed is too low. I can't get pass to ~2Mbps with internet speedtest tools. I even created a script to when that happens. Works like a charm, but it isn't a solution. Even so, it won't go above 100BaseTX - half-duplex.

The script basically drops down the interface, rise it up again and test the connection pinging some internet host, in this case, Google's DNS.

#!/bin/bash
re='^[0-9]+$'
while :
do
    ifconfig enp1s0 down && ifconfig enp1s0 up
    sleep 5 &&
    output_ping=$(ping -c 1 -W 0.4 8.8.8.8 | head -2 | tail -1 | cut -c47- | awk  '{ print $1 }' | sed -e 's/\.//g')

    if [[ $output_ping =~ $re ]]; then
        /usr/lib/anbox/anbox-bridge.sh restart
        break
    fi

done

My system is using r8169 drivers:

Answer 1

You probably need the proprietary firmware matching your device.
