Eu também tive esse problema. Eu criei um pequeno script que irá lidar com esta ordem e também automatizar todas as configurações que você fez manualmente.
Você só precisa instalar dnsmasq
e hostapd
.
Não ative ou desative nenhum serviço. Será cuidado.
eth-to-wifi-route.sh
#!/bin/bash
# Share Eth with WiFi Hotspot
#
# This script is created to work with Raspbian Stretch
# but it can be used with most of the distributions
# by making few changes.
#
# Make sure you have already installed 'dnsmasq' and 'hostapd'
# Please modify the variables according to your need
# Don't forget to change the name of network interface
# Check them with 'ifconfig'
