start hostapd deamon:

hostapd -t -d -P /var/run/wlan0.pid /etc/hostapd/hostapd.conf

install dhcp server

install dhcp server package:

pacman -S dhcp

configure dhcp server:

start dhcp server on wlan0 interface:

dhcpd wlan0

iptables rules

set iptables rules for sharing internet to wlan0:

cat > /usr/local/bin/sharenetwlan << EOF
#!/bin/bash
iptables -t nat -A POSTROUTING -s 192.168.10.0/24 -o eth0 -j MASQUERADE

set permissions to script:

chmod +x /usr/local/bin/sharenetwlan

execute script:

/usr/local/bin/sharenetwlan

speed test

install iperf3 on server and client:

pacman -Sy iperf3 --noconfirm

start iperf3 service on server:

iperf3 -s

on client connect to server using iperf3:

iperf3 -c 192.168.10.1 -p 5201

you should see somehing like this:
