Hello, Irineu. bela is right. For your notebook to function as a wireless access point, you need hostapd plus a dhcp server. There are different dhcp servers you could choose, I happen to like dnsmasq. If you want to try dnsmasq, after installing the dnsmasq extension ($ tce-load -wi dnsmasq) you can use my script below. Just make sure to change the two variables as appropriate for you, then run the script as root.
#!/bin/sh
# user variables
lan_if=wlan0
ip_stem=192.168.10
# set lan_if ip address
ifconfig $lan_if $ip_stem.1
# create dnsmasq.conf
echo "listen-address=$ip_stem.1
dhcp-range=$ip_stem.100,$ip_stem.200,255.255.255.0,24h
dhcp-option-force=option:router,$ip_stem.1
dhcp-option-force=option:dns-server,$ip_stem.1
dhcp-option-force=option:mtu,1500" >/tmp/dnsmasq.conf
# start dnsmasq
dnsmasq -C /tmp/dnsmasq.conf
