The configuration doesn't match the PDF in the original post - routing cannot work if you have the same subnet (192.168.1.0/24) for both the LAN on bridge1 and WAN DHCP address from the Zyxel.
The wireless is not working as it has not been configured - default is station, you need to set the mode to make it an AP, plus country, SSID, security, etc.
