How to turn on the internet on wifi and map all lan ports?

i hope you have followed the previous guide to setup basic router on mikrotik. Now you would configure WiFi interface and map all lan ports.
Wireless -> interfaces -> Enable wlan interface and Change settings in interface.
Mode: ap bridge
SSID: My Router Name
Bridge -> Add bridge
name: bridge1
Bridge -> Ports -> Add port
interface: wlan1
bridge: bridge1
Bridge -> Ports -> Add port
interface: wlan2
bridge: bridge1
Now you have configured the wireless LANS. Now you need to setup password for secure wifi access.
Wireless -> Security Profiles
Edit default profile. Select “WPA PSK” as authentication type and  change the password in “WPA Pre-Shared Keys“. Once you have done that go to Interfaces tab and select this profile for both wireless interfaces.
Bridge -> Ports -> Add port
interface: ether2
bridge: bridge1
if you want remaining ports to identical and share internet
Bridge -> Ports -> Add port
interface: ether3
bridge: bridge1
Bridge -> Ports -> Add port
interface: ether4
bridge: bridge1
IP -> DHCP Server -> change dhcp server interface
Interface: bridge1
