Hello guys I'm facing an issue by setting up my deco M4 as access point connecting to my existing router. 

Question1: which port do i have to plug onto my router if i wish to convert my m4 as an access point?

Question2: i will start setting up my m4deco in the app and following all the instructions, however when it comes to detecting the Internet stage, the deco doesn't seems to be able the internet and the light will go solid red and says can't find the network i created, sometimes it will just reset and start over. 

Question3: is it possible for me to setup my m4 as an access point before setting up a network? Everytime the network can't be found or Internet couldn't be connected, even if i switched it to access point mode, it will reset to router mode automatically.

Hope to hear from you soon,

Thank you, Simon
