I know this post was 3 years ago, but I have the same question o this. I just installed Maxis broadband, they gave me latest wifi6 router (black colour with stand), but I prefer to use Asus latest wifi6 router. This Asus router does not come with rj11 port, so what I need to do is just connect lan3 Asus router port to Maxis router wan port? how about Maxis broadbank acc? Shall I setting it on Asus router and disable it on Maxis router? The Maxis phone acc setting remain on Maxis router? Pls help me as I prefer Asus Technology and it air mesh system.
