Hi all, total noob here. need some advice for wireless mesh network setup in my new 4 room BTO flat.
I'm using the TP link deco M4 with 2 wireless router units.
I heard that ethernet backhaul is more stable that wireless backhaul, so I'm thinking of using an ethernet backhaul, with one unit in the living room below the TV and the other one in the MBR. I got the electrician to wire so that there are direct ports from the DB box to to both APs mentioned above.
The setup I was originally thinking of is:
Fiber termination point -> Singtel ONR -> AP1 -> Deco M4 unit
--> AP2 -> Deco M4 Unit
However, based on the first diagram provided in this link:
https://www.tp-link.com/us/support/faq/1794/, it seems that I need to directly wire the 2 deco units together? Or at least get an ethernet switch for it to function in AP mode only
My questions:
1) Do ethernet cables go "both ways", meaning if 1 Deco M4 unit is directly connected to any AP in the house (and connected to ONR), I can plug another Deco M4 unit into another AP and connect its corresponding port in the DB box to the ONR, will the second unit considered to be directly connected to the back of the first, resulting in an ethernet backhaul? (Referring to case 1 in the link provided)
2) Do I need to get a switch or does the ONR already function as a switch as it "splits" the data flow through the 4 ports at the back?
3) What is the difference between AP only mode and router mode?
Would really appreciate some help in the above matters. Total noob at this. Thanks in advance!
