Do I need a mesh network?

I have moved to a new apartment recently, and am yet to get an internet connection. I will be applying for Airtel Xtream fiber connection, 200 mbps plan. The layout of my apartment is as below:
12.png


It is not exactly to scale, but it should be within 10% of the actual dimensions. Now, it seems that the site marked 1 is the most accessible site for the fiber to be pulled into the house. I can place the ONT device and router over there. The TV in the hall should not have a problem accessing the network. However, I need good wifi in the rooms marked 2, 3 and 4.

1. Is there any possibility of a wifi extender helping me provide good wifi signals in these places? I have an Archer C7 with me. I need to buy extenders, if they will be suitable for my use case.
2. Would a mesh network be more appropriate in this case? If so, any suggestions on how many nodes will be required?
3. Would things be easier if the fiber is brought into the house through room 3?

The entire apartment has a floor area of around 950 sq.ft. Please suggest.
 
Go for a mesh for seamless movement across the house, extenders to my knowledge are not as seamless as MESh. you will need a two unit mesh One located next to the airtel router and another in room 3. if you would like to have obe more you can keep it room 2 also.

If the ONT device has a Network port you can directly connect your MESH to that and dont need any more routers etc.

Update:
My Airtel Xstream fiber connection is in place, and the ONT device is an AOT5221zy, which supports WiFi6. It has been installed in location 1 in the layout given above. I am getting full signal strength (>95%) in room 2, and minimum 70% strength in room 3 (wifi strength was measured using some wifi analyser app on an android). Rooms 1 and 2 are getting full speeds of around 200 Mbps, while room 3 gets more than 150 Mbps consistently. These are better than what I expected.
Room 4, though, seems to be getting only around 40 to 50% signal strength, and the speeds are only reaching a max of around 80 Mbps. This is the room where my work set up is, and I would prefer if it receives the maximum strength and speed. Should I go ahead with the mesh plan?

If you only need another router in one room, hold off on mesh.
You said you have an archer C7 right?
Check if it has easymesh support.
If yes, just get another cheap router/extender with easymesh support and install it in that room.

I have a similar setup with my AX53 covering 3 rooms and an AX10 covering the farthest room which is my home office.
Connection is seamless since both routers are from TPLink (although easymesh does work cross vendor, not sure how well though).
My backhaul is wired though. Wireless might need some adjustments regarding placement.

Oh and keep in mind, only the main WiFi connection is meshed with Easymesh. Guest and IoT networks aren't.
If you need those as well, you'll have to go for a ground up mesh solution like their Deco series.

You can also talk to Airtel and see if they have any mesh extenders for your ISP router.
Since you only need one, this would be cost effective as well.

Will check out both the options that you have suggested.

But it is wifi 5. Would that be a downgrade since the ONT is wifi 6?
Ideally, no.

The major difference between 5 and 6 is managing load congestion. Since both use the same frequencies, and assuming you don't have multiple client devices loading the router at the same time, I don't foresee it being a downgrade.

That said, you can always just install the C7 and give it a test to check how it works in your setup.

Can a single deco model be used as a wireless AP/extender/repeater which connects to main non-deco router via wireless?

Yes my Deco X50 has AP mode which works with another router but you lose out on seamless handovers and having the same network SSID in all areas in the house, in which case why spend on the deco; many other cheaper options are there.

Ideal is two or more decos spread around and interconnected with Ethernet cable.

As I understand, even if multiple Deco units are used as APs they still retain seamless handover feature within their own deco based network. I mainly wanted deco to extend guest/IoT network too unlike easymesh which only extends main wifi network on another floor. I can also do this by using another wds capable router by connecting it to main router's guest wifi on other floor but it will make more wifi networks on the floor so kind of messy & that's why looking for a single deco based solution.

AFAIK the Deco will not wirelessly connect to a non-deco router. It can only wirelessly link with other Deco units.
The first/main deco can be linked via ethernet to non-deco router but in that case if one chooses the working mode of deco as "router" then that will create another ip range network (say 192.168.2.x) which won't be accessible by the ip range network of main router (say 192.168.1.x) deco is connected to. If first/main deco is connected to main router via ethernet with working mode set as AP then it creates a wifi network based on same ip range as main router but then the deco wifi network won't have seamless switchover with main router wifi network but most likely if further deco units are connected to main deco as APs then seamless switchover should work within that deco wifi network.
 
TP Link advertises that Easymesh and Deco are not compatible systems and so getting another EasyMesh compatible router may be the most optimal solution. Else, you might need to change your host/main router to a deco mesh compatible system. Other option might be to an ethernet wire for your work setup in room 4 and rely on Wifi only for casual/mobile workloads.
 
if further deco units are connected to main deco as APs then seamless switchover should work within that deco wifi network.
This is how I have set it up.

Two ISP routers come into a failover / load balancer router (TP Link ER605) which directly connects to a POE Switch (TL SG1016PE) and then all the Decos connect into the switch by POE with one deco being designated the main one.

I connect to wifi only via the decos, this way I use the deco's mesh wifi as well as iot & guest.
