FIRST BEFORE YOU DO ANYTHING.
Go to the app store on your mobile and download and install "WiFI Analyzer"
Check what devices in your area are using what channels, Go into setup on your Router and set it to use a Free Channel and lock it to that, for 2.4 GHz use dual Channels this improves the Signal Quality Long Range. 5.0GHz for device that can use it. Found turning on the extra channels upset it a lot.
Which is why I chose to add my own WiFi routers, from Hub 1, Below is my current setup I have now been using for about 2 years, since AC WiFi was available.
Personally I found Modem mode fouled everything up.
Due to the limited range of the Supplied Hubs WiFi, I have always used my own routers.
I have 1x 2.4GHz WiFi channel open on the hub for checking purposes.
From the Hub ports I run Cat5e cables:-
Port 1 - Direct to a Netgear 10 Port Gigabit switch in the lounge,
Connected to Netgear R8000 Nighthawk WiFi Router 2x 2.4 GHz 3x 5.0 GHz
Other ports to other devices as required
Port 2 - 20 metres Cat5e to the small bedroom connects to a Netgear 10 port Gigabit Switch
Connected to this is a Netgear R7800 Nighthawk WiFi Router 1x 2.4GHz 2x 5.0 GHz
Connects to Gigabit Devices
Port 3 - 20 metres Cat5e to the small bedroom connects to a Netgear 10 port Gigabit Switch
This switch connect to legacy 10 - 100 bit devices, including Network Printer.
Port 4 Connected to the LG TV
The Netgear Nighthawk Routers self configured when they were connected into the network.
By having this many WiFi channels I can have 8 devices each connect via a separate channel. Down fed via cable to the main hub & the internet, this reduces interference between devices. Also if you have channels available you could set these to separate channels to give some separation to reduce interference.
The idea of using extenders all using the same network, which can then cause interference to each other, then you might have 6 devices trying to communicate with the main hub via WiFi at the same time. Now you start to realise when your problems might be.
nb it might say newbie, Been building PCs since 386SX25 late 80's
My network is VM connection 200mbit VMDG 480 Gigabit routers Netgear Nighthawk R8000 & R7800 2 x cat5e cables to work room, have 3 gigabit switches at key points. Routers give me 3x 2.4 & 5 5.0 GHz WiFi channels - one for each device.
