Having searched the threads, I suspect I know the answers that I will get but wanted to ask for your feedback anyway. I am in the process of making some changes to my home network.

Current set-up:
Comcast Modem, not providing wireless routing nor dhcp....basically internet connect only.
NetGear Wireless router providing two wlan's...(24 and 5 g) and serving dhcp
Unifi A/P access point (24/5g)
12-13 wired nodes some home run back to closet some connected to mini hubs...
8 port switch (monoprice cheappy) in main wiring closet
2x 4 port hubs (too lazy to want to run wires back to central spot)...

Future Set-up
Comcast Modem as above
16 or 24 Port Gigabit Switch
Net Gear Router (as above)
UniFi A/P
12-13 wired nodes (home run back to closet, going into new swtich..
eliminate mini hubs

Questions:
1) Currently I connect modem to Net Gear wireless router. Is there any downside to connecting Modem to Switch, Switch to NetGear Router?
2) Is there any upside or downside to eliminating the mini hubs? The minihubs are all gigabit, I was just wondering if the spaghetti of wires going every which way causes bottlenecks.
3) Would my wLan work better if I replaced my netgear router with another Unifi A/P and allowed the modem to be the router? I would have to think handoff between a/p's would be better but are there any other advantages?

Thanks for your help!

1) That will not work. At all.
The sequence must be Modem->router->switch and devices.

The modem talks to one and only one device, either a router or a PC...

2) Doesn't matter

Thanks Mr. Moderator for your reply. I gather if I set my comcast modem to become the router and then set the netgear up as an access point only, that I could centralize all connections into the new centralized switch? In so doing the only thing I might accomplish is "neating up" my wiring closet. No other advantages gained?

Correct.
Easier maintenance and cleaner wiring.
No performance change.

In residential equipment, the 'router' is what does most of the work. DHCP, WiFi, etc.
The modem simply translates the signal from the ISP into something a router or PC can use. And it only talks to one device.
A switch is used to just provide more physical ports for more hardwired devices, or to provide easier cabling.
And in most residential equipment, this is all in one actual physical (plastic) box.

For instance in my house...
If I wanted to provide 4 or 8 RJ-45 ports upstairs (router downstairs), I could either...
Run 4 or 8 individual wires upstairs. PITA and ugly.
Or run a single wire from down to up, and use a switch to distribute to the rooms upstairs.
