I have 4 RB951-2n devices, all running ROS 5.24.
Area I want to cover is an office in an apartment building. There are many APs (both weak and strong) in the building, using various channels, and I suspect they are mostly set to "auto" channel (so the term "least used frequency" is of little relevance here, I think).
Since our office is small, you might wonder why I have 4 APs. It's a fair question: we have 20+ wireless devices, most of which are transferring data at any given moment.
This is the layout of the office (pardon my humble drawing skills):
Red triangle is where router and rest of network equipment is located. I've tried to represent relative signal strength around the office: green would be "full" signal, in orange area it drops to around 2 bars. I know it's not exact, but it's just to get the idea of signal how signal spreads in our office.
It is not possible to pull cables around, so what do you think, which of following two configurations make more sense?
1. 4 APs connected directly to a router, all placed where red triangle is, configured with same SSID/security settings, but on separate channels (1,5,9,13), so that clients connect to any of these four, thus sharing the load.
2. placing AP1 where "router" is, and AP2 at "location 2" (see image). Both APs share SSID and channel number (or perhaps they should operate on separate channels, too?). AP1 and router are connected via cable. AP2 and router are connected via AP3+client bridge (AP3 is on the router side, client is on AP2 side) which operates on separate channel with separate SSID naturally, and acts as a bridge. This configuration should (at least in theory) allow clients in closer proximity to either AP1 or AP2 to connect to them, thus sharing the load between two APs, while bridge would not be impeded by clients, so it should have best performances possible.
