I could be wrong but my take on a mesh system has always been that you use mesh to provide wifi where don't have a close enough ethernet drop to add a wifi access point. The mesh network passes the wireless from point to point, expanding the distance you can obtain wifi.
If you have the ethernet drops available, you don't need mesh. Just get more wifi access points.
This isn't accurate at all. Lots of people should read this post...
Mesh is when two more more access points work together to "move you" from one to the next, without you disconnecting, all using the exact same SSID. So when you walk from one end of the structure to another, the mesh system "moves you' without disconnection across the various access points working together in said mesh. Using this method, the mesh system always knows which access point you're closest to and quickly moves you to it as necessary.
So if you had 3 access points in a line #1................. #2 ....................#3.....
As you walk from #1 to #2, for example, the mesh system will auto-move you to #2 as soon as your closer to #2. That's mesh. If you're not in mesh, you could be standing between #2 and #3 before #1 finally gets weak enough on your device to disconnect you, and then connect to the next closest... meaning you have a weaker signal because you're still tethered to #1, despite being far away when connecting to #2 or #3 would be more logical and a better connection with faster throughput.
Mesh, however, also has a heavy processing overhead for the access points themselves - which comes into effect when you using Mesh in a business or place with heavy traffic... then Mesh can really slow down your network depending on said load.
IF YOU DO NOT use MESH - but you still program each access point with the same SSID name... then what happens is as you move away from the one you're actually attached to, eventually you'll reach a bandwidth threshold and you'll disconnect and then re-attach to the one that's now nearest you. This causes a minor disconnection that you may or may not notice. (Example, you at home on a tablet device - wouldn't really notice. You as a restaurant server carrying a point of sale handset moving around the restaurant that constantly gets their connection broken, would totally notice and have issues).
ALSO - Not all access points have direct connections, and mesh has nothing to do with it. Example... you could have all 3 access points with ethernet connections... which is ideal. But you could have a situation where you have one or two ethernet wired, but one that's an "extended" access point who's job is to be unwired but connects to one of the hard-wired ethernet access points and "extends" the connection via amplification and also still uses mesh. Not ideal, not the best, but can work for many situations/homes.
