Core One+ connects to weakest wifi signal in mesh setup  

RE: Core One+ connects to weakest wifi signal in mesh setup

My mesh wifi is TP Link Deco. I can specify which router each of my devices should connect to. Also if you can hook up your mesh via backhaul (connecting all routers via ethernet) all your nodes will get very strong WiFi range.

Hi,

I have a mesh wifi network setup at home. The Core One+sits in a spot where one of the wifi routers has a very weak signal, but the other is less than 3 meters away.

Unfortunately it connects to the weak one, and this leads to it basically not working through prusa connect, until it eventually loses connection to the far away wifi router completely and with a bit of luck it then connects then to the other closer router and it starts working.

Is there any way to tell the printer to prefer the strong wifi signal to connect to? Or specify a wifi mac address or some other way i can make it do the useful choice and not connect to the weakest signal wifi it can find?

If you can, either move the mesh router further away (counter intuitive but is works) or use and ethernet cable and connect it directly to the mesh router (assuming it has an ethernet port).

How would that work? I can see that, without an Ethernet backbone, a purely wireless mesh node will use part of its bandwidth for the uplink. (If it is not of the more expensive kind with a separate wireless channel for that.) But how would an Ethernet backbone improve the signal strength (range)?

It can actually help, because some routers (including mine) use 5gh band for interconnect, and the other band (was it 4gh?) for the devices, 5gh can have higher bandwith and has different characteristics when it comes to passing through obstacles. 

So, yes, it *can* help signal strength if your mesh routers don't have to reserve one wifi band to talk with each other, and let devices (who are able to) use that band too.

Unfortunately this is irrelevant for me, because my wifi routers *are* all connected via ethernet, and I very much doubt that the tiny ESP32 ethernet board can even do 5gh wifi.

Already the case. my routers are connected via ethernet, and the signal strength is no issue. The coverage *has to* overlap at some point, or i would have areas in the house without wifi, and it is physically impossible to have a strong signal from ALL routers in ALL areas of the house. 

If that was the case I wouldn't need a mesh of several routers in the first place.

Well my network is Triband, (2.4, 5, and 6GZ) And I can login and specify which node. and band to use for each device. I actually had to configure my 2.4gz band with a simpler password with no special characters to get my @#$% Buddy 3D Camera to connect after upgrading to CoreONE+.
