wifi works fine with latest firmware. I was using the latest from the config site https://configtool.reprapfirmware.org/Start.

if i would have known there would have been issues, i would have purchased the wifi instead ..

sorry for late reply! I had the schematics up to double check connections to ensure everything was where it needed to be. the endstops never worked correctly despite 3 attempts at configuration. the config file was identical (b/t the wireless and maestro) I am currently printing with the wireless in fact.

as far as the maestro, before the diag led came on, it would load the interface a few times. It wouldn't consistently load after reboots. I had the correct ip address configured in the config file.

I am using the wifi because the maestro won't load and has a "diag" led lit. I am using the default ender 3 pro settings even though I have the non pro.

okay, so I had the web interface working... but the board would not home properly. This was all working on a D2 Wifi board, so you can see this is very frustrating swapping in another board and it not working properly. when i came back (away for holiday) and tried to diagnose the issue.. the red diag light came on and the web interface stopped pulling up. I went through the steps https://duet3d.dozuki.com/Wiki/What_to_do_if_your_Duet_won't_respond. including using yat to try to connect, although it would not give me an "ok" prompt after submitting a command. i honestly just want this thing to work like the wifi did. it was simple and smooth

okay, thanks for the tips. it was the interface w/ router.. I had an old hub that I hooked it up to and it works great. I have the Linksys WRT 1200 AC... not sure if there is a way I can configure the connection speed with the current firmware. if there is another way other than what I have, let me know.

sorry for late reply, I thought I got email notifs via the site.

I have had the D2 Maestro for 3-4 months sitting in the box. Just yesterday got to setting up the board with an Ender 3 (non pro). So far I have determined that this is not a cable issue, nor an sd card issue... as I have swapped both out for known working parts. Hooked up to Linksys wrt 1200 ac router. no activity lights on the router, nor on the board by the Eth connection. I did hook up board via usb to lappy and set up the network. In YAT, says network enabled. When I try to connect to web interface, nothing... which isn't a surprise since activity leds are not appearing. not that it matters, but in the router admin, there is no device for the board showing.

also, I have noticed that the network ip I set will not save... as it resets to 0.0.0.0 after no power.
