Was working, now can't connect to WiFi
-
Duet 3 mini 5+
Initial setup was nominal, except for failing to setup a static IP address, so it took me a minute to find it if I power cycled my router. Using a Mac and Serial Tools to connect, then DWC.
Worked fine for a bit, was able to get the printer configured, stops calibrated, heaters, etc all working as expected. Once or twice lost WiFi connectivity, but power cycling the printer fixed it, then a couple of times had to plug in the USB cable and use M552 to turn on the WiFi for it to work.
Now it refuses to connect to WiFi, antenna is secure and undamaged. Network is fine, other devices having no trouble. I can connect with Serial tools over USB, but I keep getting the "WiFi reported error: no known networks found" followed by WiFi module is idle.
I've tried all the iterations of M552 to turn it off and on, have tried M587, M588, and M589 to refresh the network parameters, but nothing seems to work.
Where from here?
-
Can you share the results of M122 both when it's connected to wifi and when it's not?
-
Give me a minute and I'll try it connected to USB.
I can't do connected to WiFi since it will no longer connect.

and to be clear, I've repeatedly used M552 with the S and P parameters for the SSID and password, and they worked fine until they didn't
I've also tried using M588 to delete the network and attempt to replace the parameters again with M587 (as well as M552)
If it means anything I think the last thing I tried to do before it quit working was use the M552 with the P, S, and I parameters to fix an IP address so I didn't have to sniff the network every time the router changed it.

Can you use this procedure to update your firmware?
https://duet3d.dozuki.com/Wiki/Duet_3_Mini_5plus_Firmware#Section_Updating_firmware_via_USB
If that doesn't help, send M997 S1 to reflash the wifi server firmware as well. You may need to first manually place the wifi server bin file onto the SD card in a new folder called
firmwareon the root of the SD card if it doesn't already exist as that is where it will be looking in 3.3https://github.com/Duet3D/RepRapFirmware/releases/download/3.3/DuetWiFiServer.bin
-
I've tried that now 3x. Can connect through serial as before, but no WiFi.
Removed MicroSD card, placed in computer and manually replaced the DuetWiFiServer.bin file 3x (twice on a Mac, once on a windows machine for grins) but M997 returns an error:
Error: M997: File 0:/firmware/DuetWiFiServer.bin not found
The file is in the sys directory, where I found it originally.
Quite frustrated, was chasing down the final hardware details and now can't run the printer.
I do have a Pi 4 available, should I just try that and give up on the Duet WiFi?
-
my bad, just realized it was in the wrong directory. moved it and now updated, but same problem: no WiFi connectivity
It was working fine until it wasn't, network is fine.

Try again.
What error do you get when you try to enter the SSID?
What do these produce?

M552 S-1
M552 S0
M552 S1
M588 S"*" -
All of those are in the above messages, but to recap:
M552 returns "no remembered networks"
M552 S1 returns many, many lines of no network available
M552 S0 works as expected
M588 S"*" erased all of the networks as expected, but I cannot add the SSID and password back. Have tried dozens of times (literally)
-
I did get it to work briefly (just now) while connected to serial (I've been doing the exact same thing dozens of times for days without success) but its still wonky. the WiFi will hook up while I'm connected to serial via USB, but I lose it and it won't connect if I unplug the USB and then power the board up normally.
I know documentation says to not use USB and an external power supply at the same time, but I did try briefly to get the WiFi going on USB, turn on the printer, and unplug WiFi.
This worked until I rebooted the board, and no connectivity after that. Got it going again with USB, but can't power cycle without losing connectivity
-
So does it have a saved SSID now or not?
Does your config.g have a M552 S1?
The last test would be to see if it will run in standalone WIFI access point mode.
-
Yes, it seems to be working now. I have no idea what I did differently, which bothers me a bit because it worked fine when I first configured it, then after a week quit working, and now it’s working fine as far as I can tell.
I haven’t done anything differently, but I will watch it for now. If it quits again I’m just going to plug it into the pi or start over with a different board.
-
Well if we can identify what's wrong or if there is something wrong and it's under warranty you can get it replaced.
-
I'm having this same problem.
I can save and forget networks as long as the wifi module has been set to active with m552 S0, but not with S-1 or S1 modifiers. When I try to check the status of the wifi module with M552 by itself, I consistently get "wifi module is changing modes" until there's an SPI timeout message like the one at the bottom of the excerpt below.
I've successfully reinstalled wifiserver.bin twice (i'm doing this over USB with pronterface and a 24vPSU for the board), but this has yielded no changes in anything. If I just let it sit, it'll eventually give me a bunch of these in a row:

I know it's not a poor signal issue, as I've tried within a foot or two of the router.
Here's my m122 if it helps:

That's normal.
The M587 command will fail if the WiFi module has not yet been taken out of reset. So if the WiFi module has not been started, send M552 S0 to put it in idle mode first.
