Was working, now can't connect to WiFi

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:
WiFi module is idle WiFi reported error: network scan failed WiFi module is idle WiFi reported error: network scan failed WiFi module is idle WiFi reported error: network scan failed WiFi module is idle WiFi reported error: network scan failed WiFi module is idle WiFi reported error: network scan failed WiFi module is idle WiFi reported error: network scan failed WiFi module is idle WiFi reported error: network scan failed WiFi module is idle WiFi reported error: network scan failed WiFi module is idle WiFi reported error: network scan failed WiFi module is idle WiFi reported error: network scan failed WiFi module is idle WiFi reported error: network scan failed WiFi module is idle WiFi reported error: network scan failed WiFi module is idle WiFi reported error: network scan failed WiFi module is idle WiFi reported error: network scan failed WiFi module is idle Error retrieving WiFi status message: SPI timeout Error retrieving WiFi status message: SPI timeout WiFi module is idle Failed to change WiFi mode: SPI timeout Once the SPI timeout message(s) come, m552 reports that the wifi module is disabled.
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.

Have you been able to verify that the correct version is installed with a M122 when the wifi has connected?

Not sure where I would look or what it should say, but the process was successful according to the console in pronterface

In the M122 report at the end there is a section for wifi
- WiFi - Network state is disabled WiFi module is disabled Failed messages: pending 0, notready 0, noresp 2 Socket states: 0 0 0 0 0 0 0 0 When it's active it would say what wifi server version it's running.

This kind of thing happened to me and part of my resolution dance, along with a big chain of FW upgrades to current, was in discovering that my modem/router had smashed the 2.4ghz and 5ghz networks into one automode SSID. And the Duet doesn't like 5ghz I think. I had to dig into my router config and force the two networks to separate SSIDs, after which the Duet was much better about seeing the 2.4ghz network even after a restart or a few days switched off. Not perfect, but much better.Maybe looking into that could help.
-
@ddxdesign good thinking, but I've got two discrete networks, one 2.4 and one 5ghz.
I tried to post the m122 info that @Phaedrux asked for yesterday but couldn't do it for some reason, maybe I should try again in a moment

@phaedrux here you go, as requested. It will only show idle or "changingmode"

That would be a great workaround if it worked in the config.g file, but the wiki says that's a no-no.

Does it say that? I think it says you shouldn't setup the SSID and password params in config.g, but to enable access point mode you'd just have M552 S2 to turn on AP mode.
Regardless, it's odd that it works fine in AP mode, but not with the router. That indicates the hardware itself is fine and the problem is some incompatibility with the router or settings.
