Was working, now can't connect to WiFi

Not sure where I would look or what it should say,

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"
Example 1:

Slowest loop: 1.27ms; fastest: 0.00ms

WiFi -

Curiously tho, I can turn on AP mode and get into DWC that way. 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.
