Wifi not connecting
-
When connected to a USB terminal, send M98 Pconfig.g and see if you're getting any errors on execution.
-
I really want to thanks both of you guys for taking the time to help.
@Phaedrux M98 Pconfig.g returned no errors.
@SIam I flashed fw 3.0 but still got the error. I reflashed wifiserver 1.23 but still couldn't connect. Finally I deleted my known network and reapplied it and this time it connected no problem.
It's a strange one as it was connecting fine with 3.0-beta3 until it stopped for seemingly no reason.
I think I'll stay with 3.0-release for the time being.

This thread deals with something similar, suggested bad wifi module. But maybe you can verify you've tried the suggestions there

https://forum.duet3d.com/topic/10139/failed-to-add-ssid-to-remembered-list-duet-2-wifiI was thinking that was the problem, but then it worked in AP mode so that cast some doubt in my mind.
Anyway after multiple re-flashes and networks deleted and added it has started to work again.

Maybe the firmware is revolted by being on a clone.

@Phaedrux Possibly
I was upfront about using a clone and therefore appreciate the help given.
-
The majority doesn't care one way or the other, but it's nice to know as component quality can be a factor.
I haven't studied the protocol between the esp and the duet, but I imagine AP mode is simpler than returning a list of networks so wouldn't be surprised if it worked despite failing at STA mode.
Silly question, but are you sure the wifi firmware upload was a success? If you have serial access maybe worth downgrading and upgrading to be relatively sure it works?

Yeah I'm sure. I was actually running the previous version when the problem first appeared. I found a post that said it could be caused by the fw versions getting out of step - so upgrading to 1.23 was one of the first things I tried.

It might be worth measuring the voltage on the +3.3V rail, to see if it is within tolerance. The WiFi modules are fussier than other chips on the Duet WiFi about the supply voltage they get.
Is it the same ESP-12S module that we use on genuine Duets, or is it one of the older ESP-12 series modules?

It's the ESP-8266MOD.
It's been rock solid for a year before it played up. Now that it's working again and has been stable for the last couple of days, I'm reluctant to start poking around with a probe. It would be just like me to short it out.
If it plays up again I'll bear it in mind to check.
