WiFi reported error: network scan failed
-
Thanks for responding! Access point mode seems to have issues. I've tried a second reflash without luck. Details below. Thoughts?
Lights
You asked about lights. I believe I was getting a blinking blue light on the WiFi before the March 14th reflash, now no blinking (either before or after 2nd reflash).
Status after boot (prior to 2nd reflash)
Still in this state, repeating every couple of seconds:

Otherwise status seems same as prior to first reflash (although I only flashed WiFi that time, M997 S1).

Also, just to be clear, the printer will print fine when supplied a gcode file on the SD card.
-
Before enabling access point mode did you configure the SSID and password, etc with M589?
https://duet3d.dozuki.com/Wiki/Gcode?revisionid=HEAD#Section_M589_Configure_access_point_parameters
When and where did you purchase the Duet?
-
@Phaedrux I did not configure the AP; I'll do that and report back.
This Duet was purchased from Filastruder around April 29, 2017. Been working well this whole time, thousands of hours of prints.
Are those SPI errors normal?
-
Let's see how AP mode goes. The SPI errors are normal in that they are a thing that can happen. But they are not ideal. It's possible that the wifi module is failing.
But try AP mode and try adding your SSID again.
-
TL;DR: AP mode works ok. Console output below (inputs hand-inserted as best I can).
I guess this implies that something about my router or the overall environment changed. I'm going to rebuild the router (little GL-MT300a box) and also see if I can get it positioned even closer to the Duet. I'll follow up if it turns out that I cannot get it to connect after the rebuild.
Any other thoughts?
Thanks for the help in debugging!

Well at least we know the wifi module is working.

@paralepsis I am having the same problem, except using the access point mode is not helping. Did you find a fix?
-
@tylersuard please start your own thread with your board info and M122 output
-
@tylersuard in my case I thought that the AP was fine, but in fact it had died.
-
@paralepsis The AP died, how did you handle it? Did you get a replacement from Duet, or ...?
