Duet 2 Wifi will not automatically connect to WAP

Macgyver

This is a bit of a strange one so I am going to post what I am seeing and see if anyone else has seen the issue. Seems the issue only occurred after the upgrade to version RRF 3.4.2. I do not recall it happening on 3.3 although I did not stay there long as I was upgrading to the latest. This is a new build but a known good configuration on other printers.

I have worked through this thread https://forum.duet3d.com/topic/22157/wifi-reported-error-network-scan-failed/8
The problem seems very similar but not quite the same.

when I start the printer I get the following error message on the console
WiFi reported error: network scan failed (50 or so times) then it simply says connected but no IP address appears.

When I run M552 S0 and then M552 S1 it connects not an issue and gives me the IP.

In my config file, you will see additional M552 commands that have been commented out, I tried to not start the network at the beginning of the config file and only start it at the end, Does not matter when I start or stop the network. I have tried stopping (S0) at the end of the config and (S1) to restart it. Still no luck. Will only work flawlessly when I stop and restart the network from the console after boot.

new Build printer from a manufacturer, config files are from them,

The printer will boot up, I get repeated messages but no automatic connection.

Any suggestions would be appricated.

@macgyver any chance you can grab an M122 output so we can see what wifi firmware version you are running?

@macgyver you could try updating the wifi firmware to 1.27 (from 1.26).
I don't think it'll make a difference but reflashing the wifi doesn't hurt.
https://github.com/Duet3D/RepRapFirmware/releases/download/3.4.2/DuetWiFiServer.bin

on a side note, you should always keep DWC and RRF running the same versions as theres always a chance that a fix in RRF breaks something in DWC. version 3.4.2 can be found here https://github.com/Duet3D/RepRapFirmware/releases/download/3.4.2/DuetWebControl-SD.zip
to update both just upload them to the system tab

Macgyver

ok, will do that now, In process of commissioning this printer so want to have it running without an issue.

I will post the results shortly.

Macgyver

HI @jay_s_uk , thanks for the reply

After installing just the Wifi update, Came up with the same scrolling error and then a message connected to the access point, IP address 255.255.255.255,

That was weird because that is a broadcast address. Anyway did the S0 and S1 again and it connected properly. Error is basically still happening.

I updated the DWC as a separate step to help anyone else troubleshoot,

First time I power cycled the printer, Came up perfectly, Connected properly and gave me the proper IP address.
Power cycled it again and back to the same error message.
However, If I just do nothing Eventually it does come online itself. Sometimes takes 2 mins to connect and give me the IP.

So I started thinking maybe there may be some other networks in the configuration that is toying with it. I ran the procedure listed in this Post
https://forum.duet3d.com/topic/9888/how-to-erase-remembered-networks/4

basically the M588 S"*"
I set up my network again from scratch with the M587 and now after 10 power cycles, It seems to be working ok.

If I was to guess what may be going on as you apply firmware versions it may be adding "default" or "beta" networks that it has to scan and see that they are not there before it will move on to the next one. That is strictly my guess but the version of the DWC definitely had the biggest effect.

For me, I just like to try and understand the source of the error but for anyone else troubleshooting this error take @jay_s_uk 's advice and ensure your firmware versions match.
