Board not connecting to Wifi: no know networks found
-
Hi, this is first time trying to connect to a Duet boards, but I have been trying for several hours and I feel like I am running out of ideas. For context, the board is a Duet Wifi 2 and it is already connected to a printer. I have seen the printer running before, but I have no experience running it and the printer has just been sitting on a shelf during quarantine. I am connected to the printer over USB. I am using YAT. I can toggle the Wifi module with M552 S0 and M552 S-1. Running M552 reveals the wifi module is idle. I can run M587 S"Network" P"Password" and it responds "ok". Earlier I cleared all the networks and was able to add this one back on successfully. When I input M552 S1, I get:
ok<LF>WiFi reported error: no known networks found<LF>WiFi module is idle<LF>
I am not really sure where to go from here. My network is at 2.4 GHz. My firmware is version 2.05.1 and my WiFiServer is version 1.25. I do not think the board itself is faulty, but it has not been used in a few months. Any help is appreciated.

Wifi server is 1.25?
Can out send m122 and post the result?

M587
whats the output of just M587? does it include the SSID you added, and is the network a 2.4Ghz network? Any special characters in SSID or password?

The output for M587 is:Remembered networks:

Looks like I was mistaken. The WiFi Firmware is actually 1.23

I'd try without the

Alright, I'll try that. It's not my personal network so I'll have to contact someone to change it, which may take a while. I'll post back here if it does (or doesn't) work

You may want to try using a macro to add the wifi network. That can avoid any capitalization changes that the USB terminal may do. It's also easier than having to type it a bunch of times.
Something like this saved as a macro called addwifi and placed in the macros folder. Then you can send
M98 P"addwifi"to execute it.; Add default wifi network ; M291 R"Add default WIFI network? Y/N" P"This will add duetwifi access point." S3 T10 M552 S0 ; Disable network module G4 S5 ; wait 5 seconds M587 S"NETWORKNAME" P"PASSWORD" ; Add duet wifi SSID to remembered networks list G4 S5 ; wait 5 seconds M552 S1 ; reenable wifi module M291 R"duetwifi SSID added." P"Check console to verify IP address."Since the network is not under your control, you could use access point mode to test that the wifi module is otherwise working.

@Phaedrux
I am trying access point mode currently
I input: M589 S"NetworkName" P"Password" lnnn.nn.nn
It returns: M589: Bad or missing parameter
The WiFi module is Idle. I think that the part I am messing up on is the IP. I am pretty new to this, can the IP be just any random numbers, or is there a format it has to follow? -
Yes you will need to specify an actual ip address.
192.168.0.1 would be suitable.
Example command: M589 S"DuetSSID" P"password" I"192.168.0.1" C1

@Phaedrux
It worked! Not a permanent solution, but it’s good to see some progress. I’ll stil try to get that password changed. Thanks for your help -

AFAIK the ! $ @ symbols should be OK in a password. OTOH, many GCode sending programs force all characters to uppercase (which will mess up any lowercase characters in the password), also I don't think the WiFi firmware supports accented characters.

ah, they were in a warning for SSIDs in the docs, but that doesn't apply to the password then?
Given OP's output from
M587showing mixed case and no special characters I presumed the issue would be the password, signal strength or frequency band (or could technically still be SSID case sensitivity I guess) -
I was sending the gcode commands using YAT, which I believe can send lowercase characters.

Yes it does, that is why I asked you for the output of M587 with no paramters. It shows the SSID is stored with both upper and lower case so we know you're not using a upper case terminal.
Can you confirm the network is 2.4GHz and that the case is exactly as shown in M587. Duet does not support 5GHz.
-
I am pretty sure the network was 2.4GHz. I’ll double check with the admin when they change the password. Because of Covid restrictions, it may be a while before I am actually able to test anything out.
