HELP! Can't log in to both machinesWIFI passwords!?

Phaedrux

So I seem to recall from your past threads that you use the Duet in Access Point mode where the Duet creates the network and your laptop connects to the Duet SSID. This is likely what it's asking for as a password.

Can you share your config files with us here?

If you can't recall what the password was for the the SSID, you can simply create a new one.

Take a deep breath. Panic never helps. I'm confident we can get you back up and running.

Here is the information for getting access point mode working:

https://docs.duet3d.com/User_manual/Reference/Gcodes#m589-configure-access-point-parameters

Do you have an M589 command in your config.g? That's where the password is set.

The M551 password is something else and you don't need or want to set one there right now. So if your config still has that, remove it.

@fcwilt Nope, never ever have had.

Always worked fine til my laptop wifi borked.

I tried another different laptop and it also wanted network security key for both machines this morning, no idea if this is usual as I don't think I have tried to connect before with another.

I may have had a key (?) or not, either way, need to refresh both duet boards, ascertain key and get them running asap.

Have done the big print I needed but wanted to do a load of info sheet holders today on the point6...

The Configuration for the Wifi is not stored in config.g but in the wifi chip.

You will need to do the following:

a) connect to the printer via serial console
b) Set a new password for the access point mode using M589
c) save the new password somewhere safe for reference
d) enable the access point mode using M552 S2
e) use the password set using M589 when your computer prompts you for a network security key

Let us know how this works out.

@fusedeep you are running M552 S2 on both machines at the end of config.g. This puts both machines in ‘accesss point’ mode, so the laptop connects directly to the WiFi of each machine. At some point you will have set this up with M589. In that command you specify the SSID (the name of the network) and a password. It is this password that your laptop appears to have forgotten. If you didn’t write the password down, you need to connect via USB, and send M589 with SSID and password to set up the Duet access point. You can also do this by writing the commands into a macro called runonce.g, which will run and then delete itself at startup (so make a copy in case it doesn’t work). See https://docs.duet3d.com/en/User_manual/Machine_configuration/Networking#configuring-duet-in-wifi-access-point-mode

The commands in a macro would be:

M552 S0 ; sets WiFi to idle
G4 S5 ; wait 5 seconds for WiFi to turn off
 M589 S"DuetSSID" P"password" I192.168.0.1
G4 S5 ; wait again
M552 S2 ; enable access point

Hi, thanks for the information.

Can i do this directly in the sd card edit?

Yat is borked and putty playing up (I am not an IT expert either, consoles freak me out when they don't work).

@droftarts

I have 2 duet running. Should the ssid label for each be different, Yes, only use ad hoc.

@droftarts

My gut feeling is this has nothing to do with M589 etc.

It never had one and my android phone won't connect with the M589 password either.

It's something else imo.

Yes. Create a text file with the Gcode commands I listed earlier. Save it on your local machine as "runonce.g". Copy it to the SD card from one of the printers, in the "sys" folder. Return SD card to machine, turn on machine, give it a minute, then try and connect.

Do one at a time, giving them different SSID names and IP addresses (I think, from memory, you gave them both the same IP address before; this could be where it's got confused). The password can be the same for both, though.

FYI: File runonce.g is supported from RRF3.1.0 and later. If this file is present at startup, it is run after running config.g and activating the network, and then deleted. So I hope you're not on RRF 2.x!

@droftarts

But, I have put the M859 code line directly and nothing will connect using that pasword.

What is the difference using a one time widget?

@fusedeep You need to turn off the Access Point (with M552 S0), change the SSID/password (with M587), then turn it back on again. The macro does this for you.

If you're able to do this with a serial terminal (putty/YAT), you don't need to use a macro.

Save the file as a .txt file, then edit the name and replace '.txt' with '.g'.

I have added;

M589 S"DuetSSID" P"password" I192.168.0.1

To my point 6 (with my password) and it won't accept the password.

Nor will my phone.

Or my other laptop.

They keep asking for NETWORK SECURITY KEYS, I don't think this is anything to do with gcode passwords and a fundamental password deep in duet that is either borked or I forgot.

It's a real problem people.

I was nervous about going wifi, and this is exactly why...

I dropped this into macros folder as a g file extension

It does not work.

put it into your /sys/ folder and try again.

Edit: To verify that the macro "runounce.g" was executed, take a second look at the /sys/ directory: the file must have vanished.

droftarts

All fixed now! The WiFi passwords had been lost due to a laptop borking and being rebuilt, so the Duets needed resetting with M589 (there's no way to recover the WiFi password). However, one undocumented 'feature' - WiFi passwords need to be at least 8 characters long. So the runonce.g wasn't working. Once @FuseDeep connected via YAT (which wasn't working on the original laptop, had to use another laptop), he could see the error message, and set a correct SSID and password.

I'll update the M589 documentation to reflect this.
