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

FuseDeep

@infiniteloop I have a screen connected to my big printer.

I have no central router, there is no landline here. only adhoc to printers and a hotspot from phone.

The printers do not use the phone as an adhoc router.

Will try and add gcode to sd card and get printing...

@fusedeep

The printers do not use the phone as an adhoc router.

That's ok, they don't want to connect with the web.

I have no central router, there is no landline here.

So you don't have any router at all? Can I assume that you've set up your laptop as an access point?

I have a screen connected to my big printer.

Can you enter commands into the console from this one?

FuseDeep

@infiniteloop No router.

Both duet boards in use always connect adhoc to laptop, no key needed (unless i entrede a key early on and no lobger have it. no gcode passwords in use.

I added a gcode password cia sd card direct and laptop would still not connect.

Big printer now running via sd card gcode transfer and orint from touchscreen.

Either there was an old netwrk security key i entered once (and no longer have) or the laptop is now demanding one and quite possibly not working proper as ad hoc/password, or not.

I appreciate duets do not need internet access. They don't have it either!

That's what I think, but something to figure out after the show. Glad to hear that you got the printer up and running again. Good luck!

FuseDeep

@infiniteloop Thanks.

My question is...does each duet board have a network security key, and where do I find it?

I think not honestly...

FuseDeep

@infiniteloop

And...putty is not connecting (yat won't install) so cannot simply check things.

Must get point6 machine working too...(as well as fusedeep).

Short answers: No, and nowhere. After the show, use the link @Stephen6309 posted: that's a good reading to understand networking with the Duet. The "network security key" the laptop asks for is something which originates from the software router (on your laptop), and as you see, its security is perfect: you are locked out

FuseDeep

@infiniteloop

My android phone is asking for a password now.

MODS/tech supremos, I really need to know how to get round either phantom network key request/password or a reset of the board and keep my machine set up!

Definitely no password on fusedeep but now always asked for key, not sure about point6 machine but do not have the password anway (and sd card well tucked away currently).

Must get both machines working properly ASAP.

Thanks Rich

Stephen6309

@fusedeep On the duet, do you have a SSID/password set up for the wifi connection and does that work?

FuseDeep

DEFINITELY no gcode passwords on either set up.

Just checked.

So, my laptop now seems to be looking for a "network security key" (different to password) and, oddly, my android phone won't connect to either without a password (so won't connect).

i did add a password to FuseDeep but it did not connect properly. Now removed (via SD card direct edit.

Plus putty not connecting and YAT borked ages ago.

Am in real trouble here!

Sorry, missed this one. Putty (or yat, or DWC, …) won't work because you've lost your local WiFi network - which, until now, was managed by your laptop (as a "software router"). Without this, your WiFi devices cannot communicate.

As I already told you, I see two options:

get your laptop to connect to the router (no idea how, sometimes you can find the initial password on the back of the router). Or you reset the router and re-configure it from scratch.

configure the Duet in WiFi access point mode (you got the proper link from @Stephen6309), then, try to connect from your laptop or your phone.

As I've learned, you don't have a physical router, so option #1 now means to re-establish the routing functionality of your laptop…

So, my laptop now seems to be looking for a "network security key" (different to password) and, oddly, my android phone won't connect to either without a password (so won't connect).

If you don't recall the "network security key", how shall I? Forget the passwords on the Duets, it's the (local) network that matters. Currently, you don't have any.

Be happy that you can control one of your printers locally. On the other one ("point6", I guess?), you can try option #2, but be warned: it takes some time to properly set up the Duet as a WiFi access point.

fcwilt

@fusedeep

Do you by any chance have a standalone WiFi access point?

With that you could setup the Duets as typical WiFi clients.

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.

FuseDeep

@fcwilt Nope, never ever have had.

Always worked fine til my laptop wifi borked.

FuseDeep

@phaedrux

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.

droftarts

@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.
