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

FuseDeep

@infiniteloop I use adhoc wifi to duets but the laptop seems to be trying to get the key for a central router.'

There isn't one!

Stephen6309

@fusedeep Can you go to a web page, like www.google.com? Are you sure the laptop is logged in to the WiFi?

FuseDeep

@stephen6309 positive. am using my phone hotspot now to respond and internet works. but for adhoc to duets it wants a network key. there isn't one...

What is duet netwrok security key?

Normally: none. @Visionary told you how to set/change the PW in config.g on your SD card. He's right - I just advise you to put the following lines into your config (if they are missing):

M551 P"reprap"
M552 S1						; Turn network on

Setting the password (with M551) to "reprap" tells the Duet not to ask for a password at all.

If you've done this, you can be sure that any requests for a password originate from another source - router or laptop.

@stephen6309 I don't think it is this.

It was all fine, for months until my laptop wifi crashed out.

Now it is asking for a network key for my duets. they don't afaik have one!

It is a genuine pita.

FuseDeep

@infiniteloop I did exactly this and it made no difference. I put a new PASSWORD via and sd card reader and notepad edit and it would not connect.

The laptop is asking for a SECURITY NETWORK KEY

This is incorrect,

This is a laptop /adhoc issue and not duet as such.

Though my android phone won;t connect either, but i also never tried that before.

Well, that's not the Duet. I think your laptop messed some things up…

Remember: Don't panic! IMHO, you have 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.

BTW: do you happen to have a PanelDue attached to at least one of your printers?

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…

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.

@fusedeep

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

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