Unable to attach after network wireless IP change

@Phaedrux when I try to use M588 or M587 I get a message that it failed - no available networks (even though there are many.

Phaedrux

What exactly did you send?

Here's what I sent and rceived.

Am I wrong that that the blue light on over the ESP unit flashes when it is trying to connect? That does not flash.

Phaedrux

Can you send M122 and check what wifi firmware version is installed?

If your SSID and password use special characters or capitals and your USB terminal doesn't always respect them, you can create a macro file that has the M587 command in it, save that to the macros folder as addwifi, and then use M98 P"addwifi" to execute it.

Also the Duet will only work with 2.4ghz networks, so if your new router is 5ghz only or uses a combined network name for 2.4 and 5ghz you may need to change that to provide a separate network name for 2.4ghz only.

Yes, I get the following....

The only special charactor in the pw or ssid is the "@" Other than that it's just a mix of upper and lower case letters and numbers.

Also the Duet will only work with 2.4ghz networks, so if your new router is 5ghz only or uses a combined network name for 2.4 and 5ghz you may need to change that to provide a separate network name for 2.4ghz only.

I turned off the 5gh network when I installed the new router so everything runs through 2.4gh. The router does not seem to see the Duet and I can not ping it. The blue network light is still out. Something seems to be turned off or not working.

Can you think of anything else to try???

Might the problem be that tellnet and FTP are disabled? Should both be enabled? Where would I set that.

thats not the output of m122

Can you send M997 S1 to try and re-flash the wifi module with the bin file currently on the sd card?

When sending M588 S"*" remember to include the double quotes around the asterix.

Now send these commands and let us know what it responds with.

Now to connect it to your wifi network you need to send the M587 command.

Sadly, I am beginning to believe the board is dead.

Did you really have ^ ? It should be *

Sadly, I am beginning to believe the board is dead.

There's nothing to indicate this. I think the problem is you just need to add your SSID name and password.

crchisholm

@Phaedrux Darn. To much going on. Yes. I did enter the ^ instead of the *. I guess my printer isn’t the only one with issues. I am away from my home computer so I will rerun these tomorrow.

Phaedrux

You can create a macro like this and place it in the /macros folder. Add your network name and password. Save it as addwifi

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

Then from the USB terminal send M98 P"addwifi"

crchisholm

@Phaedrux First off, I am not sure how to save this as a macro when I can't even get into the device.

I reran the three commands being more careful to avoid typos.....

You would need to put the SD card in your computer and use a text editor like notepad to create the macro file.

Or just download this file

addwifi.g

Open it in a text editor and add your SSID and password and put it on the SD card.

Then from the USB terminal send M98 P"addwifi.g"

crchisholm

Ok, I have done that. I copied the file to the MACROS folder on the SD and confirmed that it was readable and contained the correct info. I used your name "addWifi.g".

So now I am unsure where to go. How can I run that macro if I can't connect to the Duet????
