DWC does not connect to any browser

3DinoPrint

Hardware: Duet2Wifi and Duex5
Firmware: 3.4.5

M122 (via serial tool) shows:
Wi-Fi
Network state is active
Wi-Fi module is connected to access point

When I type the address 192.168.178.xx shown in the router the browser replies „connection could not be established to the server“

This appeared after several hours of configuration work on my CoreXY printer using DWC.

Where does the error come from?

Check the SD card in your PC, are all the folders present?

You could try replacing the files in the WWW folder with a fresh set from here: https://github.com/Duet3D/RepRapFirmware/releases/download/3.4.5/DuetWebControl-SD.zip

Can you copy and paste the full result of M122?

3DinoPrint

@Phaedrux Thank you for your quick answer.
I changed the files of „www“ and restarted the printer. Unfortunately the error remains.

Here you find the results of M115 and M122:

@3DinoPrint said in DWC does not connect to any browser:

192.168.178

What IP address does your computer have? Are you even on the same subnet?

3DinoPrint

@Phaedrux 192.168.178.96
With this address the printer is connected to the router

Phaedrux

Yes, but what is the IP address of your computer?

Can you ping the printer IP address from your computer?

3DinoPrint

@3DinoPrint Actually I am working on an iPad, which is also shown as connected to the same router via Wi-Fi.

Attached you find a screenshot from safari, my browser on the iPad:

3DinoPrint

@Phaedrux the iPad is connected with 192.168.178.93

3DinoPrint

@Phaedrux I managed to ping the address from my computer:

Does your router have wireless client isolation perhaps? It would prevent wireless clients from reaching each other.

And does it load DWC in the browser?

3DinoPrint

@Phaedrux I just tried to connect via ethernet from my PC. With all three devices and different browsers it is not possible to connect.

Phaedrux

Please test the Duet in Access Point Mode.
See here for details on how: https://docs.duet3d.com/User_manual/Reference/Gcodes#m589-configure-access-point-parameters

This will have the Duet create its own WIFI SSID that you will be able to connect to using your devices wifi menu. The duet becomes it's own router. Then you can try reaching it from a browser.

Does that make sense?

3DinoPrint

@Phaedrux I successfully set up an access point and DWC appeared. I think I will write two macros to change between a connection to Wi-Fi from a router and to an access point. Thank you for your support.
