      Hello!

      My Duet3 6HC with Raspberry Pi 4B seems to work fine with a monitor, keyboard, and mouse, but I cannot seem to connect to it over WiFi.

      Since I am using the full DuetPi image with the GUI, I can set up WiFi through the GUI with the Raspberry Pi, and it seems to work: I can connect to my WiFi and search on the internet. However, when I try to connect from another computer on the network, the webpage at http://duet3.local/ is blank white.

      Here's some trouble-shooting steps that I have taken:

      1. Quadruple checking the wpa_supplicant.conf file as directed here: https://duet3d.dozuki.com/Wiki/SBC_Setup_for_Duet_3
      2. Configuring the wpa_supplicant.conf file from the Raspberry Pi itself, via following this guide: https://www.raspberrypi.org/documentation/configuration/wireless/wireless-cli.md
      3. Trying a different network - my mobile hotspot
      4. Trying to connect directly to the IP address of the Raspberry Pi (I tried this both on the WiFi and the hotspot)

      No matter what I do, it seems that the WiFi works just fine on the Raspberry Pi itself, but other computers on the network will return a blank page.

      I appreciate any suggestions! Thank you.

        Are you able to ping the IP address of the Pi?
        Does your router segregate wired and wireless clients?

          @phaedrux Thanks for your reply. I am able to ping the proper IP address:

          To answer your second question, I am not sure, but the Raspberry Pi and the laptop this ping was performed on are both on WiFi, and when I try to ping with my desktop (wired to ethernet), it is also successful.

          I think there may be a problem with DWC, since the network seems to work fine.

            But DWC works correctly on the local pi browser?

              @phaedrux Yes, it does. That is why I am so confused: everything seems to be working fine, so I am out of troubleshooting steps that I can think of!

                @danyzillla does typing the IP address in your browser work?

                  @nriviera Unfortunately it doesn't - I tried this method both on my hotspot and home WiFi, and both times I only saw a blank page.

                      @danyzillla Some routers and/or access points let you configure a security option to inhibit network traffic between connected devices. If the Pi is able to access the internet, that may be it.

                          UPDATE: Duet Web Control appears to work 100% fine on FireFox. For some reason, Google Chrome was blocking DWC. I realized this when I attempted to log into my router, and got a blank page as well - the problem was not isolated to DWC, but rather to my browser. Thanks to @chrishamm for suggesting I check my router!
