I have a Raspberry Pi 3 (Model B). I want to use it as a terminal to operate a CNC machine as it has a Web Interface (Duet WiFi). I just need something with a browser and internet connection.
I first installed Raspbian and later on Ubuntu Mate, and both OSes show the same problem. They connect the first time and I can browse a little bit. From the second time on, the Raspberry Pi can see the WiFi and connect to it, but it does not load anything. Not even the CNC machine connected to the same WiFi router.
I have absolutely no experience with Raspberry Pis other than following Installation Instructions made for Dummies. So I don‘t know how to address it. Obviously I googled it, but none of the solutions helped me. I'm using a 3A power supply to be sure it has the juice it needs.
The Raspberry Pi is located literally 4 meters away from the router. I have another Raspberry Pi connected to that router and running Octoprint and it's never failed me, so I am assuming the router is not at fault here.
Any help would be appreciated. Thanks in advance.
