    Unable to connect whilst logged out, and other problems

    Hello.

    I have a three-device setup; a Kubuntu 20.04 laptop, a Windows 10 laptop, and a Raspberry Pi. These are all connected by wireless to the home router, and through that to the internet. All of these are able to ping each other.

    It is my understanding that - and please correct me if I am wrong - if I wish to use the Windows Remote Desktop to view my Kubuntu from my Windows, Kubuntu has to be logged out. But when logged out, Kubuntu does not connect to the Wifi. If the above is true, how do I configure Kubuntu such that it retains its wifi connection whilst logged out? After all, I know that my Windows connects to the internet on boot, not on login, and I want to replicate that on the Kubuntu.

    That is the first problem.

    I am also conducting some experimentation, and part of that involves putting an Ethernet connection between the Kubuntu and the Pi. I have configured it such that the Wired and Wireless interfaces on Kubuntu have different IPs, and that Wireless has higher priority than Wired, but they are within the same subnet still.
    (Specifically, it's because I need a secondary connection between the Kubuntu and the Pi that uses different interfaces to the general Wifi traffic; this was the easiest workaround).

    When that connection is active, the Pi is still able to ping the home router, the Windows, and the internet. But, whilst the Kubuntu is able to ping the Pi and the Internet, and it appears on the router and the Kubuntu itself as connected to Wifi, it is not able to ping either the Windows or the router despite being visibly connected to both of them still. Why is this occuring, and how do I ensure that the Kubuntu is able to retain connectivity to the other devices when in this setup?

    That is the second problem.

    I require aid with both of these problems; assistance in solving or otherwise working around this problems, in a way that does not involving installing further software on the Windows device, will be greatly appreciated.

    For the first, just go to System Settings' network connections section, and for your connection(s) go to the General Configuration tab, and check the "all user may connect' option. This allows the network connection to be up and available before a user has logged in.
