I use KIS on several home PCs and tablets on a home network. The PCs are 2x W10, 1x W7, all 2.4G wifi. KIS is fully up to date everywhere, W10 is 1903.
With one of the PCs, I am having problems making it discoverable on the network - it is set up to be so, but sometimes is and sometimes isn't. Also, file transfer from this PC is unreliable. As far as I can see, the wifi signal is good everywhere (internet connection is good and fast).
In investigating this, I have noticed that in KIS under protection >> firewall >> networks, not everything is now listed. It used to be that on each machine, two networks would be listed - an internet public connection, and a local connection. The former being the internet connection via the ISP, the latter being the local network.
Now, on the 2x W10 machines, only the public connection is listed by KIS.
I am not sure if this shows any light on my problem, but something has clearly changed. What is it that makes a network connection show up under firewall - or not?
