Hello. I've been trying to setup a working hotspot for quite some time now. Internet is provided to the laptop via USB-A ethernet adapter, laptop has Realtek wifi interface that supports AP mode and other modes. Running on KDE Neon (with Plasma) latest version. WIFI Hotspot worked flawlessly on Windows 10.

I would like to post logs of what happens when i try to connect from Android phone / other devices, but don't know how to log (complete newbie). I tried to run the lnxrouter command in various ways, but can't manage to get any device connected, Android phone shows that it is stuck on "obtaining ip address".

try: 1) 'firewall-cmd --zone=trusted --add-interface=<SUBN_IFACE>' 2) disable firewalld

try: 1) 'firewall-cmd --zone=trusted --add-interface=<SUBN_IFACE>' 2) disable firewalld

It seems like I don't have firewalld installed, since it says:

Command 'firewall-cmd' not found, but can be installed with:
sudo apt install firewalld

Googling I found this post https://www.reddit.com/r/kde/comments/lgzfyj/is_there_going_to_be_a_firewall_integration_with/

I don't have any knowledge about the KDE neon distro. I saw some terms like ufw, plasma-firewall ... in that post.

Check if there's any firewall related services running. Disable them and try again.

You should figure out to provide log and more info so people have the change to find the reason.

And use systemctl |grep service to see what services it has.
