Network: Should use WIFI or network cables? Which is more secure?

If you live in a high-rise then it’s better to use an inexpensive network switch and connect each computer with a CAT 6 network cable. This will also give you better transfer speeds.

Network: Can I turn IPv6 off and use IPv4 only?

Yes, that will work fine. Down the road, IPv6 will become necessary but we are not there yet. And as they say “less is more”. There is no harm in leaving it turned on and Gnome has a setting to use it for local network traffic only via Settings > Network > cogwheel > IPv6 tab > check mark at the bottom of the window.

Network: How do I turn off internet access while keeping a computer on the LAN?

Go to Settings > Network and click the small cog wheel. A new window will pop up. Select IPv4 and check the bottom option “Use this connection only for resources on its network“.
Click on the blue APPLY button to close the window and then toggle the switch beside the cog wheel off and on to restart the network.

Network: Wake up on LAN is not working. Is there another way?

Go to Settings > Power and turn off Automatic Suspend.
This way, your computer won’t enter suspend mode although the monitor will turn off while the system accepts SSH access.

Network: I can access computers on local network but can’t go online

Go to Settings > Network and click the little cog wheel. From the popup window, select the IPv4 tab and uncheck the “Use this connection only for resources on its network” option at the bottom of the window. Click the blue APPLY button and lastly restart the network by turning the switch next to the small cog wheel off and then on again.
