I have a laptop running PCLOS KDE fully updated. It is configured
to connect to my WIFI network at boot with a static IP address.
Occasionally, I'll take the laptop to a public WIFI hotspot
and use the network center to find their SSID and connect
to the public network. I turn the laptop off (correctly,
using the Lock/Logout widgit).
When I get home, and I turn the laptop on, I do get connected
automatically to my WIFI network at home, but with a DHCP-ed
IP address (which is different than the desired static IP address).
If I bring up the network center, disconnect the connection,
connect again, I'll get back my correct static IP address.
I don't change anything in the network configuration: I just disconnect
and connect. Subsequent reboots at home always connect me
correctly with my configured static IP address.
What's going on?
