Hi all,
I installed Slackware ARM on the Rpi4, and I have a conundrum:
The network connection doesn't start automatically even though the info is in /etc/NetworkManager/system-connections.
As a result, I can't obtain the time and DNS doesn't work.
When I log in as any user and start X, the connection starts but the network time isn't fetched.
So I have to log in as root, run ntpdate and get the time.
Then go back to X and use it.
Question: Is it expected that the Wifi won't automatically start during boot-up? I don't have Ethernet to connect to.

How is it configured though? Examine the config file and make sure it is configured to connect automatically. Specifically, make sure that 'autoconnect=false' is not present...

Also, as per this thread, make sure that "All users may connect to this network" is slected for this connection.

This is the new one that is almost working well. It seems to connect eventually, usually after I've logged in, but it never uses NTP to get the current time.
When the system boots up and I log in as root, if I type iwconfig wlan0 essid FunnyOne,
it will give an error saying connection is already in progress.

You could go for the standard Slackware "way" to do the WiFi connection by using its init scripts. Disable NetworkManager, stop it and remove the executable bit from /etc/rc.d/rc.networkmanager

Maybe I should, because even though NetworkManager is supposed to be executing scripts in its dispatch.d directory (according to posts here and the manual page), after much experimentation, I'm finding those are definitely not getting executed.

NetworkManager has been working fine for me on Rpi's 3 and 4.

You could try removing and re-adding the connection in nmtui command line interface:

$ nmtui

"Edit a connection" -> Select the wifi connection and <Delete>
Then <Back>
Then "Activate a connection"
Select the connection and <Activate>
Enter wifi password

Wow, thanks for that tip. It's mostly working now except for NTP.

Great for NTP suggest to disable any manual hacks in rc.local or otherwise, and just
$ chmod a+x /etc/rc.d/rc.ntpd; /etc/rc.d/rc.ntpd start
Should take care of any ntp issues.
