Once again I am building a headless Centos 7 box that needs to reliably be on both the LAN and WIFI network at all times. Amongst other things it's going to be an AirPrint bridge enabling IPads to print to printers on a different VLAN.
I have asked about this before and got a solution working using nmtui to set up both the LAN and WIFI interface, and activate them. However, the WIFI link is unreliable. Sometimes it doesn't activate, or after a while de-activates. Sometimes it doesn't even appear in nmtui to enable me to activate it.
Can anyone help me with how I can set up a more reliable server.
Thanks

The server I was using was an old workstation PC that I re-used for this purpose. I have now purchased brand new kit and done a clean install.
This box has now been running fine for a few days until this morning, when the WIFI dropped off again. To investigate this I have had a look in /var/log/messages and I have found lots of entries.
At the bottom is where I re-activated the interface. Above that there are lots of entries where it toggles between inactive and disabled. Above that at 09:33 there is an incident, and before that all looks normal.
I have posted the log here:

Can someone give me a clue how to fix this.
Also, it was suggested that I use nmcli in a cronjob to re-activate it if it drops. I can check to see if it's still active by 'grep'ing the IP address, but I don't know the nmcli to re-activate an existing WIFI connection.
Can anyone help here too, just in case I can't fix the real problem
