Google has done it’s usual job and returned lots of results but not led me to a solution.

I’ve just build a CentOS 7 “File and Print Server” config, i.e. no screen/keyboard/mouse and no GUI installed.

The LAN connection has worked out of the box and I can SSH into the server without issue.

However, I cannot find out how to configure the WIFI connection which I need in order to provide Air Print services.

I’m using a USB dongle which the kernel has recognised and provides me with a device. I can use that device to scan for available WIFI networks. What I
can’t do is configure a connection so that the server can connect to the the WIFI network.

Can anyone help with a link to suitable instructions?

Cheers

Gary
