How to force connection to a specific SSID?

[Chris Green]

I move around quite a lot with my laptop, to different places in the
house, to other houses and to my boat in France.  Thus there are a lot
of WiFi SSIDs configured.

Sometimes I want to force it to connect to a specific SSID even when
there are other stronger ones around.  For example, recently, I was
testing configuring a Raspberry Pi as a WiFi AP and I wanted my laptop
to (try to) connect to that AP even though there were other stronger
ones around.  Similarly when I'm on the boat in France there are often
several WiFi signals from different providers and I want to connect to
a specific one where I have an account.

I know that I can select the SSID in the "Network" app in the panel
but this only stays selected for one attempt, if it fails then I'll
get connected to another SSID that I don't want.

Is there a way to tell Network Manager that I want to keep trying the
same SSID even though there are other 'better' (but not for me at the
moment) SSIDs around?
