Q: MacMini won't auto connect to preferred WiFi Network when Router restarts
My MacMini is set to join my preferred wifi network. Where I stay, there is usually a power cut of around a minute or two during day.
My setup is such that my MacMini runs 24x7 with a backup UPS but my router (AirPort Express) turns off during that power cut. When the router turns off, my Mac gets disconnected from the network which is expected but now when my router turns back on, the MacMini won't reconnect to the preferred network.
It shows the preferred network in the list and when I manually click on it, it instantly reconnects without asking password. But this doesn't happen automatically.
If I restart my MacMini it reconnects fine. The issue is only happening when my MacMini is on but my router restarts.
To reproduce this issue at your end, simply turn off your router and once your Mac disconnects from the network turn the router back on. See if your mac reconnects to your wifi fine.
Any solution or advice for this issue?
Thanks.
Mac mini, OS X El Capitan (10.11.3), AirPort Express (2nd Generation)

So I think my assumption was correct. It was the Wifi initiation issue which was causing it not to connect.
Finally able to resolve the issue by using the solution created by tjluoma:

Only change I did is to set the script to fire at regular intervals.
This is something ideally Apple should support by default. But for now I'm good with this solution.
