[Question] How to use Tasker to connect to specific WiFi

Hi Guys,
I have the following problem and tried to solve it for the past few days, but I cant do it, so I hope that you can help me with it.

I have two WiFis with the same name, one on 2,4GHz and one on 5GHz.
It seems that Netflix cant see my chromecast ( 1. Gen - so only 2,4 GHz wifi) if I am connected to the 5GHz.
Now my question is can I use tasker to connect to the 2,4GHz if I launch Netflix?
I think the best way is to connect to a specific Mac address, but I cant figure out how...

Thanks for your help
