Definitely does NOT work

[jasmines]

I've a multisite wp. On a certain site, I've created a static page (let's say page id 179) where I want to show posts from all network. I've set this page as the blog page in WP dashboard.

Now, I tried all the techniques here: https://presscustomizr.com/snippet/three-techniques-to-alter-the-query-in-wordpress/

with no luck.

The simplest (that doesn't work):

add_action( 'template_redirect', 'hooks_setup' , 20 );
function hooks_setup() {
    if (  is_page(179) )
        {
          add_action( '__before_loop'     , 'set_my_query' );
          add_action( '__after_loop'      , 'set_my_query', 100 );
  }
  else return;
}

function set_my_query() {
    global $wp_query, $wp_the_query;

    switch ( current_filter() ) {
    	case '__before_loop':
		    $wp_query = new WP_Query( array(
        'network' => true
		    ) );
    	break;

    	default:
    		$wp_query = $wp_the_query;
    	break;
    }
}
