How to get values from network settings panel?

Have you seen these?

get_blog_option()
update_blog_option()
delete_blog_option()

I’m on a mobile now so I can’t re-check this, but my guess is that the option value gets stored in your ‘master’ blog table and you’re trying to access it from a different blog/site. Could that be the case?

Try passing the master blog ID to the functions listed above. Something like:

$options = get_blog_option( 1, 'ad_options' );

Just a guess though .)
