I believe the answer is:

betterment

I'm a little stuck... Click here to teach me more about this clue!

'wager period on network will' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe there's a link between them I don't understand?

'improved results' is the wordplay.
'improved' becomes 'better' (similar in meaning).
'results' becomes 'ment' (I can't explain this - if you can you should give a lot more credence to this answer).
'better'+'ment'='BETTERMENT'

'produce' is the link.

Can you help me to learn more?

(Other definitions for betterment that I've seen before include "improved condition" , "Amelioration" , "advance" , "Reform" , "Improvement" .)

I've seen this clue in the Sydney Morning Herald.
