Edwards popped up eight minutes from time to settle the clash after Wycombe's Scott Rendell cancelled out Joe Jacobsen`s opener.
Wycombe enjoyed the best of the opening exchanges and Rendell had the ball in the back of the net after nine minutes - only to see it ruled out for a foul.
But after Scott Donnelly and Rendell both wasted further chances it was Stanley who grabbed a 43rd -minute lead when Jacobson poked in Charlie Barnett's corner.
Rendell made amends for his first-half wastefulness by notching Wycombe's equaliser on 52 minutes, firing home after Edwards failed to clear a cross from the right.
But with Wycombe pushing for a winner the visitors helped themselves to the three points when Edwards popped up with his eighth of the season on 82 minutes, heading home Barnett's left-wing free kick.
