Steven Craig grabbed his first goal in English football as Wycombe beat Southend United to earn their first win since the opening day of the season.
Dean Morgan headed the hosts into an early lead, meeting Sam Wood's free-kick for his third goal in two games.
The Blues levelled when Freddy Eastwood fired in his fourth goal in four games, following Ryan Leonard's pull-back.
But Craig glanced in Max Kretzschmar's corner to make it 2-1 and Wycombe held on despite several close calls.
