JORDAN RHODES and Theo Robinson struck to put Town back into the League I play-off zone.
But visiting fans had to endure a tense finale after Dean Keates pulled one back for Wycombe with a 73rd-minute header.
Rhodes showed great reactions to score his 21st goal of the season with a spectacular 22nd-minute overhead kick after Michael Collins' shot took a deflection and looped into the air.
And Robinson's 11th of the campaign, in the 52nd minute, was equally pleasing on the eye, with the striker belting home a shot after beating three men on a run along the edge of the penalty area.
The three points, coupled with Colchester United's defeat by Exeter City the night before, put Lee Clark's side back up to sixth with seven games remaining, the first of them at home to Oldham Athletic on Tuesday night.
The Wycombe game was watched by 5,288.
