Two goals within two minutes took the wind out of the Yachtsmen's sails.
Leading scorer Jason Hallett had to pass a pre-match fitness test, but quickly went to work, his first-half double setting the visitors on the way, with Liam Hope adding a third after the interval.
The Yachtsmen remain a point outside the relegation zone with two games to play.
The match was preceded by a minute's silence in memory of former Wroxham committee member Ronnie Hudson.
Cheshunt attacked from the off, although visiting keeper James May had to be on his toes as midfielder Jack Garrod whipped in a couple of teasing crosses.
Hallett then went close twice within the space of five minutes, but with just over the half-hour played, he struck – his first shot was well saved by Elliot Pride but the ball rebounded off the Cheshunt forward and bounced into the net.
A minute later it was 2-0, Pride again saving well, down to his left, only for the loose ball to reach Hallett, who reacted quickest on the edge of the area and placed the ball into the bottom corner.
There was controversy just before the interval which continued as the players and referee left the pitch. A Cheshunt player went down in the Wroxham area and referee James Turner waived away the protests from the visitors' bench. Cheshunt players and management harangued the referee and his assistants as they left the pitch, with visiting manager Paul Wickenden dismissed.
