James Wesolowski and Dean Furman both scored their first goals of the season as Oldham comfortably defeated Wycombe.
The Latics dominated as Furman shot wide and Shefki Kuqi and Jean-Yves Mvoto were both denied by Nikki Bull.
Wesolowski gave Oldham a deserved lead, volleying in at the near post from six yards after Chris Taylor's cross.
Joel Grant fired over a rare chance for Wycombe, but Furman sealed the win when he collected Robbie Simpson's cut-back and shot home from 16 yards out.
VIEWS FROM THE DRESSING ROOM
Oldham Athletic manager Paul Dickov told BBC Radio Manchester:
"I said to the boys after the game, not in an arrogant way, listen to what we're telling you as football is a simple game.
"Two really good goals, and we're delighted as a group with the first goal as it's something we work on in training.
"Everything that's good about us, Dean's (Furman) is usually at the heart of it, and I thought he was excellent."
Wycombe manager Gary Waddock told BBC Three Counties Radio:
"You are judged on the result and we have come away with nothing, so we are disappointed.
"They (Oldham) got the goals and went on to win the game quite comfortably. We didn't work the keeper during the course of the game. It was a difficult afternoon for us.
"We tried to change it to put a spark into our play but it wasn't to be today. "
