STANLEY'S No 2 Jimmy Bell has warned his players that they face a relegation fight if they don't halt their five game winless run.
The Reds have picked up just one point out of the last 18 and have dropped down to 17th place in the League Two table after, earlier in the season, hoping they could challenge for a play-off spot.
They now travel to fellow out-of-form side Chester on Saturday with a win a priority.
"We have got an absolutely gigantic game against Chester," said Bell. "They are slipping down the league like ourselves and it is going to be a massive game and we have emphasised that to the players.
"We can't afford many more performances like Saturday."
The game against Wycombe was bleak with the Reds not having a shot on target until the 74th minute.
Stanley fielded one newcomer in defender Aswad Thomas, on loan from Charlton, and he made some important clearances but could not stop the Reds slipping to their four successive loss.
Accrington have conceded early goals in their last four games and did the same again when Wanderers top scorer Scott McGleish fired home in the 13th minute.
The hitman then had a penalty saved by Ian Dunbavin in the 34th minute but the promotion-chasing Chairboys made it safe in the second half following a defensive mix-up between Dunbavin and Graham Branch which allowed Leon Knight the easiest of goals.
"It was not the performance that was required," added Bell. "We did not have any spark."
