Wolves caretaker manager Terry Connor admitted the 3-2 defeat at Wigan had summed up the relegated side's campaign.
The Molineux side finished the season having conceded 82 goals and it was their leaky defence which saw them concede an early lead at the DW Stadium.
Even a late consolation to improve the scoreline could not gloss over their problems and new manager Stale Solbakken will have much to address over the summer.
Wigan capitalised on some weak defending as Emmerson Boyce, who has excelled on the right of midfield since manager Roberto Martinez adopted a 3-4-3 formation, scored twice and could easily have had a hat-trick.
Matt Jarvis had put Wolves ahead but Franco Di Santo and Boyce turned things around very quickly and when the latter spectacularly volleyed home in the second half the result was put beyond Wolves despite substitute Steven Fletcher's late consolation.
Connor, who will hand over control to Solbakken on Monday, said: "It was a frustrating way to sign off. It encapsulated the whole season and the reason why we have not been able to stay in the league. We had plenty of honest endeavour and commitment and no lack of attacking flair but we keep shooting ourselves in the foot by making mistakes as individuals."
