Wednesday are taking some stopping in the race for promotion and flexed their muscle against Charlton to post a seventh win from nine games.
First half goals from George Byers and Callum Paterson told only half the story as the Owls were dominant from start to finish.
For the Addicks, the 2-0 defeat represented a fifth successive loss and Wednesday were in no mood to ease those woes.
After a flurry of corners from the first whistle amid a blistering start, they hit the front on five minutes.
Barry Bannan delivered an inviting set piece into the box and Byers cleverly glanced past the rooted Craig MacGillivray in front of the Kop.
It was that end of the field where play unfolded as the Owls bossed possession, with Charlton pushed on to the back foot.
The visitors had the occasional foray into the final third – Albie Morgan flashed a dangerous ball across the heart of the six-yard box – but Wednesday had overwhelming control.
Bannan was a whisker away from doubling the lead on the half-hour mark, sending George Dobson one way and then the other before curling inches past the post.
Marvin Johnson let loose with a long ranger that got the merest of deflections wide before the inevitable second strike came on the stroke of half time.
And it was a wonderfully crafted goal too – Massimo Luongo split the Addicks’ rearguard and slipped in Johnson, whose measured feed was converted by the onrushing Paterson.
The pattern was the same in the second half. Wednesday poured forward time and again, to which Charlton had no answer.
And the Londoners almost found themselves 3-0 down but for some desperate last-ditch defending at the back post from Chris Gunter to deny Johnson.
In truth, the remainder of the contest was academic. A third goal would hardly have flattered the Owls, who had to settle for 2-0 from a comfortable afternoon’s work capped with a return to the League One top six.
Wednesday: Peacock-Farrell, Hunt (Gibson 78), Storey, Hutchinson, Palmer, Johnson (Brennan 84), Luongo, Bannan (Sow 90), Byers, Paterson, Berahino (Kamberi 70)
