The Owls and Charlton shared the points at The Valley on Saturday.
Wednesday started brightly in South East London and took the lead through Royston Drenthe, who was a thorn in the side of the Addicks from the first whistle.
Charlton, though, hit back after the break to preserve their unbeaten home record.
Returning striker Igor Vetokele finished from close range to ensure a share of the spoils.
Handed his first start for the Owls, Drenthe was a livewire in the opening ten minutes.
The winger sent in two dangerous deliveries from the right; first a corner that Joe Mattock diverted just wide and a second that had a fraction too much pace for Atdhe Nuhiu.
There was little to trouble Keiren Westwood in the early throes, save a George Tucudean low shot and a Jordan Cousins header that flew over the bar.
Drenthe was in the mood at The Valley and the loanee almost registered the game’s first goal on 13 minutes after cutting inside and drilling just wide of the far post.
But there was simply no stopping the ex-Real Madrid man, who duly bagged his first Owls goal just before the half hour mark.
Drenthe turned sharply on the halfway line and motored upfield before neatly tucking home a powerful strike past Stephen Henderson.
Wednesday almost caught Charlton on the break in first half stoppage time, with Nuhiu leading the charge before feeding Chris Maguire who dragged wide.
The first clear cut chance of the second period fell the way of the visitors as Maguire’s teasing centre fizzed dangerously across the face of goal, just beyond Nuhiu in the middle.
As Charlton sought a way back in the game, the hosts began to turn the screw and put Wednesday on the back foot.
Chris Solly thumped inches over the bar after a sustained period of pressure and Westwood was at full stretch to tip over the bar from Tucudean’s volley.
The Addicks then found their leveller through returning striker Vetokele who was well placed in the middle to tap home from Rhoys Wiggins’ low centre.
Wednesday had claims for a penalty turned down by the referee when Nuhiu was challenged by Tal Ben Haim in the area.
At the other end, Vetokele was looking a threat for the Addicks and put wide following a breakaway and Lawrie Wilson saw his late strike ruled out for offside at the last as the sides shared the spoils.
