Dominic Iorfa's first-half header was Sheffield Wednesday's first goal of the season
Nicolas Madsen's second-half penalty earned QPR a draw and denied troubled Sheffield Wednesday back-to-back Championship wins.
Domicic Iorfa's close-range header was enough to give the troubled Owls a deserved half-time lead from a beautifully flighted Barry Bannan free-kick.
But Bailey Cadamarteri's handball from a Richard Kone header gave Madsen the chance to level from the spot and the Danish midfielder slotted home.
Much-improved Rangers, seeking a fourth consecutive league win, played a full part in an increasingly open game full of chances at both ends, but neither side were able to snatch all three points.
Only the diabolical form of bitter rivals Sheffield United, who beat Oxford for their first points of the season, has kept the beleaguered Owls off the foot of the table.
But against a backdrop of continued and constant protests against owner Dejphon Chansiri's - and a third separate transfer embargo - the Owls managed to impress as they looked to back up the victory over Portsmouth last time out.
Wednesday keeper Ethan Horvath did have to make a couple of early saves before the hosts took control.
And it was no surprise that ever reliable captain Bannan, a rare and welcome constant during tumultuous times, proved the creator for the opener when his set-piece was turned in by Iorfa for the club's first home goal of the season.
At the other end, counterpart Paul Nardi did well to deny Liam Palmer and Cadamarteri then headed over.
But the second period saw Rangers up the tempo.
Karamoko Dembele - one of three half-time substitutes - hammered a shot just wide shortly before Madsen converted his penalty.
Wednesday responded, Palmer shooting wide from a clever Bannan pass and Cadamarteri heading over from another cross from Bannan, while Richard Kone smashed an effort over the bar for Rangers.
Neither side could take one of the many opportunities on offer, meaning the Owls have not won at home since the 2-1 success over Middlesbrough on 23 April.
Sheffield Wednesday head coach Henrik Pedersen told BBC Radio Sheffield:
"It was a generally strong performance. It has been very difficult at home but we played with strong discipline and showed strong belief.
"Defensively we were very solid, with good discipline, and we showed the next step on the ball and created chances.
"The second half we had a difficult 10 minutes at the start but we worked back. Altogether, it was a strong home game.
"We have showed we can compete with teams. The boys showed a big, big mentality. But we cannot have 14 shots and create five big chances and have only one goal."
Pedersen: 'I think it was a general strong performance'
QPR head coach Juilien Stephan told BBC Radio London:
"We were completely different in the second half. It was too poor for us in the first half.
"We had a good chance after two or three minutes but after that we didn't create anything and it wasn't good enough in terms of intensity and we were not powerful enough.
"We decided to change some things and to fix some problems at half-time and we had more quality and intensity. We scored very quickly and had some good chances.
"I enjoyed the fact that in the second half we were able to fight in the last 15 minutes. Is it a good point? I don't know. If we win against Oxford it is a good point. But credit to the opponents; they played well."
