QPR duo Dexter Blackstock and Emmanuel Ledesma each scored to help their side to a comfortable win over Doncaster.
Blackstock opened the scoring when he tapped in from close range in the fifth minute after Daniel Parejo lifted a free-kick into the area.
Lee Cook fired wide and Damien Delaney shot over before Ledesma added a second after 28 minutes.
The Argentine latched on to a long punt forward, held off two challenges and tucked the ball past Neil Sullivan.
QPR boss Iain Dowie:
"The attitude, application and desire of the players to embrace what we are trying to do has been terrific.
"Doncaster are a very good side, one of the best passing sides in the division, and we nullified that and we had a creativity.
"The defeat at Sheffield United hurt and we spoke openly and brutally about that in the week and put it to bed. The response was a clean sheet today."
Doncaster manager Sean O'Driscoll:
"You have to give credit to QPR. They learned from that defeat at Sheffield United and were much more solid today, they made it difficult for us.
"Eight of their players are over 6ft 2ins so it's not rocket science to say you have to defend properly at set-plays, so we're disappointed with that.
"It's the first physical test we have faced in this division and we struggled to find a way to get a result."
