Rangers played out a 2-2 draw with the Welsh outfit at Loftus Road in the Championship, despite going 2-0 up at one stage.
The home team took the lead against the run of play in the 33rd minute when Clint Hill headed in a Matt Phillips corner.
Charlie Austin doubled QPR’s advantage 11 minutes into the second half when he turned the ball in from close range.
Sean Morrison halved the deficit with a stooping header on 63 minutes, and Scott Malone fired home from 22 yards late on to salvage a point for visiting Cardiff.
It was QPR’s first point of their 2015-16 Championship campaign, and Fernandes was pleased with the players’ effort.
The Rangers chairman also highlighted on Twitter that the team is a work in progress, but former QPR forward Rodney Marsh pointed out to Fernandes that this has been going on for four years.
