The West London outfit are yet to snatch a victory in the Premier League and a host of fans waited outside Loftus Road following QPR's 3-1 defeat to Southampton on Saturday and chanted "you're only here for the money".
"Everybody in the dressing room was hugely disappointed with the result," Hoilett told the club's official website. "We're all really disappointed and frustrated with how things are going at the moment, but we will work hard to put it right.
"I can understand the fans' frustrations. We're as frustrated as they are because we want to change this around and climb the table. We've got to stick together as a team."
QPR have taken just four points from 12 games.
