Harry Redknapp's side are currently bottom of the Premier League after a run of 16 games without a win, and they were unable to hold on to the lead in Saturday's 2-2 draw at Wigan.
Redknapp is likely to want to bring in a number of new faces in January but Hill believes that too many new signings could have an adverse effect on the team.
"The chairman is throwing money everywhere - left, right and centre - and sometimes that doesn't work. You've got to stick with people and work on them and try and get the best out of the ability they have," said Hill.
"Don't get me wrong, I do think we will try to get a couple of players, but I don't think it will be five, six or seven like people are talking about.
"It might just be the players to help us along and hopefully that will be it. I've been here three years now and I've seen loads of players come and go. I just think we need a bit of stability at the moment, a settled team and a system of play that suits us. I think we're getting there."
The defender was also honest in his assessment of QPR's season so far, saying: "The table doesn't lie, we've been poor. But we've got some good players here and we just need confidence to go out there and perform and win games.
"The longer it goes on, the bigger the next game comes and to be fair, they don't get much bigger for us than a derby against Fulham on Saturday.
"If you can't get up for that game - no matter what position you are in the league - there's something wrong with you."
