The 29-year old midfielder came out of contract at Loftus Road at the end of last season and he still feels is good enough to play for a tier two side despite being sent on loan to League One champions Charlton Athletic last term.
"I have had offers from League One clubs," said Cook. "But I am just waiting for a Championship club to show some interest and make a move.
"At the moment that has not happened and I am surprised by that, but I have spoken to a number of other players who are in the same boat.
"I felt that going out on loan last season and being able to get those games under my belt I might have had an offer from somewhere.
"However if that does not happen then I will look to League One and focus on staying there for just a single season before earning the right to play in the Championship again."
