Ho Ho I did this with one of my bikes... it's pretty old. The drive chain is as quiet as a mouse until I put any power on it then the cassette slips ... The sprockets on the cassette are worn out. Slightly irritated as the plan was to sell the bike without having to update anything. So if you have an old bike... don't clean the chain so well. LOL. Terrible thing to say.
Did you put on at least 20 miles on the freshly waxed chain? If not put some easy miles on it to work the wax into the tight spots. After 20-30 miles there is no reason the wax wold cause your chain and cassette to skip any more than with chain lube.
