connectivity of the group of orientation-preserving homeomorphisms of the sphere

In the paper "Local Contractions and a Theorem of Poincare" Sternberg has mentioned the following question which was open when the paper was written:

Is the group of orientation-preserving homeomorphisms of the $n$-sphere arc-wise connected?

According to Sternberg's paper Kneser has shown this to be true for $n=2$. Does anyone know the current status of the problem?
