Ether can only form one hydrogen bond per molecule.
We know that the hydrogen bond is the kind of bond that occurs when the dipole of water interacts with the dipole that is on another molecule. We can see this in a lot of hydrides of electronegative elements.
We can see that ether has only one electronegative atom and that is oxygen from the image that is shown in the answer. This oxygen atom can interact with the positive end of the dipole in only one water molecule at a time.
