Make sure that either your player or the objects have a rigidbody2d (in your case), and some form of collider2d - if you are using a polygon collider, make sure its optimized, otherwise it might be passable, and if you are using a line collider, make sure the lines are facing the right way, otherwise it might be inside-out and also passable to enter, but not to exit

trying to move the player in your collision function wont work cause it only triggers once. the movement needs to happen in Update bbecause it repeats every frame, anyways, simply multiplying your speed by -1 will change direction for you. i would also check to make sure you have your colliders set up properly try changing this part like this:

if(other.transform.name=="collider1"){ print("my collider is working...yay"); speed=speed *-1;}
