Subject: Hash return is not correct

class Router
  attr_accessor :make, :model
  def initialize(make, model)
   @make = make
   @model = model
  end

  def ==(other)
    return false unless other.is_a?(Router)
     make == other.make && model == other.model
  end

end

frequency = Hash.new(0)
models = %w(2000 3000 2000 3200)
models.each{|m| frequency[Router.new('Linksys',m)] += 1}
puts frequency[Car.new('Linksys','2000')]



puts should be '2' but I am getting 'zero'
