Problem with net learning XOR

I made a thread before about my neural net learning XOR. I was told, as the net was just a single perceptron, it wouldnt be able to learn XOR. I made it learn AND instead, that worked better. Now, Ive extended the net so it has a hidden layer with two perceptrons. Likts this: >- i1 -- h1 -- >< -- o1 --> >- i2 -- h2 -- i input, h hidden, o output. This net can learn AND, but not XOR... is it the limits of the net itself thats the problem again? Do I need a bigger hidden layer? Since it can learn AND I think the code must be all right... but I will post it if anyone wants to look at it. Just want to know if [n]in theory that net could learn XOR.
