So, I don't know if my problem is unique, but I need an answer to it. My PS3 Slim is not connecting to any of my DualShock 3 controllers wirelessly. And, no, they are not out of battery. I can use them fine on my brother's PS3 Super Slim, and they have full battery there.
I feel like my problem is being caused by my PS3 Slim itself. If anyone can help, please let me know!
