In my house my router is downstairs and upstairs in my bedroom I have my macbook and PS3. My macbook receives a strong four bar signal strength yet my PS3 receives under 20% strength which is really slow and often loses connection. I've been trying to share the wireless connection from my macbook to my PS3 using an ethernet cable but I have had no luck so far. I've watched various tutorials on youtube to do this with the xbox (since not all of them have built in wifi like most PS3s do) and I've tried to follow the same setup with my PS3 but nothing has worked. If anyone could show me how to do it, or give any suggestions that would be much appreciated. Thanks.
