My latest 15 inch MacBook Pro is unable to connect to a wifi network, probably because the router is pretty far away. However, my Samsung Note 3 is able to connect to the same wifi network. How is it possible that the latest laptop have worse wifi connectivity than a 3 year old phone? I've tried turning off my Note 3's wifi but it still didnt work so interference is not the cause. Is there a way for me to determine if this is due to a low quality wireless network card and get Apple to replace it?
