This past Tuesday, I purchased a brand new Macbook Pro from the Apple Store. It is the 13-inch without Retina Display (see specs here: https://www.apple.com/macbook-pro/specs/). At home, my room is in the basement, and our Wifi router is in the office one floor up on the opposite side of the house. When I try to use the laptop in there, the Internet seems to cut in and out. It will say I am connected to the wifi network, but webpages won't load in Safari. Sometimes it will say that our wifi network isn't connected to the internet, but my iPhone and other laptops in our house are still connected to the internet just fine. When I use the laptop anywhere else in the house, it works fine. I never had this problem with my old Macbook from 2009. Another problem, when I was at college on Wednesday, I could not connect to the internet at all. I connected to both of my school's wifi networks, but I couldn't load any webpages. Again, I never had this problem with my 2009 Macbook. I took the laptop to the Apple Store, where they exchanged it for a new one. I am still having the same problem at home. I have not yet tried it out on my college's wifi networks or any other public wifi networks. Anyone have a similar problem or know what's up with this?
