I have bought a 2012 13' Macbook Pro Retina in Christmas Holiday. And actually I am a beginner on MAC. After bringing the Macbook home and finished all setting. I find that there are some problems on connecting the Wifi. 1. The icon on top right hand corner show me the Wifi signal is in the best state 2. When I only use Chrome to do searching on the internet. The Wifi is function well. 3. When I use Chrome and Skype at the same time. Wifi Disconnect will be happened. My skype will be disconnected per 20 mins. But the Wifi icon is also in the best state. 4. When I use Chrome, Skype and Sopcast at the same time. Then the Wifi is disconnect frequently. However, the icon also show me the signal is in the strongest state. 5. When I shut all the apps down and open Chrome again, it takes a long time to open a website (20 - 30s). I need to restart my Macbook, then everything get fixed. Hence I really want to know is my router (TP Link, 802.11g) not compatible/matched with my Macbook. Because my sister also have a 15-inch Macbook retina, she also have the same problems, the wifi connection is very very slow (sometimes). But my PCs, iPhone, samsung galaxy and iPad are work fine with my router. Do I need to buy Airport or Time Capsule to solve the problems. Million thanks for the advice.
