Hi, I got a rMBP 13'' a couple weeks ago and I noticed a problem, I don't know if it's rMBP or Wi-Fi router. Sometimes web pages simply stop loading and stuck in something like 10% (like in the picture) and internet stops working. Wi-Fi appears completely working on my Mac but it really doesn't. Turning of Wi-Fi and waiting a couple seconds and turning on Wi-Fi or sometimes just waiting solves the problem (not always). When this happens, Safari, App Store, iTunes Store etc. won't work. How can I fix it? Thank you and sorry for my bad english.
