Greetings. Yesterday, I had a strange problem with my Xiaomi: Out of the blue, websites stopped loading. Facebook and Twitter apps stopped updating. It seemed like my Internet connection had a problem, but every other device worked properly. The Wireless icon was normal. The Network Details marked it as "Connected", with full signal strength. However, I had no Internet connection. After a few tries, an app named WiFix helped me solve the issue. However, today, the problem happened again, and this time, no app helped me. I even tried re-installing the ROM (WIUI-3.9.27) and it persists. Help, please? Phone: Xiaomi MI 2S. Bought 3 days ago.
