I am a new Mac user with a new Mac book pro. The Mac was connecting to wifi until today. Today I added another wifi connection through mifi hauwaei modem. Since then I cannot connect to my old wifi access point. It connects but not getting the Internet or get to the router using 192.168.2.1. I can still connect to my mifi. My iPhone, iPad and other laptops can connect to my old access point with out any issues. I use zyxel router as my old access point. If anybody have experienced similar issues? Or any solutions please help.
