@Chun-Wai-Yuan it could be several different issues which keep the omega2 from connecting. there are many posts in the forum already that discuss methods to correct this problem. if you enter "can not connect to wifi" or "unable to connect to wifi" in the search box in the upper right you will find some probable solutions others have found to work.
@Zheng-Han I'm curious, is this actually hard-coded in the driver, or are you just talking about your WiFi-configuration tools not being to do this? If it's actually hard-coded in the driver..... :confounded:
