Yeelight Ceiling light Moon Connection issues

Hi! I recently had to change my router to a Asus Zenwifi bt10 and i have trouble connecting to my yeelight ceiling light moon, but the other yeelight bulbs are fine.I am on singapore server.

im on wpa2-personal, 2.4ghz but i still cant connect, everytime it hits 100% it askes me to retry.
I can add the yeelight ceiling light moon , if i connect to another mobile phone’s hotspot, but when i switch back to my router’s wifi it will grey out and be offline.

Please advise.
