Ring base keeps getting disconnected from Wifi despite all good wifi good signal

I recently setup my ring with wifi which just on different room than my router.The wifi signal are in full bar.After couple hours, the base alarm said the wifi gets disconnected.And i tried to set it up again with different wifi.And the next day, it gets disconnected again from the wifi. Despite all my good wifi signal.After reconnect to the wifi again, i tried to reboot the base, after reboot, it gets disconnected to the wifi again.Is this a common issue?Am I getting a bad ring base product?Thanks
