Hi  @Ruban3015,

If you are experiencing intermittent wireless connection on the range extender, please refer to the following suggestions:

1. Confirm the extender is properly located based on How to place your wireless Range Extender for optimal reception and performance.
2. Make sure the firmware on the extender is up-to-date.
3. Disable Parental Control or Access Control (Blacklist/ Whitelist) on the host router if they have been enabled for the extender.
4. Turn off Band Steering (also called "Smart Connect" or "Whole-Home Wi-Fi") and set up different Wireless names for the router's 2.4Ghz and 5Ghz Wi-Fi.
5. Fix the wireless channels on the host router, such as channel 11 for 2.4GHz and channel 48 for 5GHz.

For more details, please refer to What if the Range Extender keeps losing connection?
