Think of putting repeater closer or watch out for any extra power devices that can cause interference if the error persists. To examine your extension’s firmware differently , please use another way rather than the one above specified. Check for any firmware upgrades on the dashboard page of the web interface for your extender. You may download and install a current firmware version if there is one accessible.
