Advice from the article in the event you are using on of these devices:
Owners of DAP-X1860 extenders are recommended to limit manual network scans, treat sudden disconnections suspiciously, and turn off the extender when not actively used.
Also, consider placing IoT devices and range extenders on a separate network isolated from sensitive devices holding personal or work data.
