My 3 Deco X10s operating in router mode has really unstable wifi performance. Speeds are fine but devices will consistently get packet loss like on my Galaxy Tab S6 lite and Realme 5 pro. I am using the Wifiman app to show this happen in realtime on my phone. I am extremely disappointed in the performance of this router and I am past the return window on Amazon. I also have other problems with this router on devices like the Ulephone Armor 8 Pro will connect once to the Wifi and will never reconnect to the wifi unless the phone is rebooted.
