        HI,

         

        The Router is connected to a TPLink TL-R470T+ Hub, connected to 4G Box

        The R7800 router's firmware is V1.0.2.90

        The EX7300 Extender's firmware is 1.0.0.146

         

        I don't really know what is the connexion when it happens. It seems both was I'm either closer to the router or the extender..

         

        Thank you
