        for some reason those screenshots are showing. can you please post again?

         

        Can you please PM me your MAC address and the location as well and the speedtest server you are trying?

         

        also, what kind of laptop/NIC are you using?

         

        what FW are you running and I assuming ISP is comcast.

        can you please try other port on the device as well?
