Michiel - my results are similar to yours on the Speedflex app on iOS, but I am getting over 500Mb upload and download on the Ookla Speedtest iOS app on my 1Gb fibre connection. Before the firmware update, Speedtest was consistent with Speedflex (rarely over 100Mb download). Would be curious if your external test or real-world speeds have improved more than Speedflex suggests.
