Deco M4 wired connection is slow
I have bought the tripple unit version of the Deco M4 system. I see some weird slow speeds when connected wired to the main unit.
I have a 1 Gigabit internet connection.
When connected wired to my previous router, I have speeds between 700 - 800 mbit, however when connected via the Deco M4 main router unit, I see the speeds between 250 - 450 mbit.
My wired connection configuration:
modem -> deco m4 main router -> PC
What can be done?
I already defined the QoS to 1000 mbit download and 100 mbit upload, and defined my PC as high priority device.
