Ethernet speed after DECO limited to 500
My internet connection is fiber with 1000 up/down.
Modem is connected via a CAT 6 cable to the DECO M5.
Connection to my PC is via a CAT 6 cable.
When I connect my PC directly to the modem and run a speedtest I get something near the 1000.
When I run the speedtest on the DECO itself I get something like 850.
When I connect my PC on the other port of the DECO M5 and run a speedtest i get something below 500.
So it looks like that although the DECO M5 has two gigabit ports, it's limited to 500?
Is there any solution? Do all the DECO models have this problem?
