Good evening, sorry if I didn't reply before, but I was at the playground with the kids!!! So I'll start with the discussion, the Netduma R3 is directly connected to the ONT!!! With PPOE connection!!! My fiber optic speed is 2.5 GB down and 1 GB up. Since the R3 is limited to 1 GB down\up, doing a lot of tests, the best connection was when I entered 800 down and 800 up for the speeds!!! With these values I was having a great time in gaming!!! Obviously the R3 connection to the PC and PS5 is via Cat8 internet cable!!! As DNS I put Google's 8.8.8.8 primary and 8.8.4.4 secondary which work fine!!! The smart boost is set only to Gaming!!! The firmware version is 4.0.540!!! Another thing that is no less important, on the net dumaweb page I remember very well a message about this problem here, which unfortunately I did not have time to read!!!
