I decided this is not a Snap! or 2 Degrees problem, it is an "any other router" used with Snap! 2 Degrees UFB problem.
I don't like the 7390, I have used it for 3 years from ADSL to VDSL and UFB. My Xbone constantly has moderate NAT so I changed to a Netgear Nighthawk R8000.
I can only get 100Mbps up and down through it using speedtest. I know my line speed with speedtest and the 7390 is 200+ up and down.
Is there anything I can do with my R8000 to get the full bandwidth or am I stuck with the Fritz?
I also tried another router a Dlink AC750 and got the same 100Mbps max throughput.
Interestingly at my Xbone doing a network speed test I get with the Dlink 50 down 60 up and with the R8000 80 down 40 up. Consistent testing also. Everything is RJ45 wired no Wifi.
Any ideas anyone?
