Hi Mo, I have the latest hardware (gray cylinder) -- Typically 3 of 5 bars 4G Band: B2 5G Band: n71 -- Note the huge jitter only occurs inbound, which is difficult to measure without using WireGuard. The same UDP iperf3 tests outbound (gw-lan->linode) range from 3 to 8 ms jitter, regardless

Thanks for sharing, I have also been running WG tunnels over T-Mobile home internet and haven’t seen any of the jitter you are reporting. Did you try the same tests (outbound) without running them via WG? Which modem do you have? How many signal bars are you getting? Also, what does an

Greetings, I have been testing the T-Mobile Home Internet (4G/5G fixed wireless) service to a Linode VM via WireGuard. The TMHI service uses CGNAT plus an additional NAT in their modem/gateway with a MTU of 1420, so WireGuard is configured with a 1340 MTU. Everything works, but I thought I
