Earlier quoted context omitted.
If you are on ethernet, I am able to get 1-2ms pings. On same AT&T Fiber Gigabit. Wifi ruins both bandwidth and latency for me.
You should invest in some better wifi gear, it sounds like! On a Unifi nano hd, with moderate signal, my latency only goes up 1ms. Getting ~3.5 ms on wifi to 1.1.1.1, ~2.5ms ethernet
Sucks that VDSL2 no longer supports fastpath, not that I could use it on an ADSL line due to bonding anyway :/
