Problem with high latency/ping
Hello all. We received our 5g Gateway two days ago and so far, have big problems. We've been testing our latency and speeds over and over at https://www.speedtest.net and have observed the latency/p...
Multiple things in play that contribute... the upper layers are a mess because of their XLAT464/CGNAT crud. Can't really do anything about that.
Their peering is pretty bad sometimes as well... can break 100mbps with decent ping to something like cloudflare, then turn around and hit others in the same city and it struggles to hit 60 with jitter all over the map.
One thing you could try is manually setting the MTU. May eliminate at least one potential hiccup if you are throwing 1500 bytes out and it is having to break them down into two packets. May want to test it to confirm what yours is actually running with. 1420 should be safe, but you MIGHT be able to pass 1440... so may want to check it with no defrag bit set on some pings to be sure.
