Having some pretty bad latency issues with my GL-X3000 router. I am connected via lan directly teo the router which is using the Calyx card cellular 5g network. Getting Download speeds from 100-500 mbps and Upload of 50-100mpbs. But my latency at the same time is showing an average of 200+. I have tried adding SQM and adjusting the wan (eth0) to lower speeds, tried switching ttl to 65, tried turning on the cone but nothing I have done has made any difference on the ping/latency. Any other recommended steps I could take to get the latency down to under 100 at least? ---

Have you tried the Calyx sim card in a phone? I’ve used my GL-X3000 with AT&T, T-Mobile and Verizon MVNO’s and get good sub-50 latency values with each carrier. Are you using a VPN when testing? ---
