Gigabit Fiber Upload speed gotten significantly slower since Apr 18 2025 (San Francisco)

[cronos17]

Yes, using my own gateway and an Adtran 411 ONT I believe.

[cronos17]

directly from the gateway, latency looks good.

You may want to double check. Your GW stats only show one value for latency which is probably associated with idle. Your posted results' idle values are in the expected range. Your newer results show 3 numbers, associated with idle, download, and upload.

turned of QOS and latency looks better

Thanks for the test results. We'd missed some IPv6 tuning necessary for good speedtest performance and also applied some additional NIC tuning options this morning which has improved how things look on our end too.

[cronos17]

Thank you so much for the explanation of the resolution. Glad to be a part of getting this resolved.

BTW, just reporting back on my original issue:

My upload speeds are back to NORMAL, since Apr-29:

All showing 900+ Mbps Up and Down

Anyway you can look into why my upload is high ping? Been TS this for a while and involving noc and stuff, we've just about had a tech out 3 times to swap just about everything but the drop itself even tried eero from you guys rented and direct and yeah the uploads always very wonky and will introduce several constant huge ping spikes making stuff like gaming near to impossible to accomplish.
