I've done everything possible—reset, tweak router settings, etc. It's a 250-foot Cat5e run with chain-linking routers. Speeds are normal or better on both sides, but upload latency spikes between 200 and 450 ms anywhere. I've tried shortening the cable, changing cables, adjusting settings, but nothing helps. If anyone has a solution, please let me know—I'm really exhausted from this.

Did you check that your link and connections are solid? Make sure your eyes are clear—no objects in the way—and inspect the whole wire for any cuts or damage. Good luck!

Are you maxing out your ISP's upload bandwidth? That's a sure fire way to get lowsy upload ping, caused by buffer bloat. QoS/SmartQueue can be configured for some routers to set a cap on upload speeds and prioritize traffic and prevent this. Start with setting it to 90% of max upload and adjust from there. You can do a before & after buffer bloat test using various sites online. Speedtest.net tends to at least give down & up ping times, but not bufferbloat ratings.
