After CenturyLink/QuantumFiber/AT&T replaced our fiber terminal, and I replaced our wi-fi router, things seem to have gotten a bit more stable.

However, we are still having these occasional slowdowns for around 30 seconds, where everything becomes choppy and latency jumps up.

I just captured one that lasted 36 seconds, so I know I am not imagining it. I just wish the fiber company had any idea what was going on.

Downloaded #PingPlotter to monitor what is happening with my #ATT / #QuantumFiber / #CenturyLink fiber service, and wow, is #LumenTech (the part of CenturyLink that didn't go to AT&T) really losing 85-90% of packets between Portland and Seattle?

I don't think this is our problem, but #LumenTech admitting that their network just can't cope with MAC addresses that start with a 4 or 6 is one of the most unhinged things I have ever heard.

Resolving throughput issues

Learn how to resolve throughput issues related to your MAC address. If your MAC address begins with a 4 or a 6, this could contribute to packet reordering over your Lumen service—which may cause slow speeds.

@mikemccaffrey very old problem. it's been a reasonably well known hashing issue in all sorts of kit over the years.

@sulrich I'll just be sitting over here with my face in my palms for a little while.
