Post-incident Sumary

Hacker News Discussion

To summarize this post, I was seemingly throttled by AT&T for days. See the Original Post for the full write up.

While gathering data for this post and attempting solutions, I changed my LTE router’s APN, which caused it to re-authenticate to AT&T, and after I was re-authenticated I was no longer being throttled. One Hacker News user suggested that re-authenticating may have caused me to route through a different PGW (Packet Data Network Gateway) with a different traffic shaping policy.

After figuring out a problem after hours of struggle, the simplicity of the result often belies the difficulty of the process. When I look at the final configuration that I came up with in ACEManager, everything looks simple and obvious, but the process was far from it. That’s the case nearly every time I configure a new feature on my Sierra Wireless RV55 LTE router. This device is not made for consumers. It’s built for ambulances, traffic lights, Greyhound buses, remote gas pipelines, and their ilk. Not bozos like myself boondocking in their RVs. Lucky for me, I know my way around this thing pretty well now.
