AI agents are no longer limited to answering questions or writing code. In this experiment, Codex independently installed Tessabyte, discovered the command-line syntax, and performed real TCP/UDP network tests against local and cloud servers — all from a plain-English prompt. This is not consumer “speed test” automation. It is the beginning of intent-driven network testing.

External 10G Ethernet adapters promise easy upgrades to multi-gig speeds, but do they actually deliver? We tested USB and Thunderbolt 10G adapters in a controlled lab setup and found a mixed picture. Some devices reached near line-rate TCP throughput, while others struggled badly. Even more interesting, UDP performance lagged far behind. Here’s what’s really going on under the hood.

How many Wi-Fi clients can a single access point really support? The answer isn’t as simple as a number. In real networks, every device competes for the same airtime, and as more clients join, each gets a smaller slice of the pie. In this article, we look at how Wi-Fi capacity actually works — and why adding “just a few more devices” can quickly turn a fast network into a slow one.

If you have ever validated a Wi-Fi upgrade in a quiet lab and then spent the next week explaining to users why “everything looks fine on our end,” you already know how this story ends. The lab test measured the PHY at its best. The real network lives and dies by airtime. This post is for Wi-Fi engineers. It is about understanding why that number collapses at 10:30 AM on a Tuesday, and how to test in a way that predicts what users will actually experience.
