Don’t Ghost Your Wi-Fi. Why Post-Deployment Checkups Matter

Rolling out a new Wi-Fi network feels like crossing the finish line, but in reality, it’s more like the halfway point. Following up after deployment is where the real value shows up. It’s your chance to confirm that access points are behaving the way you intended, coverage is consistent, and users are actually getting the performance you designed for. Without that follow-up, small issues can quietly grow into big complaints later.

In the image I shared, it’s pretty obvious that users aren’t evenly distributed across the access points. One AP looks loaded while others are just hanging out, bored and underutilized. That imbalance might be due to AP placement, building layout, or client devices stubbornly sticking to a stronger-looking signal. Even if it’s “technically working,” it’s still worth digging into because uneven client distribution can tank performance for everyone connected to the busy AP.

From the web - Chris Greer and Dont Break DNS

Dive into the often-misunderstood world of DNS with **“Don’t Break DNS!! // Lesson 2”** from networking expert Chris Greer. While many assume DNS runs exclusively over UDP, this eye-opening episode in the "How DNS Works" series reveals the critical role TCP plays when responses grow too large for UDP packets. Using real-world examples and Wireshark packet captures, Chris demonstrates exactly what happens when a UDP reply gets truncated (the infamous TC flag), forcing the client to retry over a TCP connection. Whether you're troubleshooting mysterious resolution failures or simply want to deepen your understanding of core internet protocols, this lesson delivers clear, practical insights backed by key RFCs like 1123 and 5966.
