A device that fails to meet the demands of its intended era may perfectly meet the demands of a future era. The WAP that couldn’t handle thirty Zoom calls in 2010 can handle thirty temperature sensors in a greenhouse in 2026. The radio that dropped every third packet in an office drops zero packets when it’s the only radio in a concrete bunker.

Unlike the rugged and easily repairable WAP-4 or the standardized WAP-7, the WAP-15 required specialized components that were often caught in supply chain bottlenecks. After 15 years, many of these units have spent more time in the shed for "unusual" technical failures than on the tracks. This inconsistency made it a "bad" choice for time-critical premium trains like the Rajdhani or Shatabdi Express. 3. The "Jack of All Trades" Problem

Configure the radio in “monitor mode” or “adhoc mesh.” Define a static IP. Walk away. That “bad” WAP, now 15 years new, will run for 400 days without a reboot.

Here’s a short, interesting review for a “bad WAP” that’s now 15 years old—focusing on nostalgia, frustration, and the passage of time.
