WiFi: The Invisible Tether
The Instructor's Perspective
In the Army, we learned about “signal discipline.” WiFi is convenient, but it’s also a shared medium. If you’re using it for everything, your performance will suffer. In our labs, we’re using things like Ubiquiti UAP-AC-PRO or other enterprise-grade access points to ensure we have a reliable, segmented wireless network.
Why use it?
- Mobility: Convenience for devices that aren’t bolted down (e.g., your student laptops).
- Segmentation: Creating a separate “Guest” or “IoT” SSID to keep those devices away from your core lab infrastructure.
- Reach: Getting connectivity into those awkward corners where you can’t run a cable.
WiFi Reliability (The PACE Plan)
Connectivity Discipline
P (Primary): Dedicated hardware Access Points (e.g., Ubiquiti/TP-Link Omada). A (Alternate): Integrated WiFi on your main Router. C (Contingency): Mobile hotspot for emergency management access. E (Emergency): Ethernet cable (The ultimate “No-WiFi” fallback).
Standard Operating Procedure (SOP) Best Practices
- WPA3/WPA2-AES: Always use the strongest encryption available. Avoid WPA or WEP at all costs.
- SSID Separation: Keep your “Lab” traffic separate from your “Personal” traffic.
- Firmware Updates: Access points are internet-facing. Keep them updated.
Check for Understanding
- Why should we avoid using a single SSID for both our lab and our guests?
- If the WiFi goes down, what is the fastest way to regain access to your Proxmox node?
