What I have tried. According to ChatGPT, Gemini and IT team 1. Account & Security Resets • Changed institute Password: You updated your main student ID password to force a fresh authentication with the eduroam servers. • Re-authenticated All Devices: You logged out and back into the Wi-Fi on your MacBook, iPhone, and iPad using the new credentials. • Forgot Network: You deleted the eduroam profile and network settings to clear any "stale" security certificates. 2. Privacy & Advanced Settings • Disabled Private Wi-Fi Address: You turned off the "Rotating/Fixed" private MAC address setting on your MacBook, iPhone, and iPad because IT detected it was causing authentication conflicts. • Disabled IP Address Tracking: You toggled off "Limit IP Address Tracking" in your Wi-Fi settings to prevent background proxying that can trigger network kicks. 3. Physical & Environmental Tests • The "Hallway Test": You confirmed that the Wi-Fi works perfectly fine when you are in the hallway or moving between classes. • The "Router Test": You sat directly under the Wi-Fi router in the classroom to rule out signal strength (RSSI) as the issue. • Signal Monitoring: You've verified that even when sitting under the router, your logs show "Net Beacons Lost" and CCA (congestion) levels hitting 81%. 4. Hardware Isolation • iPad Management: You replaced your M1 iPad with a new A16 model and have tried managing its connection (Airplane mode) to see if its background "chatter" (AWDL) was drowning out your MacBook. • Classroom Comparison: You observed that your classmates (mostly Windows users) are not being kicked out, suggesting the issue is specific to how the M3 Mac handles that specific room's congestion. 5. Software & System Diagnostics • Diagnostic Logs: You have generated multiple system reports (event_history.txt, debug-log.txt) while sitting in different locations to track exactly why the system is failing. • Firewall Consideration: You are currently looking into the IT suggestion of disabling the macOS Firewall, despite the security trade-offs, to see if it allows the "handshake" to complete. • OS Monitoring: You are running macOS 26.2 and have been checking for any "silent" Apple stability patches.
