Question

Clinic tablets receive Access-Accept from RADIUS, yet the 4-way handshake fails and no user-plane traffic flows. Conceptually, what should the municipal WLAN team investigate first among AKM issues?

Accepted Answer

AKM suite or pairwise-cipher mismatch between client and AP after AAA success, preventing key confirmation in the 4-way handshake — RADIUS said “you’re good,” but the 4-way still face-planted—that’s usually the lock types not matching after the bouncer waved you through. Check AKM/cipher negotiation, not the thermostat or DNS trivia first.

Answer

Whether the building’s HVAC setpoints are within the AP operating temperature datasheet

Answer

Whether DNS scavenged the tablet’s PTR record before association

Answer

Whether the captive portal’s TLS certificate uses RSA-512 for the splash page only
