iPad Interoperability Considerations
Support Weak Opmodes• To support WEP/TKIP “allow weak
encryption” or iPad will not connect
Enhanced Roaming• Validate PMKID should be enabled for all
Apple clients
Strong (WPA2) Recommended• WPA2-AES EAP-TLS requires iPhone
configuration utility kb/dl926 & kb/DL851
• Root & client cert for auth
Stateful Firewall & Multicast • Drop broadcast/multicast or limit
applications like Bonjour, iTunes, other peer-to-peer apps
