The maximum transfer rate, as outlined in the IEEE 802.11n standard, for networks using WEP or WPA (TKIP) passwords is 54 Mbps (megabits per second). To ensure that you are getting the best speeds from your 802.11n router or Base Station, be sure you are using the WPA2 password configuration. You may also choose to have no password protecting your network, though security risks obviously increase with that choice.
By default, Apple's AirPort Utility (Applications > Utilities) does not allow users to configure their Apple router (Base Station, Express, or Time Capsule) with a WEP or WPA password. Keep in mind, third-party routers may not have the option for WPA2 passwords. Check the manufacturer's Web site for more information on your specific router.
The best password choices for your 802.11n router are the WPA/WPA2 Personal option or the WPA2 Personal option.
- WPA/WPA2 Personal will have the fastest transfer rates when only one device (unicast) is being served. When other devices are using the network, they will run in multicast at 54 Mbps.
- WPA2 Personal will provide the best 802.11n transfer rates and is recommend for the majority of users.
