WPA2 mixed mode for Fusion on Windows mobile computers

Article ID: 28209307

Issue / Question

WPA2 mixed mode is automatically checked on newer Fusion firmware. What is it for?

Applicable To

MC32, MC92, VC70, WT41 and MC18 with CE7.

MC67,MC55E0, MC55N0, MC67NA, and MC92 with WM 6.5.3

Resolution / Answer

For WPA2 security modes, the Allow WPA2 Mixed Mode checkbox may be selected.

If this checkbox is unchecked, the mobile computer will only operate in an environment in which AES is used for encrypting both unicast and multicast/broadcast traffic. Checking this checkbox allows the mobile computer to still use only AES encryption for unicast traffic, but allows it to use either AES, TKIP, or WEP-104 encryption for broadcast traffic. This allows the mobile computer to operate with an AP that is set up to support legacy and/or WPA and WPA2 mobile computers simultaneously. Note that neither WEP-104 nor TKIP is as strong an encryption as AES, so allowing the mobile computer to operate in mixed mode is less secure.
