Product and Software: This article applies to the Symbol PPT8800 with the latest level of drivers.
When we input a passphrase, the Symbol PPT8800 generates a preshare hex key. This works fine, but the handheld will not associate and authenticate with the APs. If you use a simple passphrase, the PPT8800 will be able to connect to the AP.
The only way to use a complex passphrase is to generate a hex key with an offline tool and manually input the hex key into the handheld. It looks like the Symbol device cannot process the key correctly. For big retail deployments, the administrator can replicate the register to multiple devices.
