8.4.2.2 Encryption
This MFP Server supports WEP and WPA-PSK security mode. If
you want to use WEP encryption to protect your wireless network,
you have to select "WEP". If you want to use WPA-PSK, you have
to select "WPA-PSK" (for an infrastructure network or "WPA-None"
(enables WPA security for an ad hoc network). The wireless
security setting should be the same with other wireless devices in
the same network.
WEP Security Mode:
Key Length – You can choose "64-bit" to use WEP with 64-bit key
length encryption or choose "128-bit" to use WEP with 128-bit key
length encryption. The longer key length can provide better
security but worse transmission throughput.
