Explanations

If you are using EpsonNet 802.11g Wireless
Ext. Print Server in the Ad Hoc mode, you
cannot use WPA-Personal (TKIP) for the
security level.

System, Shared Key, or Automatic.

(TKIP) is selected for the security level.)
Select this check box to set the WEP Key in
hexadecimal.
When you select 64 bit(40 bit) for the length,
you can set up to 4 WEP Keys. When you
select 128 bit(104bit), you can set only one
WEP Key.

enabling use of encryption.
