WEP is a network feature
WEP is an optional wireless network feature. Not all wireless networks use WEP.
Configure the printer for WEP only if the printer's network uses WEP. The printer's
WEP settings must match the network's settings. If your network has WEP, you
must use an Ethernet cable to connect the printer to the network in order to install
the printer software.
If the printer's network does not use WEP, then do not configure the printer to use
WEP.
If you do not know if your network uses WEP, consult the configuration utility for
your computer's NIC card or your network's
Wireless Access Point (WAP)
