Select WEP Key Length from the drop-down menu. (128 bit is stronger
than 64 bit)
Type strings to define these 4 keys for each on WEP Key 1/2/3/4.
Choose which WEP key from 1 to 4 you want to use to link to clients on
the Default WEP Key.
Select Authentication type from the drop-down menu. (Shared is
better than Open)
Click on the Apply Settings button to apply settings.
