6.2.4 Fragmentation Threshold
A Fragmentation Threshold is the maximum data fragment size (between 256 and 2432
bytes) that can be sent in the wireless network before the ZyXEL device will fragment the
packet into smaller data frames.
A large Fragmentation Threshold is recommended for networks not prone to interference
while you should set a smaller threshold for busy networks or networks that are prone to
interference.
If the Fragmentation Threshold value is smaller than the RTS/CTS value (see previously)
you set then the RTS (Request To Send)/CTS (Clear to Send) handshake will never occur as
data frames will be fragmented before they reach RTS Threshold size.
6.2.5 WEP
WEP provides a mechanism for encrypting data using encryption keys. Both the AP and the
wireless stations must use the same WEP key to encrypt and decrypt data. The ZyXEL device
allows you to configure up to four 64-bit or 128-bit WEP keys, but only one key can be
enabled at any one time.
6.3 Configuring Wireless LAN
If you are configuring the ZyXEL device from a computer connected to the wireless LAN and
you change the ZyXEL device's ESSID or WEP settings, you will lose your wireless
connection when you press Apply to confirm. You must then change the wireless settings of
your computer to match the ZyXEL device's new settings.
Select a device, and then click Configuration > WLAN. Wireless is the first screen.
