WL-500W Wireless Router Quick Start Guide
If you want to protect transmitted data, select a Security
Level to enable encryption methods.
Medium: Only users with the same WEP key settings can
connect to your wireless router and transmit data using
64bits or 128bits WEP key encryption.
High: Only users with the same WPA pre-shared key
settings can connect to your wireless router and transmit
data using TKIP encryption.
For example, if we select WEP 64bits encryption mode
and input 11111 as the Passphrase, the WEP Keys are
generated automatically.
5. Click Save&Restart to restart the wireless router and
activate the new settings.
4. Input four sets of WEP keys in the WEP Key fields (10
hexadecimal digits for WEP 64bits, 26 hexadecimal
digits for WEP 128bits). You can also let the system
generate the keys by inputting a Passphrase. Record the
Passphrase and the WEP keys in your notebook, then
click Finish.
Note: We recommend using WL-100W wireless
adapters to connect WL-500W so as to achieve
high sped data transmission.
