FAQ
Q：How do I configure the Key?
A：As shown in figure 4-3, the security mode used when ESSID is 1 is WEP and uses
WEP Key 1 as its default key. The user would need to configure the key to be
corresponding to the key on the wireless router. For example, if the WEP key set on
the wireless router is set to 123456, configure the WEP Key1 to 123456. Press F3 to
save the settings. If both the configurations and the key are correct, the user should
be able to connect to the Wifi network in a few seconds. Users can also configure the
keys from the web configuration interface (see figure 4-4 below).
