Thisguidepresentsthedescriptionof thesubscriber stations LiteStation2,LiteStation5
and theoutdoorwirelessstationPowerStation2.
LiteStation2andPowerStation2 operateinIEEE802.11b/gmodes,whilethe
LiteStation5operates inIEEE802.11amode.Thedevicescanoperatein Client
(Station),AccessPoint andWDSmodes.Thescreenshots inthismanualaremadefor
PowerStation2 but theyare alsoapplicablefor LiteStaiton2and LiteStaiton5.

QuickSetupGuide
ThisQuickSetupGuidewillguideyou throughquick andeasyconfigurationof the
subscriberstation(clientbridge) including:
ChangingoftheIPsettings (staticordynamic),
DefiningtheSSIDtowhichthesubscriberstationwillbeassociated,
Definingthe IEEE802.11mode,
Definingthe wirelesssecurity(None,WEP,WPA™or WPA2™),
Changingthe administrator’s password.
Fordetailedsetup and configurationinstructions,pleaserefer tothechapter
Configuration Guide.
Follow thesestepsforsubscriberstationquick setupviaweb-browserinterface:
Step1Login totheweb management
Open thewebbrowser andtype thedefaultIPaddress ofthe
PowerStation2/LiteStation2/LiteStation5device http://192.168.1.20/ intothe browser
addressfield. You willbe prompted toenter the administrator logincredentials:
UserName: ubnt
Password: ubnt
Aftersuccessfuladministrator logonyouwillseethemainpage ofthesubscriberstation
webmanagementinterface.
Step2Configurenetworksettings
TheIPconfiguration asdescribed below is requiredfor
PowerStation2/LiteStation2/LiteStation5 managementpurposes.IPaddressescan either
beretrievedfromaDHCPserveror configuredmanually.
Usethe Network menu toconfiguretheIPsettings:
NetworkMode: specifythe Bridge operatingmode(selected bydefault). Router
operating modeconfigurationis described inthechapter Configuration Guide.
