Initial Setup
Begin by nding a good place to set up your router/access point.  Some things to
consider:
•You’llneedtobeabletoplugyourinternetconnectionintoit,soitshouldgowithin
reachoftheLANcablefromyourDSLorCablemodem.You’llalsowantapoweroutlet
nearby.
•Keeptheaccesspointascentralinyourworkareaaspossible.Signalstrengthand
speed fall off with distance.
•Higherisoftenbetter.Forinstance,setituponthetopshelfofabookcaseratherthan
thebottomone,ifpossible.
•Theantennausuallyworksbestiforientedtopointstraightup.
Doyouneedapasswordorotherinformationtologintoyourinternetconnection?
ManyDSLconnectionsrequireinformationlikeglobalIPaddress,subnetmask,default
gatewayaddress,DNSserveraddress,orPPPoEparametersinordertoconnect.Cable
modemsusuallydon’trequireextrainformation.If
youhaveaDSLinternetconnection,makesure
that you have any necessary information
handybeforeyoucontinue.YourInternet
ServiceProvidercangiveyouthis
informationifyoudon’tknowit.

you’veconnectedtotheinternetthroughtherouter,youmayswitchtoawireless
connection if desired.
ThecomputerusedtoconguretheAirStationshouldbesettoobtainanIPaddress
automaticallyusingaDHCPserver(thisisWindows’default).TheWHR-G125hasa
defaultLANIPaddressof192.168.11.1andSubnetMaskof255.255.255.0.
1.PowerdowntheCableorDSLmodemandthecomputerwhichwillbeusedto
conguretheAirStationrouter.
2.PlugtheCableorDSLmodem’sEthernetcableintotheAirStation’sWANport.
Initially,youmayneedtounplugthiscablefromyourcomputer,huborotherrouter.
3.PlugtheprovidedEthernetcableintoaLANportontheAirStationandplugtheother
endintoyourcomputer’sEthernetadapter(NIC).
4. Important: turn everything on in the correct order!! PoweronyourcableorDSL
modemandwaitonefullminute,thenpowerontheAirStationrouterandwaitone
fullminute,andnallypoweronthecomputerwhichwillbeusedtocongurethe
AirStation.

About 15 seconds later, you’ll have a

Some things to keep in mind with AOSS:
•OnlyoneAOSSwirelessclientadaptercanbeconguredwiththeAOSSrouterata
time.Thebuttonswillneedtobere-pressedtoconnecteachadditionalAOSSwireless
client adapter.
•ItisnotnecessarytoAOSSclientdevicesthathavealreadybeenconguredviaAOSS,
unlesssignicantchangeshavebeenmadetothewirelessnetwork.
•DonotattempttoconguretwoseparateAOSSnetworksatthesametime,asitmay
causeundesiredcongurations.
•IfanundesiredclienthasconnectedviaAOSS,itcanbedisconnectedfromwithinthe
WHR-G125’scongurationGUI.
AOSS Notes

17
ThisAirStationsupportsquicklychangingthe
product from a wireless router to a conventional
access point.
Fornormaluse,leavethe“Router”switchintheON
position.
IftheRouterswitchismovedtoOFF,thedefaultIP
addressoftheAirStationchangesfrom192.168.11.1
to192.168.11.100,andDHCP,NAT,andtheWAN
portaredisabled.
Turningthisswitchoffmightbedesirableifyou’re
addingwirelesscapabilitytoanexistingnetwork
witharouter.Itisnotsuitableformosthomecongurations.Ifyouplantousethe
AirStationasannormalwirelessrouter,makesurethatthisswitchisinthenormal(ON)
position!

Bydefault,encryptionisnotenabledonthe
AirStation unless you used AOSS to perform your
setup.Anyonewithinrangecaneasilyconnectto
yourwirelessnetwork.Thismightnotbewhatyou
want.
Buffalorecommendsenablingencryptionand
settingapasswordforaccesstoyournetwork.This
iseasytocongurefromwithintheAirStation’s
congurationtool.SelecttheWireless Congtab
and the Securitysubmenu.Usethestrongestformof
encryption that all of your clients support.
Encryption and Security

19
Manykindsofencryptionareavailable.WEP
workswithalmosteverything.WPA2-PSKis
muchmoresecure.Choosethestrongestmethod
ofencryptionthatworkswithallofyourwireless
devices.
IfyoumustuseWEP,itisavailableunder“Wireless
Encryption”.
Enteranetworkkey(“password”)forthis
connection. Write down your password and put
itinasafeplace.Youwillnotbeabletoconnect
wirelessdevicestoyournetworkwithoutthis
password.
