Option Description
Band
ThenewamendmentallowsIEEE802.11gunitstofallbacktospeedsof11Mbps,
soIEEE802.11bandIEEE802.11gdevicescancoexistinthesamenetwork.The
twostandardsapplytothe2.4GHzfrequencyband.IEEE802.11gcreatesdata-
rateparityat2.4GHzwiththeIEEE802.11astandard,whichhasa54Mbpsrateat
5GHz.(IEEE802.11nhasotherdifferencescomparedtoIEEE802.11borg,suchas
offeringmorechannels.)
Channel
Drop-downmenuthatallowsselectionofaspecificchannel.
Auto Channel
Timer (min)
Autochannelscantimerinminutes(0todisable)
802�11n/EWC
Withdrop-downmenu,“Auto”isfor11nand“Disable”isfor11g
Bandwidth
Drop-downmenuspecifiesthefollowingbandwidth:20MHzand40MHz.
Control
Sideband
Thisisavailablefor40MHz.Drop-downmenuallowsselectinguppersidebandor
lowersideband
802�11n Rate
Drop-downmenuspecifiesthefollowingfixedrates.Themaximumratefor
bandwidth,20MHz,is130MHzandthemaximumbandwidth,40MHz,is270MHz
802�11n
Protection
Itissimilaras802.11gprotection.InAutomodetherouterwilluseRTS/CTSto
improve802.11nperformanceinmixed802.11n/802.11g/802.11bnetworks.Turn
protectionofftomaximize802.11nthroughputundermostconditions.
Support 802�11n
client only
Drop-downmenuallowsselecting“On/Off”.Choosing“On”allowstheclientwith
11nonlytoconnect,notfor11gor11b;choosing“Off”allowstheclientwith
11n/11g/11btoconnect
54g Rate
Drop-downmenuthatspecifiesthefollowingfixedrates:Auto:Default.Uses
the11Mbpsdataratewhenpossiblebutdropstolowerrateswhennecessary.
1Mbps,2Mbps,5.5Mbps,or11Mbpsfixedrates.Theappropriatesettingis
dependentonsignalstrength.
Multicast Rate
Settingmulticastpackettransmitrate.
Basic Rate
Settingbasictransmitrate.
Fragmentation
Threshold
Athreshold,specifiedinbytes,thatdetermineswhetherpacketswillbe
fragmentedandatwhatsize.Onan802.11WLAN,packetsthatexceedthe
fragmentationthresholdarefragmented,i.e.,splitintosmallerunitssuitablefor
thecircuitsize.Packetssmallerthanthespecifiedfragmentationthresholdvalue
arenotfragmented.Enteravaluebetween256and2346.Ifyouexperienceahigh
packeterrorratetrytoslightlyincreaseyourFragmentationThreshold.Thevalue
shouldremainatitsdefaultsettingof2346.SettingtheFragmentationThreshold
toolowmayresultinpoorperformance.
RTS Threshold
RequesttoSend,(whensetinbytes)specifiesthepacketsizebeyondwhichthe
WLANCardinvokesitsRTS/CTSmechanism.Packetsthatexceedthespecified
RTSthresholdtriggertheRTS/CTSmechanism.TheNICtransmitssmallerpacket
withoutusingRTS/CTS.Thedefaultsettingof2347(maximumlength)disables
RTSThreshold.
