802.11Mode
RLX2‐IHNF
ThiscontrolisonlypresentontheRLX2‐IHNFmodel.Itallowstheunittobe
configuredtooperatein802.11a/gmodeortooperatein802.11nmode
(default).Inaddition,itallowsconfigurationofwhethertheunitwillallow
useof40MHzwidechannelsforChildcl
ients.
Note:TheParentradiolinkofaRepeaterautomaticallyusesamodethatis
compatiblewiththeParentsettings.Forexample,anRLX2‐IHNFmayconnect
toanRLX2‐IHWmasterwhichonlyoperatesin802.11a/gmode,andstilluse
802.11nmodeforanyChildRepeaters.

802.11a/g
Theradioactsasan802.11aradioonthe5GH
zband,andan802.11gradio
onthe2.4GHzband.Datarateswillbelimitedtothe802.11a/grates(54
mbpsmaximum).802.11noperationalfeatureswillbedisabled.Itisnot
necessarytoselectthismodeforRLX2‐IHNFradi
ostolinktootherRLX2or
RLXIBseriesradios;theywilllinktheirbestpossiblespeedsregardlessof
mode.Thismodeisnotcommonlyused.Itismainlyusedtoallow802.11
a/b/gclientdevicesthatcannotlinkto802.11ndevicestowork.Oneexample
ofsuchadeviceistheProSoft1734‐AENTRwirele
ssI/Oclient.

802.11n
DefaultoperationalmodeoftheRLX2‐IHNFradio.All802.11nfeaturesare
operational,and20MHzwidechannelsareused.

802.11.nwide
Utilizesadjacentpairsof20MHz‐widechannelsasasingle40MHz‐wide
channel.Thisallowsthefastestdatathroughputtoother802.11ndevices.
Only802.11nde
vicescanutilizethismode,butallRLX2radi oswilllinkattheir
bestspeedregardlessofmode.

Channelsinthe5GHzbandare20MHzapart,so802.11nwidemodeoccupies
onlytwochannelsinthatband.However,channelsinthe2.4GH
zbandare
spacedonlyfiveMHzapart,so802.11nwidemodeinthe2.4GHzband
occupieseightadjacentchannels!Sincethereareatmost13channelsinthe
2.4GHzband,andonlythreechannelsdonotoverlapothers,itisnot
recommendedtoenablewidemod
eon2.4GHzbandchannels.

ClickthisbuttontoconfigurearadioasaMaster.TheMasteristherootradio
inanetwork.YoumusthaveatleastoneMasterradiopernetwork.For
redundancy,youcanassignmorethanoneMastertoanetwork.For
