If you have a mixed mode network,
with both 802.11b and 802.11g clients,
it’s recommended that you check 11g

clients don’t hog all available bandwidth.
Only change the Multicast Rate and
DTIM settings if told to do so by your

Channel Expansion reduces wireless
overhead by taking advantage of
additional channels for network traffi c

must be enabled and confi gured
properly for maximum throughput to be
achieved.
