Intellinet Network Solutions 523967 - Manual (Page 68)

DTIM Period(4): Set the DTIM period of the wireless radio. Do not
modify the default value if you don't know what it
should be, default value is 3.
Data Rate(5):
Set the wireless data transfer rate to a specific value.
Since most of wireless devices will negotiate with
each other and pick a proper data transfer rate
automatically, it's not necessary to change this
value unless you know what will happen after
modification.
N Data Rate(6):
Same as above, but only for 802.11n clients.
Channel Width (7): Set the channel width of wireless radio. Do not
modify default the value if you don't know what it
should be, default setting is 'Auto 20/40 MHz'.
Preamble Type (8): Set the type of preamble, do not modify default
value if you don't know what it is, default setting is
'Short Preamble'.
Broadcast ESSID (9): Decide if the wireless router will broadcast its
own ESSID or not. You can hide the ESSID of your
wireless router (set the option to 'Disable'), so only
people who know the ESSID of your wireless router
can connect to it.
CTS Protect (10): Enabling this setting will reduce the chance of radio
signal collisions between 802.11b and 802.11g/n
wireless access points. It's recommended to set this
option to 'Auto' or 'Always'. However, if you set to
'None', your wireless router should be able to work
fine, too.
Tx Power (11):
You can set the output power of the wireless radio.
Unless you're using this wireless router in a really
big space, you may not have to set output power to
100%.
