Configuring Advanced Wi-Fi 2.4GHz Settings
To adjust the advanced settings of the 2.4GHz Wi-Fi function, login to the hub and click on the
icon, then select Performance-2.4GHz from the menu on the left.
Note: It is only recommended that you change these settings if you are experienced and familiar with what each of these settings does.
Wi-Fi Mode: Select a mode from the drop down menu. This will affect the
wireless connection speed of your devices. Some older devices may not work
if you choose to work in 11n alone.
Enable WMM: Wi-Fi Multimedia (WMM) is Quality of Service (QoS) for your
router. Check this box to improve the quality of video and voice applications
for your wireless clients. This cannot be selected for modes where 11n is
operational.
Bandwidth: Select the frequency which you want to operate on by checking
the radio box for 20MHz or 20/40MHz.
Guard Interval: The guard interval is the space between symbols being
transmitted. It is often confused with the space between packets. Normal
802.11 operation is 800ns but with 802.11n, you may halve the time to wait
to 400ns which can increase throughput.
Tx Rate: Only modifiable if 11n Wi-Fi Mode is selected. This allows you to
specify the maximum transmission rate for the wireless network.
Tx Power: Sets the transmission power. Modifying this can help you to achieve more range on your network.
Preamble Type: The Preamble Type defines the length of the Cyclic Redundancy Check (CRC) block for communication between the
hub
and roaming wireless adapters.
Fragmentation Threshold: The 802.11 standard includes the ability for radio-based network interface cards (NICs) and access points to fragment packets for improving
performance in the presence of RF interference and marginal coverage areas. The fragment size value can typically be set between 256 and 2,346 bytes. Setting it at or
above 2,346 bytes effectively disables fragmentation.
