The client expired time determines time interval the client need to re-associate with the
device while client is idle. The default client expired time is 300 sec.
MTU Size
Maximum Transmission Unit, the default MTU size is 1500. The MTU setting controls the
maximum Ethernet packet size your PC will send. Why a limit? Because although larger
packets can be constructed and sent, your ISP and Internet backbone routers and
equipment will fragment any larger than their limit, then these parts are re-assembled by the
target equipment before reading. This fragmentation and re-assembly is not optimal. You
may need to change the MTU for optimal performance of your wireless LAN traffic.
Data Rate
The standard IEEE 802.11b/11g supports 1, 2, 5.5, 11 / 6, 9, 12, 18, 24, 36, 48 and 54 Mbps
data rates. You can choose the rate that the device uses for data transmission. The default
value is “auto”. The device will use the highest possible selected transmission rate.
Preamble Type
The preamble is part of the 802.11 frame and is PHY dependant. All 802.11b/g systems
support the long preamble. The short preamble (optional) maybe used to improve
throughput when all stations on the network support the short preamble.
Broadcast SSID
Broadcasting the SSID will let your wireless clients find the device automatically. If you are
building a public Wireless Network, disable this function can provide better security. Every
wireless stations located within the coverage of the device must connect this device by
manually configure the SSID in your client settings.
IAPP (Inter-Access Point Protocol)
This function will let Wireless Stations roam among a network environment with multiple
devices. Wireless Stations are able to switch from one device to another as they move
between the coverage areas. Users can have more wireless working range. An example is
as the following figure.
You should comply with the following instructions to roam among the wireless coverage
areas.
Note
：
For implementing the roaming function, the setting MUST comply the following two
items.
All the devices must be in the same subnet network and the SSID must be the same.
If you use the 802.1x authentication, you need to have the user profile in these devices
for the roaming station.
