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 802.11a supports 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 802.11a 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)
Not applicable for WLAN 2.
802.11g Protection
Not applicable for WLAN 2.
Block WLAN Relay (Isolate Client)
The device supports isolation function. If you are building a public Wireless Network, enable
this function can provide better security. The device will block packets between wireless
clients (relay). All the wireless clients connected to the device can’t see each other.
Aggregation Mode
This is a proprietary Ralink (802.11a chipset in the DLB70xx) aggregation setting that allows
for jumbo frames consisting of multiple smaller frames that increases throughput between
Ralink stations.
Tx Burst Mode
This is a proprietary Ralink (802.11a chipset in the device) burst setting and allows very
small networks (1~3 clients) to transmit at higher speeds. In larger networks, this will result
in degraded performance.
