AirRouter User Guide
•
Noise Floor
Displays the current value of the noise
level in dBm. Noise Floor is taken into account while
evaluating the signal quality (Signal-to-Noise Ratio SNR,
RSSI) while value mean depends on signal strength
above the noise floor.
•
CCQ
Value represents the quality of the connection to
the Access Point.
•
Tx/Rx Rate
Represents the data rates of the last
transmitted and received packets.
•
Tx/Rx Packets
Displays the total number of packets
transmitted and received during the connection.
•
Tx/Rx Packet Rate (packets per second)
Represents
the mean value of the transmitted and received packet
rate.
•
Bytes transmitted/received
Value represents the total
amount of data (in bytes) transmitted and received
during the connection.
•
Negotiated Rate/Last Signal (dBm) table
Values
represent the received wireless signal level along with
the all data rates of recently received packets. “N/A”
value is represented as the Last Signal if no packets were
received on that particular data rate.
To reconnect to the AP press the Reconnect button,
in order to reestablish the wireless link. The list can be
updated using the Refresh button.
DHCP Client
(Applicable for Router and SOHO Router in DHCP mode
only.) Shows the device’s WAN IP address, Netmask, DNS
servers and Gateway while operating in DHCP Router
mode.
IP Address
Displays the device’s WAN IP address while
operating in DHCP Client mode.
Netmask
Displays the device’s netmask when operating
in DHCP Client mode. It is assigned automatically by the
DHCP server (not the AirRouter’s DHCP server), which
assigns the WAN IP address to the device.
Gateway
Displays the device’s gateway when operating
in DHCP Client mode, which is assigned automatically by
the DHCP server (not the AirRouter’s DHCP server).
Primary/Secondary DNS IP
Domain Name System (DNS)
is an Internet “phone book” which translates domain
names to IP addresses. These fields identify the server IP
addresses that the AirRouter uses for translation.
DHCP Server
Displays the IP address of the DHCP Server
assigning the WAN IP Address to the AirRouter.
Domain
Displays the domain name.
Total Lease Time
Shows the total time (validity) of the
leased IP address assigned by the external DHCP server.
Remaining Lease Time
Displays the remaining time of
the IP address leased by the external DHCP server.
ARP table
Lists all the entries of the ARP (Address Resolution
Protocol) table currently recorded on the device.
ARP is used to associate each IP address to the unique
hardware address (MAC) of each device. It is important to
have unique IP addresses for each MAC or else there will
be ambiguous routes in the network.
IP Address
Displays the assigned IP address.
MAC Address
Displays the MAC address of the device.
Interface
Displays the interface that the device is on.
The list can be updated using the Refresh button.
Bridge Table
Displays the entries in the system bridge table when the
device is operating in Bridge mode.
The list can be updated using the Refresh button.
The Bridge table shows which bridge port the particular
station is associated with - in other words from which
interface (Ethernet or wireless ) the network device
(defined by MAC address) is reachable from. The AirRouter
will forward the packets to that port only (thus saving a lot
of redundant copies and transmits).
The aging timer shows the aging time for each address
entry (in seconds) - after particular time out, not having
seen a packet coming from a certain address, the bridge
will delete that address from the Bridge Table.
Routes
Lists all the entries in the system routing table, while the
device is operating in Router mode.
The list can be updated using the Refresh button.
AirOS examines the destination IP address of each data
packet traveling through the system and chooses the
appropriate interface to forward the packet to. The system
choice depends on static routing rules – entries, which
are registered in the system routing table. Static routes
to specific hosts, networks or default gateway are set up
automatically according to the IP configuration of all the
AirOS interfaces.
