WDS Status
This field displays
AP
when WDS is disabled.
Bridge
when the Device functions as a wireless network bridge only
to use WDS (Wireless Distribution System) to establish wireless links
with other APs.
AP+Bridge
when WDS is enabled and the Device acts as a bridge
and access point simultaneously.
Click this to go to the screen where you can change it
AP Information
ESSID
This is the descriptive name used to identify the Device in this wireless
network. Click this to go to the screen where you can change it.
Status
This shows the current status of the wireless network.
Security
This shows the level of wireless security the Device is using in this
wireless network.
System Status
System
Uptime
This field displays how long the Device has been running since it last
started up. The Device starts up when you plug it in, when you restart it
(
Maintenance > Tools > Restart
), or when you reset it (see
Section
1.6 on page 25
).
Current
Date/Time
This field displays the current date and time in the Device. You can
change this in
Maintenance > System > Time Setting
.
System
Mode
This displays whether the Device is functioning as a router or a bridge.
CPU Usage
This field displays what percentage of the Device’s processing ability is
currently used. When this percentage is close to 100%, the Device is
running at full load, and the throughput is not going to improve
anymore. If you want some applications to have more throughput, you
should turn off other applications (for example, using QoS; see
Chapter
16 on page 189
).
Memory
Usage
This field displays what percentage of the Device’s memory is currently
used. Usually, this percentage should not increase much. If memory
usage does get close to 100%, the Device is probably becoming
unstable, and you should restart the device. See
Section 25.4 on page
264
, or turn off the device (unplug the power) for a few seconds.
Interface Status
Interface
This column displays each interface the Device has.
Status
This field indicates whether or not the Device is using the interface.
For the DSL interface, this field displays
LinkDown
(line is down) or
Up
(line is up or connected).
For the LAN interface, this field displays
Up
when the Device is using
the interface and
NoLink
when the line is disconnected.
For the WLAN interface, it displays
Up
when WLAN is enabled or
Disabled
when WLAN is not active.

connection on the Device) indicates a PPP connection via any one of the
WAN interface.
The number after the dot (
.
) represents the VLAN ID number assigned to
traffic sent through this connection. The number after the underscore
(
_

interface.
(null)
means the entry is not valid.
Description
This shows the descriptive name of this connection.
0
and
35
or
0
and
1
are the default VPI and VCI numbers. The last
number represents the index number of connections over the same PVC
or the VLAN ID number assigned to traffic sent through this connection.
(null)
means the entry is not valid.
Received
Bytes
This indicates the number of bytes received on this interface.

Route Info
Routing is based on the destination address only and the Device takes the shortest
path to forward a packet. Click
Status > Route Info
to access this screen. Use
this screen to view the internal routing table on the Device.

DESCRIPTION
Destination
This indicates the destination IP address of this route.
Gateway
This indicates the IP address of the gateway that helps forward this route’s
traffic.
Subnet
Mask
This indicates the destination subnet mask of this route.
Flag
This indicates the route status.
U
p: The route is up.
!
(Reject): The route is blocked and will force a route lookup to fail.
G
ateway: The route uses a gateway to forward traffic.
H
ost: The target of the route is a host.
R
einstate: The route is reinstated for dynamic routing.
D
ynamic (redirect): The route is dynamically installed by a routing daemon
or redirect
M
odified (redirect): The route is modified from a routing daemon or
redirect.
Metric
The metric represents the "cost of transmission". A router determines the
best route for transmission by choosing a path with the lowest "cost". The
smaller the number, the lower the "cost".
