NOTE:
Unlike the push-button method, the pin method has no set time limit.
This means that the router will continue searching until it finds a client.
Step 6:
Select the PIN radio button in the WSC Setup section of the Wireless
Security screen, as shown in
A
or
B
below, and then click the appropriate
button based on the WSC AP mode selected in step 2.
A -
For
Configured
mode, enter the client PIN in the box provided and
then click the
Add Enrollee
button (see below).
B
- For
Unconfigured
mode, click the
Config AP
button.
Step 7:
Activate the PIN function on the wireless client.
For
Configured
mode,
the client must be configured as an Enrollee.
For
Unconfigured
mode,
the client must be configured as the Registrar.
This is different from the
External Registrar function provided in Windows Vista.
The figure below provides an example of a WPS client PIN function in-progress.
Now go to Step 8 (part IV. Check Connection) to check the WPS connection.
IV. CHECK CONNECTION
Step 8:
If the WPS setup method was successful, you will be able access the
wireless AP from the client.
The client software should show the status.
The example below shows that the connection established successfully.
You can also double-click the Wireless Network Connection icon from the
Network Connections window (or the system tray) to confirm the status of
the new connection.

MAC Filter
This option allows access to the router to be restricted based upon MAC addresses.
To add a MAC Address filter, click the
Add
button shown below.
To delete a filter,
select it from the MAC Address table below and click the
Remove
button.
Option
Description
Select
SSID
Select the wireless network name from the drop-down box.
SSID
stands for Service Set Identifier.
All stations must be configured with
the correct SSID to access the WLAN.
If the SSID does not match, that
user will not be granted access.
MAC
Restrict
Mode
Disabled: MAC filtering is disabled.
Allow: Permits access
for the specified MAC addresses.
Deny: Rejects access for the specified MAC addresses.
MAC
Address
Lists the MAC addresses subject to the MAC Restrict Mode.
A maximum
of 60 MAC addresses can be added.
Every network device has a unique
48-bit MAC address.
This is usually shown as xx.xx.xx.xx.xx.xx, where
xx are hexadecimal numbers.
After clicking the
Add
button, the following screen appears.
Enter the MAC address in the box provided and click
Save/Apply
.

Wireless Bridge
This screen allows for the configuration of wireless bridge features of the WLAN
interface.
See the table beneath for detailed explanations of the various options.
Click
Save/Apply
to implement new configuration settings.
Feature
Description
AP Mode
Selecting
Wireless Bridge
(aka Wireless Distribution System)
disables Access Point (AP) functionality, while selecting
Access
Point
enables AP functionality.
In
Access Point
mode,
wireless bridge functionality will still be available and wireless
stations will be able to associate to the AP.

Feature
Description
Bridge Restrict
Selecting
Disabled
disables wireless bridge restriction, which
means that any wireless bridge will be granted access.
Selecting
Enabled
or
Enabled (Scan)
enables wireless bridge
restriction.
Only those bridges selected in the Remote Bridges
list will be granted access.
Click
Refresh
to update the station
list when Bridge Restrict is enabled.

Advanced
The Advanced screen allows you to configure advanced features of the wireless LAN
interface. You can select a particular channel on which to operate, force the
transmission rate to a particular speed, set the fragmentation threshold, set the RTS
threshold, set the wakeup interval for clients in power-save mode, set the beacon
interval for the access point, set XPress mode and set whether short or long
preambles are used.
Click
Save/Apply
to set new advanced wireless options.
Field
Description
Band
Set to 2.4 GHz for compatibility with IEEE 802.11x standards.
The new amendment allows IEEE 802.11n units to fall back to
slower speeds so that legacy IEEE 802.11x devices can coexist
in the same network. IEEE 802.11g creates data-rate parity at
2.4 GHz with the IEEE 802.11a standard, which has a 54 Mbps
rate at 5 GHz. (IEEE 802.11a has other differences compared
to IEEE 802.11b or g, such as offering more channels.)
Channel
Drop-down menu that allows selection of a specific channel.

802.11n/EWC
An equipment interoperability standard setting based on IEEE
802.11n Draft 2.0 and Enhanced Wireless Consortium (EWC)
Bandwidth
Select 20GHz or 40GHz bandwidth.
40GHz bandwidth uses
two adjacent 20GHz bands for increased data throughput.
Control Sideband
Select Upper or Lower sideband when in 40GHz mode.
802.11n Rate
Set the physical transmission rate (PHY).
802.11n
Protection
Turn Off for maximized throughput.
Turn On for greater security.
Support 802.11n
Client Only
Turn Off to allow 802.11b/g clients access to the router.
Turn On to prohibit 802.11b/g clients access to the router.
54g Rate
Drop-down menu that specifies the following fixed rates:
Auto: Default.
Uses the 11 Mbps data rate when possible but
drops to lower rates when necessary.
1 Mbps, 2Mbps,
5.5Mbps, or 11Mbps fixed rates.
The appropriate setting is
dependent on signal strength.
Multicast Rate
Setting for multicast packet transmit rate (1-54 Mbps)
Basic Rate
Setting basic transmission rate.
Fragmentation
Threshold
A threshold, specified in bytes, that determines whether
packets will be fragmented and at what size.
On an 802.11
WLAN, packets that exceed the fragmentation threshold are
fragmented, i.e., split into, smaller units suitable for the circuit
size.
Packets smaller than the specified fragmentation
threshold value are not fragmented.
Enter a value between
256 and 2346. If you experience a high packet error rate, try to
slightly increase your Fragmentation Threshold.
The value
should remain at its default setting of 2346.
Setting the
Fragmentation Threshold too low may result in poor
performance.
RTS Threshold
Request to Send, when set in bytes, specifies the packet size
beyond which the WLAN Card invokes its RTS/CTS mechanism.
Packets that exceed the specified RTS threshold trigger the
RTS/CTS mechanism.
The NIC transmits smaller packet
without using RTS/CTS.
The default setting of 2347
(maximum length) disables RTS Threshold.
DTIM Interval
Delivery Traffic Indication Message (DTIM) is also known as
Beacon Rate.
The entry range is a value between 1 and
65535. A DTIM is a countdown variable that informs clients of
the next window for listening to broadcast and multicast
messages.
When the AP has buffered broadcast or multicast
messages for associated clients, it sends the next DTIM with a
DTIM Interval value.
AP Clients hear the beacons and awaken
to receive the broadcast and multicast messages.
The default
is 1.
