Changing the default wireless settings on your router
1.
Connect wirelessly or via the Ethernet port of a computer to configure wireless operation. Start your web
browser. Enter the default address http://192.168.1.1. User name and password are both
admin
.
2.
Go to
Wireless > Basic
. By default the SSID is set to ‘wireless’, however you can use any SSID of your
choice. Pick a desired channel, the default channel is 6. If there are other access points nearby, try to
choose a channel that is not in use to avoid interference. Wireless clients will scan all channels and use
the same channel as the access point. Click
Apply
.
3.
Set up wireless clients according to the section above. The router is also a wireless access point. Select
infrastructure mode
. Do not use Adhoc (or peer-to-peer) mode. Every wireless client should use the same
SSID and security as the access point.
Keep in mind that the default 64 bit WEP key is: a1b2c3d4e5
.
Increasing wireless security
Several options are available to increase your level of wireless security including:-
Hide SSID
– SSID is a name that identifies the network and this is periodically broadcast by the router to
signify it’s presence.
If you hide the SSID then it will not be broadcast and other wireless clients normally will
not see the router.
Change protection type
– 64-bit WEP is a minimum level of wireless security.
Advanced security is provided
by WPA/WPA2 and 802.1x.
Whichever protection method is selected in the router must also be used by
wireless clients wishing to connect.
Access control
– the MAC addresses of permitted clients can be registered in the router.
For detailed procedures, refer to page 100 of the User’s Guide.

SECTION 5
TIPS FOR SECURITY
This router is shipped secured by a firewall by default. In order to take full benefit from the security features of
this router:
Do:
•
Change your router’s administrative user name & password.
•
Back up your router’s configuration. See the router’s
Management > Backup Config
menu.
•
Disable UPnP if you don’t need this function.
•
Read about advanced functions of this router. Found in Chapter 4 of the User’s Guide on this CD.
Don’t:
•
Enable any form of remote access to the router unless you are confident in handling the security
implications. Remote administration of the router opens up the opportunity to breach the security of your
router and network. Use the built in access control list to restrict access to only authorised Internet hosts.
•
Enable IP extension (bridging) without firewall protection.
•
Send your router away for repair or replacement without resetting to factory default or wiping out
your Internet account login details. Use the Backup Configuration option to save your router’s settings
elsewhere. When a replacement unit is received, restore the original setting from the backup file.
SECTION 6
SOME ADVANCED FUNCTIONS
OF YOUR ROUTER
Firewall, port forwarding, DMZ & traffic restrictions
By default a firewall is actively blocking incoming requests from the Internet to your private network. In the
reverse direction requests sent from your network can freely pass through to the Internet.
If you have local servers on your network and want the servers accessible to Internet users, set up Virtual
Servers. Refer to Chapter 4 – Virtual Servers Port Forwarding on page 80 of the User’s Guide.
If you run applications that require unrestricted 2-way traffic between a computer on your network and the
Internet, set up the computer as DMZ Host. Refer to Chapter 4 – Virtual Servers DMZ Host on page 85 of the
User’s Guide. Caution – DMZ hosts are no longer protected by the firewall.
You can prevent or restrict access of selected computers to the Internet by defining IP Filters. Refer to
Chapter 4 – Firewall IP Filtering on page 89 of the User’s Guide.
Quality of Service (QoS)
The router allows prioritising of upstream traffic (to the Internet). The user specifies the traffic conditions and
traffic rules. The router has three queues for traffic priority: high, medium and low. Low priority packets are
not sent when there are higher priority queues.
To use QoS, refer to Chapter 4 – Quality of Service on page 92 of the User’s Guide.
Please refer to the User’s Guide for other advanced functions. Always restart the router to activate any changes to configuration.

TROUBLESHOOTING
The installation procedure in this Quick Start Guide assumes you are connecting the router via Ethernet
(recommended). If you are connecting the router via USB (not recommended), skip this section and refer to
Chapter 2 - USB Driver Installation
on page 21 of the User’s Guide on CD.
Preparation: Configure Computer to get IP Address
If your computer is already configured to obtain an IP address automatically (from a DHCP server), do nothing
(Windows default network setting). By default the router is a DHCP server and will assign an IP address to the
computer automatically.
If you are unsure of your computer’s network setting, refer to Chapter 2 of the User’s Guide. Pages 26-32
contain information on
Setting TCP/IP
for different versions of Windows.
Now go to
Section 3 – Getting On-Line
.
Q1. Cannot open the router control panel from my browser.
1.
Check that the ETHERNET light (1, 2, 3 or 4 if using the NB6Plus4 or NB6Plus4W) indicating the
connection to the computer is on. If not, check that the ETHERNET cable is firmly plugged in.
2.
Perform a PING test. In Windows Vista, click Start and type ‘cmd’ in the text bar and press Enter. In
Windows XP or 2000, click Start-Run. Enter cmd then OK. (In pre-2000 Windows versions enter
command instead). Type ping 192.168.1.1 then press Enter. The response should resemble:
Pinging 1±².168.1.1 with 3² bytes of data:
Reply from 1±².168.1.1: bytes=3² time=4ms TTL=30
….
If there is a similar response, the router is communicating with your computer correctly and the problem
lies elsewhere. If the result is Request timed out or similar failures, there may be a network problem.
Check that the ETHERNET cable is firmly plugged in.
3.
Disable any personal firewall or virus checker temporarily. If you are using Internet Explorer, go to Tools–
Internet options-Security. Reset security level of all 4 icons to default. You can revert to your customised
settings after configuring the router.
4.
If previously the computer had a dialup modem, check browser setting. For example in Internet Explorer,
go to Tools–Internet options–Connections, and select Never dial a connection. Also check LAN Settings
that the option Use a Proxy Server is not selected.
5.
If the router is connected to a network hub, try connecting the router directly to the computer in a
standalone setup to eliminate any possible problem associated with the hub.
6.
The router’s default IP address is 192.168.1.1. To access the browser control panel your computer must
be on the same subnet as the router. See also Q3.
Q2. Cannot connect to Internet or cannot browse
1.
Check that the ADSL light is on. Normally it takes less than one minute to establish an ADSL link, and the
light comes on. If the ADSL light does not come on, the router is not seeing any signal. Check that:
•
ADSL service has been enabled.
•
If there is a designated ADSL jackpoint for the service, make sure the router is connected directly
into this jackpoint. Other jackpoints cannot be used.
•
If there is no designated ADSL jackpoint, any jackpoints may be used. Connect the router directly into
a jackpoint, or through the port marked MODEM on a filter.
2.
If the ADSL light is on, but the PPP light is off, check that:
