Who uses wireless?
Wireless technology has become so popular in recent years that almost everyone is using it, whether it’s for home, office, business, we have a wireless solution for it.

•
Gives everyone at home broadband access.
•
Surf the web, check email, instant message, etc…
•
Gets rid of the cables around the house.
•
Simple and easy to use.
Small Office and Home Office
•
Stay on top of everything at home as you would at office.
•
Remotely access your office network from home.
•
Share Internet connection and printer with multiple computers.
•
No need to dedicate office space.
Where is wireless used?
Wireless technology is expanding everywhere not just at home or office. People like the freedom of mobility and it’s becoming so popular that more and more public facilities
now provide wireless access to attract people. The wireless connection in public places is usually called “hotspots”.
Using a Wireless Cardbus Adapter with your laptop, you can access the hotspot to connect to Internet from remote locations like: Airports, Hotels, Coffee Shops, Libraries,
Restaurants, and Convention Centers.
Wireless network is easy to setup, but if you’re installing it for the first time it could be quite a task not knowing where to start. That’s why we’ve put together a few setup steps
and tips to help you through the process of setting up a wireless network.
Tips
Here are a few things to keep in mind, when you install a wireless network.
Centralize your router or Access Point
Make sure you place the router/access point in a centralized location within your network for the best performance. Try to place the router/access point as high as possible in
the room, so the signal gets dispersed throughout your home. If you have a two-story home, you may need a repeater to boost the signal to extend the range.

Eliminate Interference
Place home appliances such as cordless telephones, microwaves, and televisions as far away as possible from the router/access point. This would significantly reduce any
interference that the appliances might cause since they operate on same frequency.
Security
Don’t let your next-door neighbors or intruders connect to your wireless network. Secure your wireless network by turning on the WPA or WEP security feature on the router.
Refer to product manual for detail information on how to set it up.
Wireless Modes
There are basically two modes of networking:
•
Infrastructure
– All wireless clients will connect to an access point or wireless router.
•
Ad-Hoc
– Directly connecting to another computer, for peer-to-peer communication, using wireless network adapters on each computer, such as two or more wireless
network Cardbus adapters.
An Infrastructure network contains an Access Point or wireless router. All the wireless devices, or clients, will connect to the wireless router or access point.
An Ad-Hoc network contains only clients, such as laptops with wireless Cardbus adapters. All the adapters must be in Ad-Hoc mode to communicate.
Wireless Security
This section will show you the different levels of security you can use to protect your data from intruders. The router offers wireless security options like WPA/WPA2
PSK/EAP.
What is WPA?
WPA (Wi-Fi Protected Access) is a Wi-Fi standard that was designed to improve the security features of WEP (Wired Equivalent Privacy).
The 2 major improvements over WEP:
•
Improved data encryption through the Temporal Key Integrity Protocol (TKIP). TKIP scrambles the keys using a hashing algorithm and, by adding an integrity-
checking feature, ensures that the keys haven’t been tampered with. WPA2 is based on 802.11i and uses Advanced Encryption Standard (AES) instead of TKIP.
•
User authentication, which is generally missing in WEP, through the extensible authentication protocol (EAP). WEP regulates access to a wireless network based on
a computer’s hardware-specific MAC address, which is relatively simple to be sniffed out and stolen. EAP is built on a more secure public-key encryption system to
ensure that only authorized network users can access the network.
WPA-PSK/WPA2-PSK uses a passphrase or key to authenticate your wireless connection. The key is an alpha-numeric password between 8 and 63 characters long. The
password can include symbols (!?*&_) and spaces. This key must be the exact same key entered on your wireless router or access point.

Frequently Asked Questions
What can I do if my Router is not working correctly?
There are a few quick steps you can take to try and resolve any issues:
•
Check that all the cables are firmly connected at both ends.
•
Check that all the corresponding LED indicators are on, especially the Power, DSL, and LAN LED indicators.
•
Ensure that the settings on the WAN Service page in the Web User Interface are the same as the settings that have been provided to you by your ISP.
Why can’t I get an Internet connection?
For ADSL ISP users, please contact your ISP to make sure the service has been enabled/connected by your ISP and that your ISP username and password are correct.
What can I do if I forgot my web UI login password?
If you forgot your password, you must reset your router. Unfortunately this process will change all your settings back to the factory defaults.
To reset the router, locate the reset button (hole) on the rear panel of the unit. With the router powered on, use a paperclip to hold the button down for 10-15 seconds.
Release the button and the router will go through its reboot process. Wait about 30 seconds to access the router. The default IP address is
192.168.1.1
. When logging in, the
username is ‘
admin
’ and the password is ‘
admin’
.
How to set up other PVCs for IPTV and using IGMP?
1.
Contact your ISP to make sure that the IPTV service has been enabled/connected.
2. Go to
SETUP
->
INTERNET
, and click the
Manual Internet Connection Setup
button. Make sure the PVC settings, usually PVC2, the ATM settings, and Internet
Connection settings are correct. When a deactivated PVC setting is used, select the
Active
check box to enable the PVC.
3. Go to
ADVANCED
->
ADVANCED NETWORK
, and select the
Enable IPv4 Multicast Streams
check box to enable the IGMP service.
