Hoc Mode and the proper SSID to form the 802.11 Ad Hoc Network. Install and enable the
ICS (Internet Sharing Software, such as "SyGate"...) function in your host computer. (Note
that the Windows 2K or later version, OS, supports the ICS function in Local Area
Connection Properties→ Sharing)
(3) Set your Pocket PC as 802.11 Ad Hoc Mode and choose the same SSID to join the 802.11
Ad Hoc Network (choose the DHCP to get the IP assigned).
(4) Check and make sure the Wireless LAN Adapter in the 802.11 Ad Hoc Network have the
same IP group. (Please Ping each other to make sure the connection is successful)
(5) Now you can access the LAN resource successfully.
B7: What should I do if my host computer cannot wirelessly connect with my Pocket PC?
(1) Make sure you have setup the partnership for your Pocket PC and your host computer.
(2) Make sure you are within the range of a working network.
(3) Make sure you have entered the IP address of the host computer as the WINS server on
your Pocket PC.
(4) Reset your Handheld PC or Pocket PC to make the TCP/IP settings take effect

C. Application
C1. What should I do to use the ActiveSync Function through Wireless Network?
(1) Make sure you have already setup the partnership for your Pocket PC and your host
computer through USB Interface and the ActiveSync can work properly. (The ActiveSync
connection Interface should also choose the Ethernet interface for Wireless LAN
ActiveSync Connection)
(2) Make sure you are within the range of a working Wireless Network.
23
(3) Make sure you can Ping your Pocket PC from your Host Computer. (Make sure the SSID,
WEP keys and channel for all devices in the network are set the same.)
(4) Make sure you have entered the IP address of the host computer as the WINS server on your
Pocket PC.
(5) Reset your Pocket PC to make the TCP/IP settings take effect and execute the ActiveSync
function in the Pocket PC to enjoy the high speed ActiveSync Wirelessly.
C2. How do I wirelessly browse the Internet?
(1) If your network uses DHCP (Dynamic Host Configuration Protocol), an IP address and
DNS (or WINS) will be assigned automatically. On your Pocket PC, simply click Start→
Setting→Connections→Network Adapters→IEEE802.11b WLAN Adapter→Properties to
set the proper setting for Internet connection.
(2) If your network does not use DHCP, you should enter the IP address, subnet mask, gateway
and DNS (or WINS).
IP Address is Internet Protocol Address; a numeric address such as 10.37.238.100 that the
domain name server translates into a domain name. Each node on the IP network should
have a unique IP address.
Subnet mask is a number used to identify a subnetwork when multiple networks share one
IP address. For example 255.255.255.0Gateway is a device used to forward IP packets to
and from a remote destination.
DNS stands for Domain Name System, a database system, which translates addresses and
domain names. For example, a numeric address like 232.245.021.54 can become something
like cba.com.
WINS stands for Windows Internet Naming Service which has two functions; one is a
Microsoft Net BIO name server that eliminates the broadcasts needed to resolve computer
names to IP addresses by providing a cache or database of translations. The other one is to
set the IP address of the host computer that you already construct the partnership for
Network adapter Active sync purpose.
To set IP address, Subnet mask and Gateway, click Start→Settings→Connections→
Network Adapters→IEEE802.11b WLAN Adapter→Properties→IP Address.
To set DNS or WINS (Windows Internet Naming Service), click Start→Settings→
Connections→Network Adapters→IEEE802.11b WLAN Adapter→ Properties→Name
Servers.
(3) To ping your Pocket PC from your host computer. In the Host Computer, open the DOS
command mode window, type the command "Ping" followed by the IP address, such as
"Ping 140.124.40.112". If you can see the reply from this IP address, the connection is
complete. You are now ready to browse the Internet using Internet Explorer on your Pocket
PC.
C3. How do I wirelessly check my e-mail?
(1) Please make sure that you can use the ActiveSync function through USB Interface at first,
24
and make sure you can use the ActiveSync to receive and send e-mail successfully. For
corporate e-mail received and sent, please check with your network administrator for
necessary connection settings.
(2) Make sure you have entered the IP address of the host computer as the WINS server on your
Pocket PC.
(3) Reset your Pocket PC to make the TCP/IP settings take effect and execute the ActiveSync
function in Pocket PC to enjoy the high speed ActiveSync Wirelessly to receive and send email.
D. Settings
D1. What is SSID? What should I set in the SSID field?
SSID stands for Service Set Identification, which is the ID to form the Wireless Network. You
can set up to 32 characters in the SSID field. For the Infrastructure Mode, you should set the
SSID the same as the Access Point been connected with. To create a 802.11 Ad Hoc Network,
the SSID must be the same among stations to enable the wireless communication within the
local area network.
Note!
You need to choose a proper SSID and channel for the first 802.11 Ad Hoc station. For other
stations want to join the same SSID group, you could only choose the same SSID as the first
station, but the channel will not take effect. The 802.11 Ad Hoc must enter the proper SSID.
Blank SSID for the 802.11 Ad Hoc Mode is not allowed. The stations want to join the 802.11
Ad Hoc Network must have the same SSID and are suggested to have the same IP Address in
the Network group.
D2. Why can't I choose the "Channel" and "Country" field in "Infrastructure" Mode?
For the Infrastructure Mode, the Country and Channel are decided by the Access Point. You can
only join the existing Access Point formed Wireless Network but not create a new Wireless
Network. That is the reason why you can't set the "Channel" and "Country" settings.
D3. When should I set the IP address, Subnet mask and Default gateway settings?
When the Wireless Network does not have the DHCP server, you should set your own IP
address, Submask and Default gateway for Wireless Network connection. Otherwise, the OS
might set the different Network group IP address for you, which will cause the disconnection
for the Wireless Network.
D4. How can I set the IP address, Subnet mask and Default gateway settings?
Simply click Start→Settings→Connections→Network adapter→IEEE802.11b WLAN Adapter
→Properties→IP Address to set IP address, Subnet mask and Default gateway settings.
25
D5: What Transmit Rate should I choose for Wireless Connection?
Suggest you to use the "Fully Auto" option in the "Transmission Rate" field for full
Transmission Data Rate range to automatically adjust the Best Communication Data Rate and
to be compatible with other Low speed 802.11 Wireless Device.
E. Security
E1: What is WEP?
WEP stands for Wired Equivalent Privacy, a security service, used to prevent the unauthorized
access to your wireless network.
E2: How many WEP security service modes does my Wireless LAN support?
WEP stands for Wired Equivalent Privacy that is the security service for the Wireless Network.
There are three WEP security service modes available for "IEEE 802.11b WLAN Adapter"
formed Wireless Network. The first is "Disable" which will disable the WEP security service;
the second is "64bit" which will support 5 bytes Hexadecimal value WEP security service; the
third is "128bit" which will support 13 bytes Hexadecimal value WEP security service.
E3: How do I set the WEP security service?
Please click Start→Settings→System→Wireless LAN Utility→Advanced to view Advanced
page where you can set the WEP security service. Please choose the proper WEP Key Mode,
WEP KeyID and WEP Key value for the Wireless Network.
Note!
The WEP Mode, WEP KeyID and WEP Key value must be exactly the same as your Wireless
Network's to enable the connection.
Example of setting the WEP:
You can choose
1.
WEP Mode "64bit", KeyID "1" and Key "1234567890", or
2.
WEP Mode "128bit", KeyID "1" and Key "12345678901234567890123456", or
3.
WEP Mode "Disable" for connection
F. Performance
F1: Will IEEE802.11b WLAN Adapter work in the environment where Bluetooth network is
employed?
Yes, IEEE802.11b WLAN Adapter can coexist with Bluetooth environment.
F2: How far is the working range of IEEE802.11b WLAN Adapter?
It depends on the data transmission rate and the condition of the environments. The higher the
data rate, the smaller the range it could cover. At 11 Mbps, the adapter can go up to 300 meter
in an outdoor environment; however, in an indoor environment, it can only go up to 100 meter.
26
Because of the ceilings, higher RF interference, interior walls and reflected signals, indoor
range is usually shorter than outdoor range.
F3: How does the data transmission rate work?
IEEE802.11b WLAN Adapter allows you to choose one of the six data rate options: Fixed
1Mbps, Fixed 2Mbps, Fixed 5.5Mbps, Fixed 11 Mbps, Auto Select 1 or 2 Mbps, and Fully Auto.
The farther the distance between two communicating devices, the slower the data rate should be
used. Basically, with slower data rate, the data delivery will be more reliable. If you don't know
which data rate should be used, simply choose "Fully Auto", and the data rate will
automatically step down from 11 Mbps, 5.5 Mbps, 2 Mbps, to 1 Mbps if you move farther your
Pocket PC away from the Access Point or other connected mobile device.
F4: The Wireless LAN uses lots of power. What should I do to save power?
(1) Please turn off the WirelessLAN Switch if you are not using the Wireless Network currently,
or
(2) You can click the "Radio Off" button on Start→Settings→System→Wireless LAN Utility→
Config page to temperately disable the RF function , or
(3) You can click Start→Settings→System→Wireless LAN Utility→Advanced to get into
Advanced Page and tick the "Enable Power Saving Mode" to enter the Power Saving Mode.
Note!
(1) Turn off the WirelessLAN Switch will cause the disconnection of the Wireless Network,
please make sure to close all the Wireless Connection before you execute this function.
(2) "Radio Off" function will cause the disconnection of the Wireless Network , please make
sure to close all the Wireless Connection before you execute this function.
(3) Enable "Power Saving Mode" will keep the connectivity but will lower down the average
throughput due to longer connection period for the Wireless Network.
(4) If you are in 802.11 Ad Hoc Mode, you are not allowed to enable "Power Saving Mode",
because Ad Hoc Mode doesn't support this function.
F5: How do I make sure that the Wireless LAN SW has been installed successfully and that
Wireless LAN already work properly?
(1) Please check if the "IEEE 802.11b WLAN Adapter" already exist in Start→Settings→
Connections→Network Adapters; if not , the Wireless LAN Driver is not Installed
successfully.
(2) Please check if the Wireless LAN Utility already exist and could be opened successfully by
simply click Start→Settings→System→Wireless LAN Utility.
(3) Click Start→Settings→System→Wireless LAN Utility→Link to check the current Link
information in the Link Page.
