What is the difference between the two access modes, Ad hoc mode and Infrastructure mode?

Ad hoc mode
Access mode of the wireless LAN which does not use an access point and allows direct communication of the network devices.
Infrastructure mode
Access mode of the wireless LAN in which the network devices communicate with each other via an access point. By connecting the access point to a wired LAN environment, it allows the communication among devices connected to a wireless and wired LAN. This mode is used in the general wireless LAN environment.

Is there any information I should check before configuring wiDock?

To connect wiDock in Infrastructure mode, please check the following configuration information of the access point.

SSID (ESSID)	ID to identify the access point.
Encryption requirements	Whether encrypted communication with the access point is required or not.
Encryption mode	Encryption type (WEP, WPA, WPA2 and etc.) in case it is required.
Encryption key	Key necessary for encryption. WEP key, when using WEP encryption. Pre-Shared Key, when using WPA/WPA2 encryption.
Key index	Which key from 1 to 4 is enabled, when using a WEP key.
Other security function	Information for a security function configured to an access point. e.g. MAC address filter if a security function is configured to the access point, configuration of the access point needs to be changed to allow the communication with wiDock.

Please refer to "Prepare Configuration Information for a Wireless LAN" - "How to find SSID" if you do not know SSID.

Does wiDock support the auto-connection function of the access point?

wiDock does not support proprietary auto-connection function of the access point implemented by each manufacturer.
If the environment setting of an access point has been set using the auto-connection function of the access point, please check the configuration information listed in the previous section. If there is any unclear information, configuration of the access point needs to be changed manually.

How should I determine the way to assign an IP address to wiDock?

There are two ways to assign an IP address to wiDock; one is to Get IP address automatically from DHCP server and the other is to Assign IP address manually. Choose the way to assign an IP address according to your environment.

When there is a DHCP server in the network environment
Solution	You can use Get IP address automatically from DHCP server. As wiDock is set by default to Get IP address automatically, wiDock will obtain an IP address appropriate to your network environment from the DHCP server just by powering up wiDock. Please refer to "Reset to Factory Default" for the procedure to reset wiDock to the factory default settings.

Solution

Please Assign IP address manually. Keep in mind of the following points regarding the IP address to assign to wiDock.

Assign an IP address unique in the network.
Assign an IP address that has the same address class as the PC that will use wiDock.
e.g. When an IP address of the PC is “192.168.0.xx”, assign an address such as “192.168.0.100” that is not used by other network devices.

(Tips about the IP address)

An IP address is a unique number for identifying network devices. An IP address is indicated with four numbers divided by a period (.), for example “192.168.0.1”. The integer from 0-255 is used for each number.
An IP address is, depending on the number assigned, categorized to 3 classes below.
Numbers making up the IP address are either network numbers indicating network, or host numbers indicating each network device; each number indicates the different meaning based on the IP address class. Each class is categorized as the following diagram which is indicating a network number as n, and a host number as u. An IP address with the same network number must be assigned to the network devices in the same network segment.

There is an address range in the IP address called the private address that could be used freely. In the LAN environment not directly connected to the internet, an IP address is assigned within the range of the private address.

First 1 digits in IP address	Class	Definition of IP address n: network number u: host number	Size of the network to be used	Private address
0 - 127	A	n.u.u.u	Large network	10.0.0.0 - 10.255.255.255
128 - 191	B	n.n.u.u	Mid-size network	172.16.0.0 - 172.31.255.255
192 - 223	C	n.n.n.u	Small network	192.168.0.0 - 192.168.255.255
