Static IP Number Management
Some users may require a static IP number for the WLAN connection in the office and a dynamic IP
number outside the office.
If you are using Windows 98SE/Me/2000, it is necessary to manually change the TCP/IP properties
of the Sony Ericsson 802.11g Wireless LAN adaptor:

2. Right click the WLAN connection and select Properties General Internet Protocol
(TCP/IP) Properties.
3. Enter the static IP address for use in the office or select Obtain IP address automatically for
use outside.
Under Windows XP, this situation can be automated:

General Internet Protocol (TCP/IP) Properties.
2. In the General tab select Obtain IP address automatically.
3. In the Alternate Configuration tab select User configured and enter static IP address and any
other network parameters that are required.
