■ I changed the Access Point’s operation mode or I switched to a
different Access Point, and I cannot establish the connection.
For Windows Me users, when your Access Point configuration is changed to a
different mode, make sure to update the IP address as follows:
1 From the “Start” menu, click “Run”.
2 Type “winipcfg” (without quotation marks), and click “OK”.
The IP Configuration dialog box appears.
3 Select “Sony Wireless PC Card” from the drop-down list, and click “Release”.

5 Wait until the new IP address is obtained.
■ In Peer-to-Peer mode, the signal strength is not displayed. How do I
tell whether a peer-to-peer connection has been successfully
established?
Because in Peer-to-Peer mode your computer can connect to multiple other
computers, each with its own signal strength, a signal strength cannot be
displayed.
To verify the connection in Peer-to-Peer mode, performe the following
procedures.
❑ Windows Me and Windows 2000
1 Double-click the My Network Places icon on the desktop.
2 Double-click “Computers Near Me”.
3 Press the F5 key to update.
4 Check whether your peers exist on your network.
❑ Windows XP
1 Access “My Network Places”.
2 Press the F5 key to update.
3 Check whether your peers exist on your network.
■ “Renewing IP address failed” message appears in Peer-to-Peer
mode (Windows 2000). What should I do?
“Renewing IP address failed” or “DHCP Server Unavailable: Renewing adapter”
message appears when the IP address is not obtained from the DHCP server.
If these messages appear, click “OK”. In Peer-to-Peer mode, Windows releases
the IP address, so performance is not affected.
