GC89 WLAN Information

You can view detailed technical information about your GC89 WLAN connection by selecting the Information tab in the Sony Ericsson Wireless Configuration Utility. Your MAC number is listed on this screen.

Concurrent WLAN and GPRS

The GC89 supports concurrent connections to GPRS and WLAN, however this ability may have been disabled for security reasons.

Switching between GPRS and WLAN connection is not automatic, even if both are available or the WLAN connection is established automatically as you enter the hotspot. This is because the connections will have different IP numbers. You are advised to check your connections as you enter and leave hotspots. You may need to re-request a transaction (for example refresh a web page) or restart an application.
