There is no single command that provides thisinformation; however, the administrator can determine it in two ways:1. If the wireless handset IP address is statically configured, theadministrator can look at the IP address of the wireless handset usingthe Admin menu, which is available when the wireless handset ispowered on.2. After the wireless handset is operating and in standby mode, theadministrator can look at the User Preferences menu to find the alias IPaddress of the wireless handset.For more information, see WLAN Handsets Fundamentals (NN43001-505).Troubleshooting coverage issuesCoverage issues are best resolved by adding and relocating APs asrequired.
