Wireless WAN

What should I do if my computer cannot connect to the wireless WAN?

❑ Make sure the battery pack is installed properly and charged.

❑ Activate a mobile broadband service account with a supported carrier.

❑ Have adequate mobile coverage in your area. Check with your network provider for additional coverage information for

your location.

❑ Make sure the WIRELESS switch is on and the WIRELESS indicator light is lit on your computer.

❑ Make sure the switch next to Wireless WAN is set to On in the VAIO Smart Network window.

❑ Check that your connection manager software has detected the wireless WAN modem successfully. It may take some

time for the software to detect the wireless WAN modem.

❑ Make sure the SIM card holder is properly inserted into the SIM card slot.

❑ If you have disabled the wireless devices in the BIOS setup screen, you cannot access the Internet through a wireless

network. To enable the devices, follow the steps in Disabling Built-in Devices (page 143).
