Why do WHQL certification messages appear during installation?
During the driver installation, you may see WHQL warning massages. The PC-on-TV device drivers have received
certification, but may be in the process of being re-certified for this latest version. Click Yes to these messages.
Will the PC-on-TV device work behind a firewall?
Windows
®
Firewall must be configured to allow the PC-on-TV device to access the Internet. If third-party firewalls are
installed (such as Zone Alarm), they can restrict access to the PC-on-TV device.
Either completely disable the firewall or configure it to allow FTP and HTTP traffic through to the device. Also make
sure it allows complete network access to/from the PC-on-TV device application.
What WiFi configuration is necessary to connect with the PC-on-TV device?
On the computer, check the WiFi configuration to ensure that the wireless radio is enabled and set to Infrastructure
mode.
Each PC-on-TV device must have a unique Name (SSID). Identical SSIDs on more than one unit will cause unpredictable
application behavior. The application may not connect to the desired PC-on-TV device if more that one has the same
Name (SSID).
Each PC-on-TV device is configured with a default Name (SSID) embedded in the firmware that cannot be changed.
However, through the PC-on-TV device application, a new Name (SSID) can be assigned to the device.
When the PC-on-TV device application is launched, it disables the Windows
®
Wireless Zero Configuration (WZC) utility
and uses Windows
®
NDISUIO to scan for Wireless PC-on-TV Devices. Some laptop wireless adapter vendors may
provide proprietary NDIS utilities and corporate IT departments may use third-party NDIS utilities that may interfere or
block Windows NDISUIO functionality.
When the application cannot locate APs through the NDISUIO API (NDIS User Mode I/O Application Programming
Interface), it generates a message to the user. The user needs to manually connect to the PC-on-TV device prior to
launching the application. Refer to your computer user guide for connection instructions for third-party wireless NDIS
module for configuration and management utility.
