Section 7 - Frequently Asked Questions
After the PC-on-TV device application closed, my laptop wireless utility stopped working.
If a third-party wireless configuration utility is in control, refer to its user’s guide to set it to proper operation.
However, if your computer uses the Windows
®
wireless utility, note the following:
• The PC-on-TV device application controls the computer’s wireless device with standard Windows
®
APIs.
• The application disables the Wireless Zero Configuration (WZC) to ensure Windows
®
does not override any
attempt to connect with a PC-on-TV device.
• WZC is an application supplied by Microsoft with the Windows
®
XP platform to scan and associate with
desired access points.
• Upon exiting, the PC-on-TV device application restores the WZC configuration. Typically, WZC starts automatically.
If it does not, follow these steps to enable Microsoft WZC manually, Select: Start, Control Panel, Administrative
Tools, Services, Wireless Zero Configuration, and select Start the Service.
How can I resolve wireless performance issues in a crowded WLAN environment?
To resolve performance issues, try changing the channel. (You can change the channel in the PC-on-TV device
application under Device Settings, Network Settings.)
In crowded WLAN environments, collisions with other APs and clients (stations) and the resultant need for packet
retransmissions can result in lower effective throughput between the computer and the PC-on-TV device.
2.4GHz WLAN has several available channels. In many cases, changing to a different channel can reduce congestion
and improve throughput, improving performance significantly.
Are there configuration parameters to be set for the Audio area?
