TROUBLESHOOTING
There is a delay between the smart device and TV.
Wireless technology is radio-based, which means connectivity
and the throughput performance between devices decreases
when the distance between devices increases. Other factors
that will cause signal degradation (metal is generally the worst
culprit) are obstructions such as walls and metal appliances. As
a result, the typical indoor range of your wireless devices will be
between 10 to 50 feet. In order to determine if wireless issues are
related to range, we suggest temporarily moving the smart device,
if possible, to 5 to 10 feet away from Miracast Video Adapter. If
you find that range was the problem, try changing the frequency
band to the option that isn't selected and see if that resolves any
issues. You may also want to consider taking your smart device
off of your home Wi-Fi network while leaving the Wi-Fi radio on.
Please also ensure that both the Miracast Video Adapter's firmware
and your smart device's software are up to date with the latest version.
