Re: Wiressless N dongle Issue
This comes from Iboum.com
Wireless networking is generally not reliable enough for streaming HD video, therefore it is not recommended for Media Players. We are not saying that it won't work, just that you may encounter stuttering / lag problems. Of course, using Wi-Fi to copy files across a network will work fine. For this reason most Media Players omit Wi-Fi from their specifications and instead offer optional support via a USB dongle.
The maximum data transfer rate for Wi-Fi(g) is 54 Mbit/s with actual achievable rates usually being less than half of this. Wi-Fi(n) can achieve higher data transfer rates of up to 300 Mbit/s but, again, actual rates will be lower.
