Good WLAN stick and work on Samsung BUT

Have bought the stick because of the good reviews. It also works perfectly with my Samsung 46C750 and comes to the Internet, etc. But despite Draft-N standard come no above-average transfer rates together. Streaming video on internal apps on the TV only works jerky ...

Streaming up to a resolution of 720p works ...
nor is a DTS audio track, one may forget the ...
Let alone 1080p, every 8 seconds, recharge the TV.

All sources of interference has been excluded, as the PC was connected with a cable. 2 concrete walls are between TV and router ... shame ... well ne hard drive to the TV and tuts ... so ... and seamless ...
But otherwise good stick, but as already mentioned very hot
