The TL-WPA281 is from a theoretical point of a perfect device. Unfortunately, he does not consider what the advertisements (the Prospectus, etc.) promises. The decor is simple if you know a bit about networks. But in practice, the device sucks but then enormous: registration in the WLAN is x times tries, but fails x times and the time goes by. But even worse is it when a PC or Tablet PC is finally registered in the tub, then has the 2nd unit or Mediabox or whatever, only more problems. Operating without WLAN super or 1 device on the wireless but unfortunately not both at the same time. Now I use instead of the TL-WPA281 again a normal AV200 Powerline Adapter with my "old" WiFi router and everything runs lightning speed and without interference> So it is up to TL-WPA281, shame.
