The device offers a lot of advantages but does not work as I would imagine. I've always used the devices from TP-Link but this model to me now, however. Equipment example from D-LINK works perfectly - quick restart, N connectivity functions absolutely excellently
capably looked :) 1) Always outages 2) loss SSID after each short use 3) slow restart after setting 4) must play firmware in order to operate in the Czech Republic

Everything works without any problems, failures to register what other reviewers were not encountered.
Everything works as it should! Other people probably can not make it.

Complete satisfaction. 1) Quick Setup 2) Smooth operation was also purchased with the router USB 3g modem TP-LINT MA260 and also no problems with the setup and functionality. The only thing that was necessary beforehand to do was to upgrade the firmware to the latest version. Then, the menu settings mobile networks showed the possibility to enter the Czech operators. With the use of the card by Vadafone - almost 16Mbps download (obviously depending on network load) Maybe someone would be likely to confuse the English menu.
