Have ordered the TP-Link because simply fit value. Installation is simple, WPS button on the router, after that push WPS button on the TP-Link, 2min wait - done! But be careful with whom the Wi-Fi may not be possible goes, or only sometimes works. For me it was so that the four-protection program AVG has blocked the reception by the router. I wanted to return the TP-Link, but after an intensive search on the net I found the mistake. Have now on all devices (Samsung and Samsung S3 mini Tab3) the AVIRA it and everything works! So clear buy recommendation PS on the device itself, it is in the rarest cases! :-)
