TP-Link TL-WN821N / N300
The stick is ready for use after installing the included driver immediately. The WLAN connection is very stable, bringing with me a net throughput of about 50-90 Mb / s, depending on your connection quality.
For Internet connections to 50Mb clearly recommended / s.
More currently, anyway not really make sense, because the servers on the Internet are mostly represent the bottleneck.
TP-Link TL-WDN3200 N600
Good stick, he shaft a transfer rate of 90MB / s to 98MB / s in the 5 GHz WLAN my Fritzbox 7390th
But beware, it does not support all the radio channels of the 5GHz frequency band, this should will therefore fixed.
Addendum: At the Fritz box 7490, these stem stick the full 100Mb / s of my cable Germany Internet line.
