I have the Asus N53 for some time now in use and am very satisfied with the performance offered. As Access Point serves a Netgear N600. Stick and Access Point are approximately 7m apart and in between there is a 30 cm thick wall. Both the 2.4 GHz operation as well as in the 5 GHz operation, the connection is 100% stable. The connection rate that is displayed in Windows 7, but varies in both frequency ranges between 216 Mbit / s and 300 Mbit / s. Much more important than these values, however, the effective throughput. This I tested by I pushed a 2 GB file via the WLAN on my NAS or copied from there. Result: PC -> NAS: about 11.5 MB / s NAS -> PC: approx 13 MB / s The values are perfectly fine and move on a level with a 100 Mbit / s LAN. The values were achieved without any problems in the 5 GHz range in both the 2.4 GHz.
Furthermore, a positive note, the well-functioning drivers under Win 7 x64. The driver of the Fritz! WLAN sticks which I had in operation previously, I could no longer get through to the power saving mode. When Asus N53 that works fine. In addition, the drive is also recommended for the Linux community very. The current Ubuntu 04.12 has recognized the stick immediately and allows connections to 2.4 GHz and 5 GHz network.
