I bought the NETGEAR WNDA3100 a month and a half ago, which gave me plenty of time to test it out. The reason for purchase was the following: I had purchased a desktop PC, but unfortunately did not have the option to run an Ethernet cable from the router to my PC, which is located on a different floor.
In general, USB network adapters received better reviews than built-in wireless network cards, and the NETGEAR WNDA3100 USB adapter received better reviews than others. The relatively cheap price compared to similar peripherals also appealed to me. I was not familiar with the brand, but I did enjoy an image with an eye on quality.
Installation via the supplied CD was very easy. The option was also given to download the drivers online and finally there was the option to install only the driver (without driver programs). The driver program is user-friendly, but also unnecessary as the driver is more than sufficient.
In addition to the installation CD-ROM, manuals and the network adapter itself, a USB extension cable and a holder are also included. The latter two can be used to position the adapter more practically in order to obtain a better connection.
The final connection is stable and fast. The download speed is twice as fast compared to my laptop and it never cuts out (when my laptop often finds the internet in the same place as the PC is now). Note: I'm barely ~5m from the router, but the connection bridges a floor.
The main purpose is gaming and this works perfectly. So far I haven't had any network issues that I can attribute to the USB network adapter.
