Review on Netis WF2120 Wireless N150 Nano USB Dongle by Andre Pendergrass

I'm using this with a Mac Pro that has poor built-in Wi-Fi. This antenna definitely improves my reception. But it disconnects when the computer is sleeping and often reconnects very slowly. The instructions weren't clear, but the manufacturer answered, albeit not much more clearly. **January 2016 Update** With Mac OS El Capitan, my computer would not wake up from sleep, and after some testing, I settled on this antenna. I contacted tech support for a new driver and in the meantime I had to remember to unplug the antenna before I left the computer. Technical support is located in China, with very limited English. They didn't have any new software at the time, but they sent it to me as soon as the beta was available. I had to uninstall the previous version to install the beta version. The beta didn't work and I can't restore and run the old software and tech support just told me to google as they can't google in China. Now I have NO working WiFi and am very unhappy.
