This was my third ethernet adapter in 2 years by different brands. They're clearly not built to last as each has lasted only a few months. I bought this one on July 8 based on more positive reviews, and as of August 24, it's already stopped working. It's been unstable over the past 2 weeks, and today it finally gave up. The blue light goes on and off but is no longer making a connection. My USB ports are fine as I've tried other devices with each of them. At $14 for 7 weeks of service, I'm paying $2/week and now need to get another one.
