This is the second Linksys AE3000 I have purchased. I bought the first one 2 years ago and it's still working. We needed the second one to replace a different wireless adapter on a different computer.
Like the first time around, installation was easy. The CD doesn't install any bloatware or proprietary software. The CD helps to configure your wireless network connection. Assuming your wireless network is configured properly, installation and configuration takes about 3 minutes.
That's about it. It simply works.
