Summary: Works great I can connect to wifi and bluetooth easily with my HP Envy m6 on Ubuntu Gnome Remix 14.04 and it was just plug and play no additional configuration needed awesome product it arrived one day after estimated which is awesome!
Summary: There are many Intel forum posts about the many problems this model has with Windows 8.1. Here's a sample Intel forum posting topic : Intel centrino wireless-n 2230 keeps dropping connection. I've tried over a dozen drivers and other windows updates, and even updated my bios, I experience periodic wifi lockouts.
Summary: Random disconnects, throttled WiFi speed when Bluetooth is enabled. Promises of a driver fix from Intel has produced new drivers that still don't work correctly. My laptop is locked to this card and I can't put a different one in. Thanks Lenovo.
