Attention! This hardware may be excellent if they then works fully in a laptop. Unfortunately, the Intel Centrino Advaced-N 6235 will not work long in all laptops (whitelist in the BIOS). Bluetooth is often not recognized by the device manager. Bonds (tape) to pin 51 (Bluetooth) from - as described in American forums - manages Bluetooth least up in the Device Manager. Get up and running I could part but not. Support of Intel 0.0 (OEM). Also are always interruptions associated with Windows 8 and 8.1 described (driver problems). So I, for my part - equipped with a Samsung Notebook NP300E7A-A01CH (no wifi lid, for taking out the Mini PCIe card must all notebook disassemble) - could the Bluetooth Do not operate despite El.Ing studies after hours , The WLAN function satisfactorily under Windows 7 (64-bit). However, this hardware tends also under Windows 7 to more interruptions than with the previously installed Intel Centrino Advanced-N 6200 (without Bluetooth, original hardware was a Intel Centrino Wireless-N 130 [slow!]). Conclusion: WLAN via Intel Centrino Advanced-N 6200 (very good performance), Bluetooth on CSL - Nano USB Bluetooth Adapter V4.0 (can I also recommend). Of course, the Bluetooth USB Adapter has the disadvantage that it may break at the side exposed position of the notebook and my wife is already canceled.
