Did I buy the part since my internal WLAN module did not work in the laptop. Short drivers installed, input WLAN key and I was here again. I'm never more than 10 meters and have always around 80% receive (even if I'm next to the router 20cm). If you go to multiple sites, however at the same time on the road or ships surfing and e-mails you could tell that the part can not keep up with a proper wireless card. But because the part is pretty small and thus can always remain on the laptop, I can recommend it if someone wants to quickly connect a device to the wireless network and will not transfer quite extensive data with it.
