Unfortunately, I belong now to those who have a problem with the Bluetooth connection. I have a Dell Inspiron 17R SE 7720 upgraded with the network adapter 6235 with Win 8.1, because I want to use the 5 GHz option. Intel driver version is 15.15.0.1 from 17,01,2014. So far so good, WLAN works! Also. Unfortunately, I can make with my Sony Xperia with Android 4.4.4 can not connect via Bluetooth with your notebook. Which, interestingly, a link is displayed, the device can be coupled also. But the phone is not abgezeigt in Explorer, and there is no data exchange possible via Bluetooth. On the Intel side, there is only succinctly (several times since 2012) not intended for end users, but only for OEM customers, is this network adapter, there is no support. In my opinion, Intel should it then but not offer individually. Maybe I get it still there, but it is very annoying. No trace of plug and play with this device. 3 stars for WLAN's.
