I have a Samsung Series 9 NP900x3A. I recently replaced the factory wireless network card with the Intel Centrino Advanced-N 6230. I got everything working - WiFi, WiDi, and Bluetooth. But recently the Bluetooth stopped functioning, and now it's not even available in the Device Manager. Every attempt to repair of remove and reinstall fails because I can't do those when it's not functioning and the system doesn't see it as even existing. My Windows (running 7 Home Premium) notification icons now list the Bluetooth as "Window Host Process (rundll32)" with "Bluetooth" in italics underneath it. I have all the updated drivers, but nothing seems to do the trick. Anyone else have this issue? And how can I do a repair or a reinstall of the driver if the Bluetooth software itself won't let me perform that through the Windows Uninstaller?
It's a new one I put in myself. The bluetooth actually started working once I was able to uninstall the drivers and software via CCleaner. I then reinstalled everything, and after some random restarts, it kicked in again.
What version is the driver？
Try this page.
What Wi-Fi card did your computer use previous? Is it an combo one integrating Wi-Fi and Bluetooth 3.0?
Yeah, it was a Broadcom that had Bluetooth and Wifi, but no Widi (which was my reason for swap in the 6230). The driver I used was the Intel® PROSet/Wireless Bluetooth Software for Windows 7 64-Bit.
Could you verify something for me?
In the Device Manager, go to Intel Centrino Advanced-N 6230, right click the adapter, switch to Advanced Tap, if I change the 802.11n (2.4GHz) channel bandwidth from Auto to 20MHz, the adapter would disappear for a while, until I click the Scan for new hardware, then it shows up.
Would this happen to yours?
Strange! Do you use the Intel My Wi-Fi tool to configurate your wireless network?
Maybe I got a Intel Centrino Advanced-N 6230 with some flaw.
Maybe your card got some hardware problems, too.
There is similar case here. He installed the same card, but the bluetooth part didn't work properly.
Just installed my 6230 and bluetooth was working under the microsoft drivers and the intel drivers but after a reboot the bluetooth has disappeared completely. It can not be found in device manager etc. Also cannot remove the drivers since the "device is not present".
Ive got exactly the same problem. I may try Win 8 to see if the problem resolves, which may indicate that it is this specific set of hardware (7 x64 + 6230) which causes this problem.
As for uninstallation, use microsoft fixit: programs that do not install/uninstall
However, I have installed/uninstalled, deleted program files and deleted whatever intel/bluetooth registry entries I could find. The problem stops for a bit but resumes quickly. I hope we can still fins a solution for this, however, Intel doesn't seem like it will help so it is upto us .
I have the same Problem N 6235 with Bluetooth 4.0 on AMD based Notebook, installed "BT_2.6.1210_e64" for Windows 8 and it worked about 1 Day. Today it first said "Treiber abgeschaltet Cdoe 18" (means "Driver switched off" Code 18)... after uninstall and reinstall now it says "Code 28"...
What is wrong with it???
Could you uninstall 2.6 BT drivers from Intel, reboot and check few reboot cycles to see if it works consistently?
May I ask you what features of BT you use? Depending on that, you may not need Intel BT drivers at all.
