Windows 7: Broadcom Bluetooth and Intel wireless 6205 conflict !!

Broadcom Bluetooth and Intel wireless 6205 conflict !!

Hi all
I am using a Lenovo X1, 129126U for over a month now I am having problems connecting the a4tech bt310 bluetooth mouse to the machine, previously it used to be fine but then suddenly the bluetooth components dissappeared after several attempts and uninstalling and reinstalling drivers I have been unable to detect and connect any bluetooth devices. Moreover after the last driver update the wireless connection suddenly got dropped as soon as I started the bluetooth device detection process. I uninstalled and updated the wireles drivers but still no change, changed the wifi channel to 5.2g but still no change. Initially I suspected issues with Lenovo Access Connections and had uninstalled it as well but there is still no resolution.

The problem: as soon as I start the bluetooth detection process the wireless connection is dropped and only reconnects when I switch BT device off and close the BT connection pane.

Drivers listed below
Bluetooth Broadcom drivers updated to 6.5.1.2700,
Microsoft Bluetooth Enumerator driver updated to 6.1.7601.17889,
Intel centrino wireless 6205 driver updated to 15.4.1.1,
Microsoft Bluetooth Personal Area Network driver 6.1.7600.16385,
Microsoft Bluetooth Device RFCOMM Protocol 6.1.7600.16385.

Hi all

I am using a Lenovo X1 model 129126U. Since last three months I am having problems connecting any bluetooth device to the machine, previously it used to work fine but then suddenly the bluetooth components dissappeared after several attempts and uninstalling and reinstalling drivers I have been unable to detect and connect any bluetooth devices.

The original issue was that all BT components registered in the BT module suddenly disappered and when I tried to re connect the BT devices nothing happened. I continued to have this issue and was experiencing issues only in detecting and paring BT devices but more recently I had uninstalled and reinstalled all the drivers (bluetooth as well as wireless) I have started to experience a new issue that is as soon as I initiate the BT pairing activity my wireless connection gets dropped. Considering there may be a conflict between BT and WIFI, I even disabled the wireless and as discussed on various forums even changed the settings for wifi channel to 5.2g and tried to add BT devices but nothing happens except for dropping of the wifi connection as soon as BT pairing starts.

I called Lenovo support and after discussion they even remotely connected to my machine and checked all the drivers and components but couldnt find any issues with the drivers nor any conflicts in the hardware components. They suspected that this is due to an MS update, whereas I suspect that the issue originated after the bios update version 1.66.2.01 or it maybe due to Intel Chipset Support update version 9.3.0.1021. While have further updated the bios to version 1.68.2.02, I believe this issue has not be addresed or corrected. While all of these are my assumptions I have yet to find a response or assistance that can help me find a solution to my problem.

I would appreciate if some assistance and guidance may be provided in resolving this issue.

Current status of drivers on my machine
BIOS -8MET68WW(1.68)
Bluetooth Broadcom drivers updated to 6.5.1.2700,
Microsoft Bluetooth Enumerator driver updated to 6.1.7601.17889,
Intel centrino wireless 6205 driver updated to 15.4.1.1,
Microsoft Bluetooth Personal Area Network driver 6.1.7600.16385,
Microsoft Bluetooth Device RFCOMM Protocol 6.1.7600.16385.
