Bluetooth mouse randomly drops out on Aspire S7-191-I may have found the fix!

I believe I have found a fix for this issue and wanted to share:

 

1.  Stick with OEM installed drivers.  The bluetooth and wireless driver updates caused me nothing but trouble with both of those services.  I did a refresh from the Recovery USB stick that I created and did not accept any updates of wireless or bluetooth drivers. I notice they are up to version xxx.234 today and I think it was xxxx.217 that I installed.

2.  Go to Device Manager and Power Management (Advanced) in the Control Power and uncheck every "allow computer to turn off this device" option on the power management tabs for every bluetooth and wireless device and every USB hub in Device Manager.  Do it on every Power Management tab you can find.  In Power settings in Control Panel go to Advanced and set the Wireless to "Maximum Performance on both AC and Battery power. 

 

After doing this, my wireless signal was very strong and never lost a connection.  However, bluetooth mouse would still randomly disconnect.  The fix for that is go to the up arrow for hidden icons in the tray and right click the Bluetooth Setting Icon and select "Open Settings".  Make sure "Discovery" is enabled allowing bluetooth devices to find the computer.  Mine was off by default for security reasons.  Finally, go back to Device Manager under Mice and other pointing devices>HID compliant mouse and make sure they all have the box checked to wake the computer. Once I did that, the first movement of the mouse wakes up the bluetooth service and I don't have to keep resetting it.

 

Note:  I am using a Samsung mouse normally, but worked for the included Acer mouse too.

I am replying to my own original post:

 

I recently updated Windows 8 to Windows 8.1.  As part of the update, I updated the drivers for bluetooth/wireless LAN. This resets everything back to default and I started having bluetooth and wireless issues again.  Bluetooth mouse dropping out and and a dodgy wireless connection.  Can no one build a decent set of drivers for this card???

 

Anyway, If you do a little work you can make it much more reliable:

 

1. Go to bluetooth device settings and allow "bluetooth devices to find this computer".

2.  Go to Device Manager>Network adapters>Qualcomm Atheros xxxx>Properties>Power Management

and uncheck "allow computer to turn off this device to save power" and then go to "advancedtab and set the roaming policy to "very high".

3. Go to Device Manager>Human Interface Devices.  There is a long list of HID compliant devices.  Right click on everyone of them and if there is a Power Management tab, make sure that the computer cannot turn off the device to save power and conversely, allow the device to wake the computer if that is an option.

4.  Do the same for "Mice and other pointing devices and Universal Serial Bus controllers in Device Manager.  Again, right click and any item that has a power managment tab needs to be changed to either not allow the computer to turn off the device or to allow the device to wake the computer depending on the option given.

 

I suppose power management is a wonderful thing... but only in theory.

 

In reality, it's a major PITA with this card and others for that matter-but jumping through these hoops solves the problem.  I am now rocking along and had no further BT or wireless drops and it used to happen about every 5 minutes.
