Dannydeman Posted June 16, 2016 Share Posted June 16, 2016 I have the AzureWave Broadcom BCM94352HMB chip installed on my GA-H87N-WIFI. Bluetooth and Wifi both work. Unfortunately I noticed a huge bug. When I am downloading at highspeed (when it goes above 60mbit on speedtest.net) my bluetooth connection gets very choppy (mouse pointer is lagging etc.) When I turn off Bluetooth or disconnect the mouse, the downloadspeed is higher as well. How can I fix this? I already tried different antenna's, problems is the same. Link to comment Share on other sites More sharing options...

Follow a guide online, some very good exist in this very forum. Link to comment Share on other sites More sharing options...

Well, open IORegistryExplorer.app and find your "XHC" label on this tree list. Take a screenshot with it expanded and post it here. I'll be able to tell you if you're OK or you need to do some work.

Traace Posted June 16, 2016 Share Posted June 16, 2016 Both, the Wifi and the Bluetooth signals interfere with each other due their frequencies. There are Router/AP's out there mostly with a dd-wrt based firmware which has a special "bluetooth compatibility mode" for such dual chipped cards with one antenna. Are u sure that these issues are not happen on Windows/Linux too? Your card is connected via mPCIe, therefore this has nothing todo with USB...

Mini PCIe cards like Wifi+BT use the USB Bus to communicate with the rest of the components. Take a look at "HS13" on the attached photo. Link to comment Share on other sites More sharing options...
Dannydeman Posted June 16, 2016 Author Share Posted June 16, 2016 USB was fine I guess, because I solved the problem. I changed my internal network to 5GHZ and now the Bluetooth lag is gone. I still think it's weird that it could happen, maybe Apple's driver isn't that good? I saw some complaints from 'real' Mac users as well. Link to comment Share on other sites More sharing options...
meziatto Posted June 26, 2016 Share Posted June 26, 2016 Bluetooth lag also happens on my MacBook Pro 2011 Late. Sometimes none, sometimes acceptable, and sometimes mouse locks down based on router. Link to comment Share on other sites More sharing options...
