    Multiple devices connected to PC via Bluetooth are lagging

    I have a PC with Gigabyte Z390 AORUS PRO WIFI (rev. 1.0) motherboard, which has a built-in Intel Wireless-AC 9560 network adapter with Bluetooth. Windows 11 onboard. And I have a set of Bluetooth devices which I’d like to connect to my PC: Microsoft Designer Bluetooth Desktop (keyboard + mouse), HyperX Cloud MIX headphones and Xbox Elite Wireless Controller Series 2 gamepad.

    When I built my PC in December, 2020, I connected my keyboard and mouse, and they worked without issues. Then I bought the headphones, and all three devices worked fine. But when I got my gamepad, I’ve noticed that when all four devices are connected to PC via Bluetooth, couple of them (or at least one) start lagging. For example, when I play a game with the gamepad, the sound in my headphones sometime disappears - even though I don’t use the mouse or keyboard (but they still connected). Or my gamepad disconnects and then reconnects to PC. It is especially noticeable in heavy scenes when too many actions are performed at once, but they occur in other cases, too. Even the game itself lags when my devices are disconnecting and reconnecting (and this is just Ori and the Will of the Wisps).

    I haven’t used my PC for about 7 months. Yesterday I turned it on, updated Windows, apps and drivers. But now even though only keyboard and mouse are connected via Bluetooth, my mouse is constantly stuttering - even without a single app opened. And when I connect my headphones and watch a video, they work fine only when I’m really close to the PC - if I just take one step from the table, the sound disappears.

    I have a similar issue with my old laptop from 2012 with Intel Centrino Wireless-N 2230: when my mouse (Razer Atheris) and headphones (Jabra Elite 85t) are connected at the same time, one of the devices is lagging. When I connect only one of them, it works fine.

    The question is, what exactly is the problem? Is the network adapter too weak? I have 3 PCI Express x1 slots available in the motherboard - if I buy a good external network adapter, will it help to keep all my Bluetooth devices reliably connected? And why did this issue become worse after 7 months without using my PC? And yes, I know that Bluetooth in general is not as reliable as wired connection, but I’d like to use it anyway (if it is possible), since that’s convenient for me. Thanks in advance for any useful piece of information.

    Other important components of my PC are: Intel Core i5-9600KF CPU, MSI GeForce GTX 1660 Ti VENTUS XS 6G OC GPU, Corsair VENGEANCE® LPX 16GB (2 x 8GB) DDR4 DRAM 3200MHz C16 memory kit, Samsung 970 EVO NVMe M.2 SSD 500GB drive.

    see if anything here sheds some light on your situation.
    learn about bluetooth More than a kilometer. Less than a meter. The effective, reliable range between Bluetooth devices is anywhere from more than a kilometer down to less than a meter.


    you may just not have enough bandwidth on the Bluetooth frequency.

        Yeh, because my problem isn’t solved yet. I’m asking if upgrading my network adapter will help me to keep all the device reliably connected? Maybe there are some people here who can tell me if my current adapter is good enough, and if upgrading will help?

          the current wifi/bluetooth onboard chip may not be good enough to run four bluetooth devices.
          if you disconnect one device and the lagging stops, I guess that answers the question.
          sadly you are only going to know for sure by getting another bluetooth card and seeing if that helps.

          unless others have any ideas? @Pyro @PeterOz @Malnutrition @Bastet

            Remove the headphones & just connect the xBox controller does the problem remain? If yes then the controller may be the problem.

              Try removing on device at a time like Bastet suggested, but do it will all of them, gamepad, mouse, headphones, etc.

              Does one do something while others don’t?

                  Yeah, when I disconnect the mouse, everything else works fine. Looks like this is part of the issue. Thank you.

                  It is obvious now that I should try to add a new Bluetooth adapter to my setup if I want to use all the devices at the same time. But I still have one final question. Is there a parameter in the network adapter that can tell if this adapter is better than another one? I mean, how can I choose a better solution? What parameters should I compare? I’ve read an article suggested by @Bruce - seems like there are a lot of different parameters, but on the Intel Arc website, only Bluetooth version is mentioned…

                  It’s OK if you can’t help, I’ll just buy a newer and more expensive one - but it would be awesome if someone could suggest anything in this regard.

                    your current bluetooth adapter is embedded with your wireless adapter - an all-in-one solution.

                    you could either just get a USB bluetooth adapter like this; Targus Bluetooth 4.0 Dual-Mode Micro USB Adapter - ACB75AU | Mwave
                    it says it can handle 7 connected devices. costs $13 (AUD) so nothing to lose.

                    or you could go for another AiO solution like this; https://www.mwave.com.au/product/tpl...dapter-ac31635

                    typically, the more you spend, the better the device - speed, range, connections, etc.

                    the latest bluetooth gen is 5.0 which your PC has. The above adapters use 4.0 or 4.2, which may be a better fit with your devices.
                    at the end of the day, it’s a suck it and see exercise.

                      OK, thanks a lot for your help ??? @Bastet, @Pyro, @PeterOz - thanks all of you ??? I’ll try to install a new adapter, hope this will help ???
