新装主机的蓝牙不能正常连接

[liuzhiqiang]

华硕X399主板，AMD平台，装了comfast AX200无线网卡，但蓝牙不能正常连接，2.4GUSB连接有延迟，请问怎么解决？已经试过更换蓝牙驱动，不可以。和OPPO手机连接，配对上之后可以连接，但互相传文件不能成功，设置里打开蓝牙搜索设备偶尔可以搜索到鼠标但不能连接上，蓝牙耳机搜索不到，这里截图可以看到虽然已经成功配对了安卓手机，但不能连接，罗技键盘只能通过USB2.4G连接。现在重新打开蓝牙搜索，一直显示在搜索页面但没有搜到任何东西，可以确定鼠标耳机没问题蓝牙已经打开

Hello @liuzhiqiang

Thank you for posting on the Intel® communities.

请注意，我仅能以英语提供支持。我使用了一个 Web 翻译工具来翻译此响应，因此，可能有一些不准确的翻译。此外，我们可能无法翻译线程附带的屏幕截图。

Could you please confirm the following details?

1- We understand that there are troubles detecting and connecting devices to the computer using Bluetooth. Is this correct?

2- Based on your description, we understand that you are using a third-party wireless card: Comfast* AX200 Wireless Network Card. Is this correct?

Is it a PCIe wireless card like the ones in these examples: Example 1*, Example 2*? Could you please share a link as a reference?

Did you integrate the wireless card on the computer?

3- What is the exact and full model of the ASUS* motherboard?

Best regards,

我查到USB3.0设备的使用和2.4G无线设备的使用可能有冲突，为什么5.0蓝牙也会出现类似情况

2.4G Wireless and Bluetooth share an antenna, transmitter and frequency range. USB 3.0 uses the very same frequency range for its signal transmission. If the USB cables are not properly insulated (and a great many of them aren't, unfortunately), then they *will* act as antennas and the signal, because of the common frequency range, *will* interfere with Wireless and Bluetooth transmission.

I have seen plenty of warnings that many of the PCIe M.2 Wireless adapters will not work properly if plugged into anything other than a PCIe x1 slot. I have experienced this problem myself (it was a *real* problem in an mITX board that only had one x16 PCIe slot). If your installation is not into a PCIe x1 slot, I suggest you move it to a x1 slot and test again.

Hope this helps,

Hello liuzhiqiang

Thank you for your response. We hope that the information provided by n_scott_pearson has been helpful.

Also, after checking this further, this Comfast* CF-AX200 PCI-E wireless network card is actually considered a third-party device. Despite it comes with an Intel® Wi-Fi 6 AX200 chip and it may use our generic drivers, the Original Equipment Manufacturer (OEM) is Comfast* and this is what we call an OEM integration (Intel sells the chip to the OEM and they design this PCIe card that includes all the electronic to convert from M.2 to PCIe, they integrate the chip in the PCIe card and provide their own antennas and maybe customized drivers. They also label it with their own brand/model).

We recommend using the drivers and software* provided by your OEM Comfast* and addressing this behavior to them for proper assistance.

You may also check with the motherboard manufacturer ASUS* for compatibility information. For your convenience, here is the link to ASUS* Support. 

Having said that, we will proceed to close this inquiry now from our side. We will leave the thread open in case other users want to participate but this thread will no longer be monitored. Thank you for your understanding.
