BCM4322 / DW1510在Win10下正常使用5G wifi的驱动
Win10自带的BCM4322/DW1510驱动不能很好的支持5G wifi，会特别缓慢。换用Dell的官方驱动可以解决问题。下载地址：https://www.dell.com/support/home/us/en/04/drivers/driversdetails?driverid=wd35f
注意需要在设备管理器中安装。

I faced same problem. Thank you.
I found that, this is an official issue confirmed from Dell:

latest driver download for DW1510（5.100.235.12）：https://www.dell.com/support/home/us/en/04/drivers/driversdetails?driverid=wd35f
This driver support win vista and win 7. If you are using win 10 (like me), following this steps:
1. unzip it (with 7-zip) in a folder. For example, D:\Downloads\Network_Driver_WD35F_WN_5.100.235.12_A37.
2. open "Device Manager" (https://support.microsoft.com/en-us/help/4026149/windows-open-device-manager), Select "Network Adapters".
3. right click DW1510, Select "Update Driver".
4. Select "Browse my computer for driver software"
5. Select "Let me pick from a list of available drivers on my computer"
6. click on the Have Disk... button,On the Install From Disk window that appears, click or touch the Browse... button.
7. choose the wlan subfolder of unzipped driver folder. For example, D:\Downloads\Network_Driver_WD35F_WN_5.100.235.12_A37\Drivers\Win7\WL
8. choose this newly added DW1550 driver of broadcom. next, OK.
9. Once the driver update process is complete, you should see a Windows has successfully updated your driver software window.
10. restart. that's all.
