Hi,
Good for you to follow the public document at the first hand! The reason why you still cannot create an external virtual switch needs further troubleshooting and here are some tips you could try:
Firstly, I would like to collect your KB number of your current Windows version to further check the non-compatibility issue of your wireless NIC and your Hyper-V host version.
Secondly, any WAN miniport devices such as WireShark / NCap are supposed to be removed when you set up an external virtual switch. Check if you have any of these network devices, if so, I’d like you to remove them and run Microsofteasyfix20159.mini.diagcab to set up your external virtual switch again.
More information about WAN miniport devices can be seen from

Thirdly, try to use PowerShell commands to get the information of your network adapter and Hyper-V virtual switch to see whether you have actually created successfully. Then try to use PowerShell to setup an external virtual switch.
A. To get the information: Get-VMNetworkAdapter
B. To create an external virtual switch: New-VMSwitch -name ExternalSwitch -NetAdapterName Ethernet -AllowManagementOS $true
If you still cannot work out the problem, then I am afraid that it is quite hard to solve the non-compatibility issue with wireless NIC. The usual answers of driver updates, software version updates help some but for those trying these ways from a wireless network adapter there seems no solid fix.
