When sending a file with a WiFi adapter, the number of packets sent according to Powershell is much lower than the expected value

Question

I use Windows 10 and a D-Link WiFi adapter. I have tried with a TP-Link adapter and the results are similar. On the WiFi adapter I have disabled all protocols except IPv4.

I start the Wireshark capture, connect the Wi-Fi adapter and after a few seconds the captured packets are:

Wireshark: 688 packets captured

Statistics with Powershell:

After sending a 10 MB file (10485760 bytes) the results are:

Wireshark: 8255 packets captured

Powershell:

Get-NetAdapterStatistics -Name "Wi-Fi 2" | Format-List -Property "*"

• Unicast bytes sent according to Powershell: 11153902 - 735 = 11153167

• Unicast packets sent according to Powershell: 575 - 10 = 565 packets

• Packets sent according to Wireshark: 8255 - 688 = 7567 packets

The number of packets sent according to Wireshark and Powershell is very different. For some reason the reading of packages with Powershell is very small. I am doing something wrong? Thanks.
