Question WiFi super slow after changing motherboard

[1myrtille]

Hi,
I had changed my motherboard to a Gigabyte A320M s2h rev1.0 and ever since I have been getting super slow internet speeds.

Full spec :
MOBO Gigabyte A320M s2h rev1.0
CPU Ryzen 5 3600
RAM 16GB corsair vengeance
GPU EVGA 1060 SC 6GB
PSU Corsair VS450

Realtek Diagnostic showed that the WiFi adapter was running on half duplex mode. (Netgear A6100)
Could anyone tell me what the issue is?

1. On the Start menu, click Control Panel.
2. Click Network and Internet.
3. Click Network and Sharing Center, and then click Manage network connections.
   The Network Connections folder opens.
4. Right-click the relevant network connection (by default, Local Area Connection), and then click Properties.
   The Local Area Connection Properties dialog box opens.
5. Click Configure.
   The properties dialog box for the adapter opens.
6. Click the Advanced tab.
7. In the Property list, click the property that corresponds to the connection type, such as Connection Type, Duplex Mode, Media, Media Type, or Link Speed & Duplex, depending on the adapter's attributes.

Change it to Full Duplex.

There isnt an option to change it in the advanced tab for my Wifi adapter. There are only seven property types available and none of them allow to change the duplex mode.
