gigabyte b660

I have a B660 Gaming X AX from Gigabyte and installed the WiFi, Bluetooth, and LAN drivers onto my system, but windows 11 Home says I ´Cant connect to this network.´ I tried both the antenna that comes with the Mobo and a USB WiFi adapter but neither appear to work! I’ve tried many things now...

Sorry if this is the wrong place, does anyone know what type of splitter I need to connect the fans to the motherboard? The normal 4 pinn PWN cables don't seem to fit and there are no extra cables that would fit.
