Wifi & Bluetooth Disappeared B550 ITX/AX Phantom

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Wifi was still working fine last night, but when I turned on the PC this morning Wifi was gone, and I had to plug in the ethernet cable.

I checked under device manager and also in control panel, it seems both Wifi and Bluetooth are gone. Only change from earlier this week was windows updates/patches. I rolled it back already but I'm still not getting the wifi/bluetooth back.

Anyone can help pls?

	I have also tried to reinstall the intel ax wifi driver and the AMD chipset software. I also attempted to install the "Intel WLAN and Bluetooth driver ver:21.80.0.3" from the ASrock support website, but I have no idea how to install this.

	The same thing happened to me on Taichi X570 for Intel I211 lan. I don't know if my solution will work for you chipset. In my case Windows shown a device with wrong ven and dev. I simply reflashed the bios.

	Hi, i have the same problem on my b550 phantom gaming 4/ac. I think it has to do with power connectors and/or the m.2 wifi card. Did you find a solution to this problem?

	Still an issue, but I suspect it has to do with the onboard LED settings but not sure The interim fix is to switch off the PSU, then it'll come back on every time
