Wifi and Bluetooth Not Working

[leongws]

Hi, i had problem with my wifi and bluetooth this morning when i switch on the PC.

Was using bluetooth all these while for mouse and earphone while i disabled wifi(AX200) in device manager due to im on ethernet.

What i found is that windows seems to not able to detect the wifi card. I went to device manager and found both the wifi and bluetooth missing. Located both after i click view >show hidden devices. However both are greyed out and got error code of 45 which says not connected.

Had googled and found some cases sort of similar to this but no solution.

Could it be due to certain windows update causing this issue? If no one encountered this, i will probably restore a backup image before this happens (luckily have scheduled a weekly backup) to see is it due to wifi card issue or update issue.

Uninstall both, reboot and let windows detect again

Problem solved. Apparently it is due to ERP enabled in bios. Gigabyte X570 pro wifi got this bug in which once ERp is enable, wifi and bluetooth for some reason will disappear. Need to disable it in bios and shutdown pc, unplug power plug for capacitor to fully discharge and to replug back the cable and it will work again.

All the while i had ERP disable. only few days back i enable it as the backlit for keyboard still lights up even when pc is shutdown. Enable do fix this problem by at the expense of wifi and BT disappearing. Totally forgotten about this issue that was flagged out in overclock.net when i got this MB in 2019.

Mods, kindly close this thread. Thanks
