After the Sonoma 14.5 update, many users experienced wifi connection problems. I was one of them. I got everything back in place with “RT2870USBWirelessDriver.kext” among the kext.s I used completely by chance. moreover, AirDrop works smoothly. for your information. if it doesn't solve the problem for you, I can share my own EFI folder, friends.
pay attention to the order, airportltlwm.kext is down below as usual, RT2870 kext is working with SMCBattery on it. I moved it a few times and everything is broken again.

Stay with love. by the way I apologize for my English.
