I had followed this guide and everything was fine till Yosemite. Now I have upgraded to El Capitan and the guide is not working anymore. I used the same wireless driver for Yosemite and installed it using EasyKext Utility. After reboot the pref pane shows no wireless device found.
The kext is being loaded as per kextstatkextstat | grep RT 31 0 0xffffff7f81e18000 0x8000 0x8000 com.apple.driver.AppleRTC (2.0) 30E31171-564B-35AC-930F-385EE149042E <11 5 4 3 1> 70 0 0xffffff7f810c0000 0x98000 0x98000 com.Ralink.driver.RT2870USBWirelessDriver (4.2.9) 6F8EAB45-6166-7B56-95E6-B44FDF8DDE57 <50 41 5 4 3 1>
Please help. Thanks!!
