Did you uncheck every option in the SIP Utility? Or just the default clover config works fine? I have the W311M but it fails to detect any network, and this is what BearExtender shows.

Fully Working with 10.11.4 ( Tenda W311MI) !!

Thanks

Hi all. I have got somewhat near this problem. http://www.alfa.com.tw/products_show.php?pc=28&ps=44 , thats my device. El Capitan 10.11.5., according to the manual from here I have done all. but I have got an error about unsigned kext and cant go any further. thats the log:
MacBook-Air-Mukush:~ Mukush$ cd /System/Library/Extensions
MacBook-Air-Mukush:Extensions Mukush$ sudo chmod -R 755 RT2870USBWirelessDriver.kext

I was trying to add develop mode1 but all in vein, easy kext installer cant help either. Kextstat still show that no kext have been loaded. Is there any way to load unsigned kext? Thx in advance.

http://alfanetworkinc.blogspot.ru I think it may help somebody.
So far so good I found some info about csrutil, here http://osxdaily.com/2015/10/05/disable-rootless-system-integrity-protection-mac-os-x/ may be it will help me tomorrow.

Many thank you has saved my life!

BearExtender works on my D-link DWA-125. But is there a way to hide the BearExtender window on startup? Ticking the 'Hide' checkbox in [System Preferences > Users & Groups > LogIn Items] doesn't work. The BearExtender window keeps showing up on startup & wake.

Working on Sierra 10.12.4 with HP dc7900 SFF and a Tenda W311U dongle (RT3070)

Had to set Country code to 1 (channels 1 to 13) to see any UK networks in Bear Extender utility (v5.4)
WLAN shows up in Network Prefs

Nice !

Is there any solutions do disable program window at system startup?

Got Ralink 3070 to working flinally on 10.12.6, erase first the install, restart then go to system preferences start scan on DWA-140 app
im using powerlink wireless lan outdoor plus. http://www.premiertek.net/products/networking/PL-2712N.html
