Hello all, I?m new to this forum. I was having a lot of issues getting my RT3070 to work in Kali Linux on a VirtualBox , MacOS. It would always say ?Not Connected ? when trying to connect via WiFi, while the ?Wired? connection worked fine. If you typed #ifconfig it wouldn?t list wlan0 at all. However, booting from a live USB I realized it worked fine, with no driver install necessary, just plug and play.

I tried every possible fix under the sun, and in doing so it made me extremely familiar with both VirtualBox and Linux command line/O/S.
I tried network-manager restarts, putting wlan0 up and down, trying to install drivers , etc.. everything. Still no luck.

The solution is so easy it?s a joke. When you plug in the USB adapter, it defaults to USB 2.0 in the VirtualBox settings > Devices > Ports menu. Simply change this to USB 3.0 , and your issue will be fixed. You might need a reboot.

You don?t have to do anything to the host (MacOS) , no need to install drivers anywhere, simply change this setting and your USB ALFA RT3070 will function in Kali Linux within the VirtualBox.

There is a lot of confusion over this topic, i hope this helps. Pls let me know if it does by responding to this post!
