Hello there! This is my first post here so hopefully I'm not writing in the wrong thread. I will apologize if that happens. I have finally got into Kali Linux, but unfortunately I have found so many problems that I got desperate.
I have bought a Tenda UH150 (uses Ralink RT3070), so that I would be able to get into Kali's internet tools and so on. I've installed it on a second partition (I'm dual booting it with Windows 8.1) and everything went perfect, except that I couldn't connect on the internet using wlan0 connection type. It was asking me to enter the "ESSID" and the password so that I could connect, but all my tries were in vain, so I just moved on by using the eth0 connection type. Surprinsingly, when I entered the Kali's menu, the Wi-Fi was working without any problems, but the ethernet was disabled (Device not managed). I have found a fast sollution to fix it, and when I finally fix the ethernet problem, after I restarted the network manager, the Wireless Network stopped working having the following error: "Device not ready". I have tried to revert the setting, but since then I couldn't have done anything.
I just can't understand why is this happening and why enabling the ethernet connection kills the wireless one. I'm a super newbie at Kali Linux, so hopefully there will be someone to help me solve all of this. I've been searching for other fixes for hours, but still no success. If there's necessary to add more information, I'd gladly do it so. Thank you so much for reading.
