im a real noob with Linux but i really wanna understand and learn it. I bought a Dell with preinstalled Ubuntu 16.04 and bought a USB wifi named ALFA AWUS036NHR version 2. I got a CD-rom with the drivers but i dont understand how i install them with Linux, that is how hard core noob i am. And the problem is that wifi works for like 3-4 minutes then it drops and i have to disconect and reconect to get it to work again 3-4 minutes. What can i do guys? really need you help!

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • Is the WiFi dropping with the USB WiFi or the built-in WiFi? – dsstorefile1 Mar 2 '18 at 12:25
  • The USB Wifi, i havent conected my built-in wifi – Tenne Mar 2 '18 at 12:26
  • I had an issue with a USB Wifi until I shutdown and disabled network manager and switched to using wpa_supplicant directly. Solid now. Check your journalctl output for issues with your dongle and/or WM. But I'm surprised that a new Dell does not have a working onboard wifi. Are you sure? – Stephen Boston Mar 2 '18 at 13:05
  • The ALFA AWUS036NHR can be quite power hungry and perhaps your USB port does not provide enough power. You can try another USB port, another usb cable, a powered USB hub, or you can find some strange USB cables with 2 connections to the computer and only one to the device. – pim Mar 2 '18 at 13:13
