Ubuntu: Weird wireless connection issue



Question:

I am currently having a weird internet connection problem.

I am running Ubuntu 12.04 on a dual boot using Gnome Classic interface and using a wireless usb adapter.

The issue I am having is that my internet connection keeps dropping and then 5 seconds later, it reconnects and only stays connected for 10 to 15 seconds, before dropping again.

  • I have tried checking the additional drivers but it does not list my usb adapter but drivers for my Nvidia Geforce 640 graphics card.
  • I checked in Terminal and my system does list the adapter but there is no GUI for it. The adapter is the MediaLink Wireless-N USB Adapter(Model # MWN-USB150N).
  • I checked MediaLink's website and they do have a Linux driver but after downloading it and reading the instructions it was way too technical and beyond my skills to try to install it since I am new to Linux.
  • I have spent hours reading forums and trying the desktop help to try to solve this.

If anyone could help it would be greatly appreciated.

Solution:1

One person got this to work by removing the rt2800usb module and waiting a minute or so:

sudo modprobe -r rt2800usb
