    I have a dual boot on my laptop, windows 8.1 pro and ubuntu 13:10, and I use realtek usb wi-fi adapter for browsing. when I am in windows, the internet is very fast. but when switched to ubuntu, it is connected, but the signal is weak and can not open the internet. WHAT IS THE PROBLEM? thanks

    I had a similar problem, no wifi at all (broadcom) in a previous version. I solved moving to Fedora. Manjaro is an excellent version, worthwhile trying it.

    No, you did not solve the problem. You avoided it. The OP wants to get the wireless working on his/her system of choice. Switching distributions is the OP's choice to make if the problem cannot be fixed.

    I experienced the same problem on my laptop (which isn't awesome to begin with, but still, it worked great with Windows). I made the switch to LinuxMint, which was better, but still not great. I'm not sure what the issue was but I'm interested in knowing how to make it better.

    Thanks,

    Code:
    sudo iwconfig


    This will list the available wireless interfaces in your system. Now check out your wireless device name here, usually it will be wlan0

    Now type the command

    Code:
    sudo iwconfig DEVICE_NAME power off


    What this essentially does is switch off the power management by Ubuntu for your wireless device.
