So I dug out my 5+ year old netbook, and updated the Ubuntu to release 14.04 (from 10.04) and now it can see the wireless connection and it says it connects to it, but it does not load any pages in the browser, nor does it load the router's site either. I can connect via ethernet.

Please note that I'm a linux newb, I only know to post these commands from googling this problem and seeing that other people posted them - please let me know if there's anything else I should post as well, and if you could explain solutions like I'm a 5-year-old, it'd probably help out a lot!

Solutions I've already tried:

  • sudo apt-get update

  • sudo apt-get install firmware-b43-installer

sudo iwconfig

Your iwconfig output doesn't say anything about power management. Try following:

  1. Launch terminal (Ctrl+Alt+T) and write:
    sudo touch /etc/pm/power.d/wireless
  2. sudo chmod 755 /etc/pm/power.d/wireless
  3. sudo gedit /etc/pm/power.d/wireless

  4. copy paste following into the opened file:
    !/bin/sh /sbin/iwconfig wlan0 power on

  5. Save the file and close gedit.

  6. sudo reboot

Maybe you need to restart NetworkManager. Try sudo service network-manager restart once. It may only be a temporary solution (most likely), or it may work permanently for some reason. (I don't know, maybe networkmanager just needs to be woken up?
