Is it possible to have working WiFi on a Ubuntu Live CD?

I can't click on network (networking is disabled).

If I type in iwconfig, the result is:

 Lo no wireless extensions.
erh0 no wireless extensions

Wlan0  IEEE 802.11abg ESSID:OFF/ANY
Modę:managed access point: not-associated tx-power=0 dBm

Power management:on
  • Can you list the chipset used and model of the wifi adapter for your laptop? You can do this with lspci | grep -ai -e wireless and lsusb.

It's simple in Ubuntu 12 using a LiveCD/USB.

  1. Go to System settings → Software sources → Additional drivers
  2. Select any available option other than "Do not use the device"
  3. Hit "Apply changes"

Enjoy your WiFi.

  • When I click on "Apply Changes", the option toggles back to "Do not use the device" automatically. Do you know a solution for this? Jul 12, 2018 at 19:17

It's possible. Check that your hardware switch is not put to off. If toggling it does not help, turn Wireless Networking to on in the Network Manager.

To check whether wireless networking is blocked, run rfkill list in a terminal and be sure that it looks like:

0: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: no

(note the "no")

  • the result is: HP WiFi wireless LAN Soft blocked:no Hard blocked:no

Yes it can, I've done it a lot of times. If you run the liveCD and then wait about 2 minutes the Additional Hardware application will let you know you have drivers to install. Alternatively you can manually go to the Additional Hardware app by searching for it.

  • But In Additional Hardware list is empty

  • The drivers should be okay, since iwconfig already lists wireless configuration. Oct 29, 2011 at 21:47
