Wireless adaptor

The community documentation has vast information on this topic.

https://help.ubuntu.com/community/WifiDocs/

If after reading basic docs you are still in trouble...

Please first connect your network card to the wireless router using an ethernet cable (also known as a LAN cable).

In order to gather essential troubleshooting information about your wireless card, please follow this procedure:

Step 1: Open Terminal from "Applications->Accessories->Terminal"

Step 2: Please copy-paste the following command from the https://answers.launchpad.net/ubuntu website in Firefox into the Linux Terminal. Do NOT copy-paste from the Email message into the Terminal, as that will only copy PART of the command. The command STARTS with the word sudo and ENDS with the word restart. So please copy-paste the ENTIRE command below from Firefox into a Terminal, press <enter>, then enter password when sudo asks for password, then press enter again.

sudo lshw -C network; sudo iwlist scanning; cat /etc/network/interfaces; cat /etc/lsb-release; lspci -nn; lsusb; sudo lshw -short; uname -a; dmesg | grep ound; dmesg | grep b43; dmesg | grep wl; dmesg | grep witch; iwconfig; grep b43 /etc/modprobe.d/*; grep wl /etc/modprobe.d/*; sudo /etc/init.d/networking restart

Step 3: Please post results (copy/paste terminal output) on this thread

And wait for Mark Rijckenberg answer...

Then you can try to read the already answered question here https://answers.launchpad.net/ubuntu/+source/gnome-nettool

Hi, I'm having a problem with my wireless - wireless is activated by a switch above the keyboard but this won't turn on at all since I installed ubuntu.
I followed your instructions above (and I've tried several other fixes too to no avail) and here's what came up:

The current thread was for helping Ed Gall more than 4 years ago.

It is confusing to start mixing several different issues into the same thread.

That is why we do not work that way (in order to avoid confusion).
