Wi-Fi in Ubuntu Studio

Hi,

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 lsmod. 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.

Tip: If you have a wheel mouse or 3 button mouse you do not need to type commands into the Terminal. Highlight the command written on the page. Move your cursor anywhere in the Terminal and press the wheel or middle button. Automatic Copy and paste! No spelling mistakes! No Typos! No other errors!

sudo apt-get update; sudo apt-get install hwinfo grep; sudo lshw -C network; rfkill list; sudo iwlist scanning; cat /etc/network/interfaces; cat /etc/lsb-release; lspci -nn; lsusb; sudo lshw -short; uname -a; dmesg | egrep 'acx|at76|ath|b43|bcm|CX|eth|ipw|irmware|isl|lbtf|orinoco|ndiswrapper|NPE|ound|p54|prism|rtl|rt2|rt3|rt6|rt7|usb|witch|wl'; iwconfig; cat /etc/modprobe.d/* | egrep 'acx|at76|ath|b43|bcm|CX|eth|ipw|irmware|isl|lbtf|orinoco|ndiswrapper|NPE|p54|prism|rtl|rt2|rt3|rt6|rt7|witch|wl'; sudo hwinfo --netcard ; cat /var/lib/NetworkManager/NetworkManager.state; sudo lsmod

Step 3: Please post results (copy/paste terminal output) on this thread. The troubleshooters here need to see the full Terminal output from running the above command.

Step 4: Please also specify the exact model and make of your PC (if known) on this thread

Regards,

Mark

but it is not showing wifi connections or available signals, please help me to connect wifi,
where i can find the available connections, as like in ubuntu it is not showing the available signals,

i am a beginer un ubuntu studio, please help me in details

If you use a wired interface and install wicd then reboot. You can tell wicd to use eth1 as the interface, network manager usually expects wlan0 as the name.

will you please describe were i will find these settings, because if i have plugged in the RJ 45 cable the pc automatically take connection, after removing it no wifi connection will take & it is not showing any wifi options in anywere in the pannel or desktop

where can i find available wifi connections in ubuntu studio. in my pc available connections are not showing

sorry, problem is mine,

i have installed wicd and now everything is working fine,

Thanks for all to helping me.

Thanks Mark Rijckenberg, that solved my question.

Sure I advised wicd, but you got the gold ad that's what counts ;)

Peace
