unable to see wireless network

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 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.

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 aptitude update; sudo aptitude 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 'ound|irmware|eth|ath|wl|ipw|b43|witch|ndiswrapper'; iwconfig; grep b43 /etc/modprobe.d/*; grep wl /etc/modprobe.d/*; sudo hwinfo --netcard ; sudo /etc/init.d/networking restart

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.

NOTE: be sure your onboard pc hardware wireless switch, if there are any, is active

According to the output you sent, the Linux kernel is currently not detecting any wireless card on your PC.

Please make sure that wireless is enabled in the BIOS and make sure that wireless is not disabled by a hardware switch/button located on the side or bottom of your PC.

Mark,

Thank you for your assistance. I am using Phoenix BIOS F.20 which does not allow me to access any advanced features in it. I did load the default setting while in there but nothing has changed.

My laptop does have a wireless switch on the front and it is showing to be on. I have turned it off, waited a few minutes, and turned it back on without my Ethernet cable connected and I get no response.

can you reboot with the switch off, then get logged in and then turn it on. Can you then give the output of:

dmesg | tail -n 20; sudo lshw -C network

Thanks.

I rebooted with the switch off, my laptop automatically turns the switch on upon restart, but I turned it back off before logging in and then turned the switch on again after login. I unplugged my Ethernet during this process. Below is my result:
