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.

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

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

Regards,

Mark

Please try the solution from Tom Haddon from this location:

HI thank you for your help; I tried this method:

https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/385293

Didn't work....Still shows only the wired connection network and the hardware drivers shows status as: This driver is activated but not currently in use"
I tried to flip the wifi switch several times (just in case it was the switch) but no luck. Please let me know if there is any other method I can use. TY

Please send us the output of the following command:

sudo lshw -C network; cat /etc/modprobe.d/blacklist.conf

OK here it is:

simmibabar@simmibabar-laptop:~$ sudo lshw -C network; cat /etc/modprobe.d/blacklist.conf
