Wireless Network not working

Asked by Seraph

I have a Sony VAIO VGN-A190 Laptop (1.70 GHz Pentium M, 512 MB RAM, 80 GB Hard Drive, DVD+/-RW/CD-RW Drive) .. and the wireless was working when I first hooked it up. But when I turned it off after the first use, it won't detect any wireless signal. Even though the connection is in the other room; just a wall separates me from the connection. I've tried restarting things, turning off the W/LAN and restarting, then turning it back on.. restarting my router.. I've done everything, including making another administrative account on the computer with no results?
I really want to use wireless on this laptop since it's pretty important. This has become incredibly annoying.

What could it be?

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 this page in browser 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 dist-upgrade;
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 dpkg --configure -a; sudo apt-get -f install; sudo apt-get update; sudo apt-get dist-upgrade;

Then reboot your pc and test if your wireless card is detected, if not continue from the step 3 below

Step 3: Please copy-paste the following command from this page 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 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 'ound|irmware|eth|ath|wl|ipw|rtl|rt2|b43|witch|ndiswrapper'; iwconfig; grep b43 /etc/modprobe.d/*; grep wl /etc/modprobe.d/*; sudo hwinfo --netcard ; sudo lsmod; sudo /etc/init.d/networking restart

Step 4: 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 5: Step 4: Please also specify the exact model and make of your PC (if known).
