Unable to connect to wireless networks

Postby Vrsabha on Mon Jan 07, 2013 3:44 am

Dear friends,

I have got a dual boot laptop running XP and Linux Mint 14 Cinnamon Nadia. Four days ago, a friend of mine installed Linux Mint 14 Nadia. The first day everything was fine. However, the second day I lost my wireless connectivity. When I click on Wi-Fi connection icon on the panel, I get a message “The cable unplugged”. (Obviously, it is not unplugged as I can use XP for Internet traffic.) What do I have to do in settings so that my laptop (Dell Inspiron 1545) recognises wireless networks and gets connected?

Thank you
Vrsabha

Uh, I am afraid that I don't understand your message. I am a total newbie in Linux Mint. Could you give me step-by-step guidance?

Open a terminal

Use your mouse to paste the code I gave you in to it and hit enter

Post the result for each....

Dear Novell,
here is what I got after pasting those commands into Terminal. But still, there is no connection. What next should I do?

Either one of two things

1. You need a wired connection
Paste this in to a terminal
Code: Select all
sudo apt-get install firmware-b43-installer


Then this
Code: Select all
sudo modprobe -rv b43

Code: Select all
sudo modprobe -v b43

Give it a minute and it should come to life

Or

2. PM me for another method

I tried the solution posted by caf4926 but it did not work for me. If his solution doesn't work for you, I found one that did work for me and hopefully will be of use to others:
