Can not get wireless on Linux Mint 15

[mattfaria12]

Fresh installation of Linux Mint 15. My only problem thus far is I can not get wireless to turn on and connect to my network. When connected directly through ethernet, I am able to connect. But I would like to connect wirelessly also. Can someone please show me how to configure wireless and connect?

What is the model of your wireless? There's a series of Wi-Fi modules that were dropped in the 3.08 kernel, so you might have to upgrade that to get your wireless up.

Whats the command to get the wireless model? And i did a "sudo apt-get upgrade" yesterday, thinking that might fix the problem. Same story though.

Code: Select all

matt@matt-Lenovo-3000-G530 ~ $ iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.

I did some research and found the "iwconfig" command. Above is the output

Let's see the output of:

Code: Select all

sudo lshw -C network

[Ronshere]

if you have Broadcom wifi then do this:
Bring up the Terminal and run these commands

$ sudo apt-get remove bcmwl-kernel-source
$ sudo apt-get install linux-firmware-nonfree
$ sudo apt-get install firmware-b43-installer b43-fwcutter

Now load the b43 module
$ sudo modprobe b43

To make it start it automatilcally

$ sudo su
# echo "b43" >> /etc/modules

Reboot

Output for the command "sudo lshw -c network"

Seems I have Broadcom. Will try Ronshere's method

[mattfaria12]

Hey Ronshere your method worked. Is it cool if I ask to explain what each command does? Just so i can get more familiar with Linux

[cjorsinger]

mattfaria12, you can look that up yourself by using the man command, as in type ;

Code: Select all

man modprobe

at the command line to learn about the modprobe command. Just look for the parameters Ronshere included in that group of commands. The short version is that he had you remove some Linux drivers that were not working for you, replaced them with some that were better for your wifi device, along with the "non-free" firmware that makes it go. The last echo command requires a bit of explanation; it makes sure that Linux loads that driver when it boots.

[mattfaria12]

Okay i will do it myself. Thank you for the explanation.

if you have Broadcom wifi then do this:
Bring up the Terminal and run these commands

$ sudo apt-get remove bcmwl-kernel-source
$ sudo apt-get install linux-firmware-nonfree

$ sudo modprobe b43

I did these commands and now my wireless won't allow me to turn it on. Before I could turn it on, but it could not connect to my network (not sure if it could to any other networks.) I'm using a Dell Inspiron 1545. Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01)
==> PCI ID = 14e4:4315 (rev 01) Using Mint 15. I have been looking all over the last few days trying to get the wireless to work to no avail.

*edit*
Reinstalled Mint and ran the commands Ronshere listed and my wireless is now working. Looks to be a little unstable but maybe it will resolve itself. Thanks for the help.
