Connecting to Wireless Network on Macbook [SOLVED]

Postby FA22raptero on Sun Jan 20, 2013 8:55 pm

Hello there Linux Community!

I am new here, and i'm pretty sure that one of the last things you guys needs is another newby walking around. But alas, I am here... and was hoping for some help from you lovely ladies and gentlemen of the operating system underworld! I've spent the last two hours looking for a solution to my problem. Essentially, I just installed Mint 14 MATE and the first thing i'm trying to do is connect to my house's wireless network. I have been able to connect to a Ethernet cable just fine, and I am using my own computer as I type this. I do, however, need to be able to connect wirelessly. I was hoping you could help me out!

To start, I realise that in using a Macbook, there are often firmware problems and often times we have to download Broadcom firmware packages for Linux to get things working. I have tried looking around for the last two hours, but have been unable to find which Broadcom chipset I have and whether I even need to download one. Despite this, I randomly tried a few terminal commands to download some packages, with no success.

Another question I have is even once I have downloaded the firmware, will the option to simply connect to wireless show up in the connection button on the toolbar. For instance, on OS X you just click the "airport" symbol and a list of close networks shows up. Simply enter the wassword and bam, you're connected. On windows, it's similar, where you can see a list of available networks and you connect by entereing a password. On Linux however, when I select the little "connection" button just to the left of the clock, the only options that I see are "wired network" and "VPN network". When I go to "configure VPN" I have the option to select the "wired" "wireless" Mobile broadband" "VPN" and "DSL" tabs. When I select the Wireless tab, I click Add and try to add all the information I know, such as SSID and WEP2 Personal password, I still can't figure out how to connect.

I really appreciate any and all help that I can get! Also, below is the network log you guys ask for. :D

P.S. my computer is a Macbook Pro 15 Incht that I purchased in 2011. I used to know where to find all the hardware information on my computer, but am no longer familiar. I'm guessing you will need to know my Broadcom number, so just let me know how to find it and I will do it ASAP!

Thanks a lot snipson. I entered the code and got the following (see below). My understanding from this information is that my Broadcom device is B43. I already have the fwcutter devices installed on my computer. With this, how do I see a list of available networks that exist? As I already posted, on windows/os x you can simply see a list of wireless networks that are in range. Is this possible with Linux? Or do I have to enter all of my information manually. In that case, any idea on how to locate my SSID? I am connected to the same home network, just through ethernet instead. Thanks again!

The icon in the date tray that looks like two cables connecting, you should be able to left click on it and it show you the wireless networks...

What does
sudo lshw -C network

give you?

Hi snison,

I entered the command, please see the results below. As for the network connection shortcut by the clock, no, the option is not there (I already tried that). When I click it, I see:

Wired Network (greyed out, i'm assuming because i'm connected to a wired network)
Wired connection 1 (representing my ethernet connection)
Disconnect
VPN connections

I had this same problem on a windows computer once. Obviously it's not the same, but as far as I know this often happens when the right drivers aren't installed. Bellow is the information you requested!

Thanks a lot!

If you get an Interface doesn't support scanning message then try the following 2 options:

Test if your interface is UP: sudo ifconfig wlan0 up

Try adding sudo when doing the scan: iwlist wlan0 s

When I type sudo ifconfig wlan0 up , I get wlan0: ERROR while getting interface flags: No such device. When I write sudo iwlist wlan0 s it just repeats "Interface doesn't support scanning".

Hi guys
I was having the exactly same problem, though using an Aspire One 786, not a Mac, and I was following up the discussion, but it suddenlly ended...
snison, what do you mean by "check PM" ?
FA22raptero, did you managed to get connected?

Thanks!

Hey, so if you read this far no fix, just know that as much as the suggestions by (the guys helping me out) were super awesome and I appreciate it, they didn't seem to help. However, whether because of his help or something else, after a week I gave up... then I just restarted my computer and everything worked fine and I could see all my internet connections. Anyways, hoope I don't annoy anyone with "solved" but something fixed it. Thanks for all the help!
