    Angry Ubuntu on mac No Network adapters

    I have a macbook pro 13in from 2010. I installed ubuntu 10.04 on it and all went well except the fact that it says no network adapters present. I've played around with linux a little bit but I am still very new to this. How can I get the drivers needed to see my network hardware and how do I go about installing them. Playing with computers is fun except when the network adapter driver doesn't work -_- lol.

    Re: Ubuntu on mac No Network adapters

    You shouldn't make multiple posts before 24 hours without getting any replies. It is harmful to your thread because it makes it look (in a general search) as if is getting help while actually it is not.

    Having said that, I shouldn't have posted as well if I couldn't help. But I think I sometimes get lucky with networking issues (at least this one wouldn't go unanswered like the one you linked to )

    Let us first see if Ubuntu actually detected any adapters or not. Please run the following commands in terminal and post back the outputs:
    Code:
    sudo lshw -C network
    If it doesn't give any outputs, then-
    Code:
    lspci -nn
    dmesg | grep -i net
    While posting the outputs, please put them in 'Code' box like above ones by adding [code]..and..[/code] tags respectively at the beginning and end of the outputs (you can click on # at the top of edit box to auto generate them, then copy-paste the outputs in-between the generated tags).

    Also, have you done these basic checks?-

    • If there is a physical switch, make sure it is turned 'On'
    • the adapter is NOT DISABLED in BIOS
    • Is the adapter working on the mac OS part?

    I'm not familiar with macs, but I think these basic steps are same for any computer system.

    As per this page, it looks like you either need to install a backported kernel/module, or would have to resort to ndiswrapper to try windows driver. But I'd wait for an input from josephmills, as he seems to have better experience about this.

    Re: Ubuntu on mac No Network adapters

    yes varunendra is correct if you look at that page you will see that you have to use the 3.2 + kernel in order for this thing to work with the b43 or you can do as he says and go after ndiswrapper. Its up to you. what would you like to do ? I think that 12.04 has the 3.2 kernel in it. any ho let us know if you would like to upgrade your kernel or if you would like to try ndiswrapper.
