Ubuntu on mac No Network adapters

**jessepage1989** · February 15th, 2012

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.

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.
