Can't get online with Atheros AR9462 [Solved]

Postby bjolly on Thu Jan 10, 2013 1:15 pm

The wife went out and bought me a Laptop running Windows 7. So i have just dual booted Windows 7 and Linuxmint-14.1-MATE. Everything went along great until after re-booting and the Linuxmint desktop appeared and i found that no matter what i did i simply could not get online?

So i opened a terminal and run the command "lspci" the contents of which i have posted below. I have also run another command "dmesg" the output of which i shall save unless i am asked to provide. Hope someone can help because Linuxmint is the only Linux OS i want to use on a regular basis.

Please share instead the output of:
Code: Select all
inxi -SNxz

And please share whether you were using the wired or wireless interface, and if you haven't already please try the other also and share if that one does work.

Hi xenopeek
I tried to set up Linuxmint on a wireless connection. I couldn't try to set it up on a wired connection because the laptop does not have an ethernet port.

Code: Select all
mean@monkey-linux-mint-uk ~ $ inxi -SNxz
System: Host: monkey-linux-mint-uk Kernel: 3.5.0-17-generic x86_64 (64 bit, gcc: 4.7.2)

Network: Card-1: Realtek RTL 8111/8168B PCI Express Gigabit Ethernet controller
              driver: r8169 ver: 2.3LK-NAPI port: 2000 bus-ID: 02:00.2
              Card-2: Atheros AR9462 Wireless Network Adapter driver: ath9k bus-ID: 03:00.0

Well, you have an ethernet network interface (Card-1 in above) so perhaps have another hunt for it :wink: Or is it a super slim laptop, with one of those mini ethernet network interfaces for which you need a dongle?

This wireless chip is certified by Ubuntu, so it should work. One recommendation for having a very slow connection on it is to disable a problematic feature. To do so, run the following command from a terminal and then reboot.
Code: Select all
echo options ath9k nohwcrypt=1 | sudo tee -a /etc/modprobe.d/ath9k.conf

You'll be asked for your password; note that on the terminal you do not get any feedback as you type a password.

If that didn't help, please share the output of this command:
Code: Select all
mintwifi

Drats, then I'm not sure of a next step. I've moved your topic here and updated the subject to add some specifics of your problem. Hopefully another member here will be able to help you with this.

Would like to say a big thanks to xenopeek for all the time and help he so readily give.

Hope someone can come up with a solution. Shall just have to wait and see?
Shall log on in the morning to see if any more help is forth comming.
Good night all

Perhaps one addition; what is the make & model of this laptop? There may be something to be found with that.

Have finally managed to install Linux Mint 14 "Nadia" and still have internet access. Did a fresh install of Linux Mint onto my laptop with a wired connection. I still have to find out how to configure the laptop for a wireless connection. Would also like to know how to change Nat to Bridged the next time i attempt to use VirtualBox.
