Wireless problems with atheros AR9485 Wireless Network Adapter.

[karnpreet]

Hello,

I've recently purchased a custom built computer with no OS on it. I installed ubuntu onto it and it has a ASUS motherboad P8z77-V and a atheros AR9485 Wireless Network Adapter. It recognises the wireless router I have but it doesn't connect at all to it, it just keeps asking for the password. I really have no clue about computers so I was wondering whether someone can help me. I have the CD for the motherboard but for some reason it doesn't seem to run everytime I put it in. What shall I do?

Hi and Welcome.

Please open a terminal (CTRL+ALT+T) and copy-paste from here bellow commands one line at time.

lsb_release -rcd ; uname -r
lspci -nnk | grep -iA2 net
lsmod
rfkill list all
nmcli nm status

Post the results back here and put the results inside [CODE] tags.

Thanks

[karnpreet]

sorry I'm taking ages to reply back, I have no internet connection on my desktop computer so I'm having to type it all out onto this, i will be posting it soon

Hello,

I've recently purchased a custom built computer with no OS on it. I installed ubuntu onto it and it has a ASUS motherboad P8z77-V and a atheros AR9485 Wireless Network Adapter. It recognises the wireless router I have but it doesn't connect for a while, and then it connects before disconnecting before a page loads up. I really have no clue about computers so I was wondering whether someone can help me. I have the CD for the motherboard but for some reason it doesn't seem to run everytime I put it in. I've just changed the channel setting on the modem as well to see whether it was that but that doesn't make a difference at all. I was told by someone to print this out as you might find it helpful in solving the problem:-

OK,
2 things I can see.

1) The network-manager seems disabled-disconnected

RUNNING STATE WIFI-HARDWARE WIFI WWAN-HARDWARE WWAN 
running disconnected enabled enabled enabled disabled

2)You use the ath9k module .This module has an option that might help you to stabilize your connection.

First try with network-manager , this command

nmcli nm enabled true

and see if things are better.

OR

Try this code

echo 'options ath9k nohwcrypt=1' | sudo tee /etc/modprobe.d/ath9k.conf

and reboot your PC to see.

Thanks

If you have "no clue" about computers, I'm going to suggest you stick to the 12.04 LTS version of Ubuntu, because that one will be supported until 2017 whereas 12.10 will be supported for only another 18 months.

You'll probably have the same wireless issues in 12.04, though. It seems one solution for your card is found here:

http://ubuntuforums.org/showthread.p...heros+acer+722

First try the fix there to disable hardware encryption. Open terminal window then type:

sudo modprobe -rfv ath9k
sudo modprobe -v ath9k nohwcrypt=1

If that works, make it permanent this way:

echo "options ath9k nohwcrypt=1" | sudo tee /etc/modprobe.d/ath9k.conf

I'm having the same problem (moving from Win7 to Ubuntu 13.04) but non of the above solutions helped.
